&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Um corpo tem carga negativa se nele há um excesso de elétrons e positiva se há falta de elétrons em relação ao número de prótons.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;A quantidade de carga elétrica de um corpo é determinada pela diferença entre o número de prótons e o número de elétrons que um corpo contém. O símbolo da carga elétrica de um corpo é Q, expresso pela unidade&amp;nbsp;&lt;b&gt;coulomb&lt;/b&gt;&amp;nbsp;(C). A carga de um coulomb negativo significa que o corpo contém uma carga de 6,25 x 10&lt;sup&gt;&lt;small&gt;18&lt;/small&gt;&lt;/sup&gt;&amp;nbsp;mais elétrons do que prótons.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;h3&gt;
&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;

Diferença de Potencial&lt;/span&gt;&lt;/h3&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Graças à força do seu campo eletrostático, uma carga pode realizar trabalho ao deslogar outra carga por atração ou repulsão. Essa capacidade de realizar trabalho é chamada potencial. Quando uma carga for diferente da outra, haverá entre elas uma diferença de potencial(E).&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;A soma das diferenças de potencial de todas as cargas de um campo eletrostático é conhecida como&amp;nbsp;&lt;i&gt;força eletromotriz&lt;/i&gt;.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;A diferença de potencial (ou tensão) tem como unidade fundamental o&amp;nbsp;&lt;b&gt;volt&lt;/b&gt;(V).&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;h3&gt;
&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;

Corrente&lt;/span&gt;&lt;/h3&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Corrente (I) é simplesmente o fluxo de elétrons. Essa crrente é produzida pelo deslocamento de elétrons através de uma ddp em um condutor. A unidade fundamental de corrente é o&amp;nbsp;&lt;b&gt;ampère&lt;/b&gt;&amp;nbsp;(A). 1 A é o deslocamento de 1 C através de um ponto qualquer de um condutor durante 1 s.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;center&gt;&lt;i&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;I=Q/t&lt;/span&gt;&lt;/i&gt;&lt;/center&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;O fluxo real de elétrons é do potencial negativo para o positivo. No entanto, é convenção representar a corrente como indo do positivo para o negativo.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;h3&gt;


&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;Correntes e Tensões Contínuas e Alternadas&lt;/span&gt;&lt;/h3&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;A corrente contínua (CC ou DC) é aquela que passa através de um condutor ou de um circuito num só sentido. Isso se deve ao fato de suas fontes de tensão (pilhas, baterias,...) manterem a mesma polaridade de tensão de saída.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Uma fonte de tensão alternada alterna a polaridade constantemente com o tempo. Conseqüentemente a corrente também muda de sentido periódicamente. A linha de tensão usada na aioria das residências é de tensão alternada.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;h3&gt;
&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;

Resistência Elétrica&lt;/span&gt;&lt;/h3&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Resistência é a oposição à passagem de corrente elétrica. É medida em&amp;nbsp;&lt;b&gt;ohms&lt;/b&gt;&amp;nbsp;(&lt;span style=&quot;font-family: symbol;&quot;&gt;W&lt;/span&gt;). Quanto maior a resistência, menor é a corrente que passa.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Os resistores são elementos que apresentam resistência conhecida bem definida. Podem ter uma resistência fixa ou variável.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;h3&gt;
&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;

Lei de Ohm&lt;/span&gt;&lt;/h3&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Um circuito elétrico consta de, na prática, pelo menos quatro partes: fonte de fem (força eletromotriz), condutores, carga e intrumentos de controle.&amp;nbsp;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;A lei de OHM diz respeito à relação entre corrente, tensão e resistência:&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;center&gt;&lt;i&gt;&lt;big&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;I=V/R&lt;/span&gt;&lt;/big&gt;&lt;/i&gt;&lt;/center&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;Onde:&lt;/span&gt;&lt;br /&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;I é a corrente em ampères&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;V é a tensão em volts&lt;/span&gt;&lt;/li&gt;
&lt;li&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;R é a resistência em ohms&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Potência&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;A potência elétrica numa parte de um circuito é igual à tensão dessa parte multiplicada pela corrente que passa por ela:&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;center&gt;&lt;i&gt;&lt;big&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;P=VI&lt;/span&gt;&lt;/big&gt;&lt;/i&gt;&lt;/center&gt;&lt;center&gt;&lt;i&gt;&lt;big&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/big&gt;&lt;/i&gt;&lt;/center&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;Combinando essa equação com&amp;nbsp;&lt;i&gt;I=V/R&lt;/i&gt;, temos:&amp;nbsp;&lt;i&gt;&lt;big&gt;P=RI&lt;sup&gt;&lt;small&gt;2&lt;/small&gt;&lt;/sup&gt;&lt;/big&gt;&lt;/i&gt;&amp;nbsp;e&amp;nbsp;&lt;i&gt;&lt;big&gt;V&lt;sup&gt;&lt;small&gt;2&lt;/small&gt;&lt;/sup&gt;/R&lt;/big&gt;&lt;/i&gt;.&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;h3&gt;
&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;

Associações de Resistores&lt;/span&gt;&lt;/h3&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Os resistores podem se associar em paralelo ou em série. (Na verdade existem outras formas de associação, mas elas são um pouco mais complicadas e serão vistas futuramente)&lt;/span&gt;&lt;br /&gt;
&lt;h4&gt;
&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;

Associação Série&lt;/span&gt;&lt;/h4&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Na associação série, dois resistores consecutivos têm um ponto em comum. A resistência equivalente é a soma das resistências individuais. Ou seja:&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;center&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;R&lt;sub&gt;eq&lt;/sub&gt;&amp;nbsp;= R&lt;sub&gt;1&lt;/sub&gt;&amp;nbsp;+ R&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;+ R&lt;sub&gt;3&lt;/sub&gt;&amp;nbsp;+ ...&lt;/span&gt;&lt;/center&gt;&lt;br /&gt;
&lt;h4&gt;
&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;

Associação Paralelo&lt;/span&gt;&lt;/h4&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;Dois resistores estão em paralelo se há dois pontos em comum entre eles. Neste caso, a fórmula para a resistência equivalente é: 1/R&lt;sub&gt;eq&lt;/sub&gt;&amp;nbsp;= 1/R&lt;sub&gt;1&lt;/sub&gt;&amp;nbsp;+ 1/R&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;+ 1/R&lt;sub&gt;3&lt;/sub&gt;&amp;nbsp;+ ...&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;&lt;a href=&quot;http://www.blogger.com/blogger.g?blogID=6530056112999863021&quot; name=&quot;capacit&quot;&gt;&lt;/a&gt;&lt;/span&gt;&lt;br /&gt;
&lt;h3&gt;
&lt;span style=&quot;color: orange; font-size: x-small;&quot;&gt;

Capacitor&lt;/span&gt;&lt;/h3&gt;
&lt;span style=&quot;font-size: x-small;&quot;&gt;O capacitor é constituído por duas placas condutoras paralelas, separadas por um diélétrico. Quando se aplica uma ddp nos seus dois terminais, começa a haver um movimento de cargas para as placas paralelas. A&amp;nbsp;&lt;b&gt;capacitância&lt;/b&gt;&amp;nbsp;de um capacitor é a razão entre a carga acumulada e a tensão aplicada.&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;center&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;C = Q/V&lt;/span&gt;&lt;/center&gt;&lt;span style=&quot;font-size: x-small;&quot;&gt;Deve-se também ter em mente que a capacitância é maior quanto amior for a área das placas paralelas, e quanto menor for a distância entre elas.&amp;nbsp;
&lt;/span&gt;&lt;br /&gt;

Tais efeitos dependem de fatores como a intensidade de corrente elétrica, duração, resistência da porção do corpo envolvida. Suponha, por exemplo, um choque produzido por uma corrente de apenas 4mA e que a resistência da porção do corpo envolvida seja de 3000W. Então, podemos afirmar que o choque elétrico pode ter sido devido ao contato com:&amp;nbsp;&amp;nbsp;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;

Foram feitas duas medições: primeiro a 120 volts e depois a 40 volts. Calculou-se a resistência da lâmpada aplicando-se a lei de Ohm e obteve-se resistência sensivelmente maior para 120 volts. Pode-se afirmar que: &amp;nbsp;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;

&lt;br class=&quot;Apple-interchange-newline&quot; /&gt;Como ter um ótimo desempenho na sua redação do ENEM&amp;nbsp;&lt;/div&gt;

A redação é ponto fundamental do Enem. O texto, do gênero dissertativo-argumentativo, vale 1.000 pontos, mesmo valor atribuído às outras provas, como a de linguagem. Ou seja, a redação equivale a 20% da nota final do participante. Por isso, o bom desempenho é fundamental e, para obtê-lo, é preciso atenção redobrada. Os avaliadores querem saber se o estudante sabe refletir sobre os mais variados assuntos ou se ele é apenas um repetidor de chavões. É preciso ter ideias próprias e saber sustentá-las.&lt;/div&gt;
&lt;div style=&quot;border: 0px; color: #333333; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 18px; list-style: none; margin-bottom: 10px; outline: 0px; padding: 0px;&quot;&gt;

O formato da prova já é consagrado. Os examinadores oferecem um tema explícito – o que significa que o candidato não precisa deduzir o que está sendo solicitado – e textos e charges servem como guia. O material de apoio pode ser utilizado pelo participante para dar consistência à redação, mas é imprescindível que sejam somadas ideias provenientes do repertório pessoal. Ater-se apenas às informações fornecidas não é um procedimento bem visto pelos avaliadores.&lt;/div&gt;

Essa redução - feita com o uso da escala - torna possível a manutenção da proporção do espaço representado. É fácil reconhecer um mapa do&amp;nbsp;&lt;/span&gt;&lt;a href=&quot;http://educacao.uol.com.br/geografia/mapa-brasil.jhtm&quot; style=&quot;color: #666666; font-family: arial; font-size: 12px;&quot;&gt;Brasil&lt;/a&gt;&lt;span style=&quot;color: #444444; font-family: arial; font-size: 12px;&quot;&gt;, por exemplo, independente do tamanho em que ele é apresentado, pois a sua confecção obedeceu a determinada escala, que mantém a sua forma. A escala cartográfica estabelece, portanto, uma relação de proporcionalidade entre as distâncias lineares num desenho (mapa) e as distâncias correspondentes na realidade.&lt;/span&gt;
&lt;br /&gt;
&lt;span style=&quot;color: #444444; font-family: arial; font-size: 12px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;color: #444444; font-family: arial; font-size: 12px;&quot;&gt;A escala numérica é estabelecida através de uma relação matemática, normalmente representada por uma razão, por exemplo: 1: 300 000 (1 por 300 000). A primeira informação que ela fornece é a quantidade de vezes em que o espaço representado foi reduzido. Neste exemplo, o mapa é 300 000 vezes menor que o tamanho real da superfície que ele representa.&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;color: #444444; font-family: arial; font-size: 12px;&quot;&gt;Na escala numérica as unidades, tanto do numerador como do denominador, são indicadas em cm. O numerador é sempre 1 e indica o valor de 1cm no mapa. O denominador é a unidade variável e indica o valor em cm correspondente no território. No caso da escala exemplificada (1: 300 000), 1cm no mapa representa 300 000 cm no terreno, ou 3 km.&lt;/span&gt;&lt;br /&gt;
Aplicação da Escala&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: arial; font-size: 12px;&quot;&gt;&lt;span style=&quot;color: #444444;&quot;&gt;A escala (E) de um mapa é a relação entre a distância no mapa (d) e a distância real (D). Isto é:&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;&lt;span style=&quot;color: red;&quot;&gt;E =d / D&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
Pode-se dizer, sumariamente, que uma ação terrorista tem por objetivo atingir diretamente a população, um órgão ou uma instalação governamental, criando algum tipo de instabilidade social, de modo que se pressione um governo a respeito daquilo que se quer.&lt;span&gt;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
No Brasil, a Comissão de Relações Exteriores e Defesa Nacional (CREDEN) classifica como ato terrorista: “Ato com motivação política ou religiosa que emprega a força ou a violência física ou psicológica, para infundir terror, intimidade ou coagindo as instituições nacionais, a população ou um segmento da sociedade”.&lt;span&gt;&amp;nbsp;&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
Os atentados terroristas de 11 de setembro de 2001, executados pelo grupo fundamentalista islâmico denominado&amp;nbsp;&lt;em&gt;Al-Qaeda&lt;/em&gt;, representaram o início de uma nova fase da História mundial. A maneira como foram organizados e executados mostrou como é possível atingir, tão profundamente, “o coração” da maior potência do mundo de uma maneira simples e eficiente. Como uma organização não-governamental, clandestina, que tinha como base o interior do Afeganistão, conseguiu tanto êxito?&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
Sem dúvida, depois dos atentados terroristas de 11 de setembro de 2001, o contexto político-diplomático internacional se modificou. Após a ação da Al-Qaeda, os EUA desenvolveram uma nova doutrina de ação de defesa baseada na&amp;nbsp;&lt;em&gt;guerra preventiva&lt;/em&gt;, podendo agir de maneira unilateral em qualquer lugar onde, ao seu ver, houver indícios de ações contra a segurança interna do país.&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;span&gt;&amp;nbsp;&lt;/span&gt;Os atentados de 11 de setembro acabaram por dar respaldo ao domínio da tendência política conservadora republicana nas ações do governo Bush, criando assim uma postura diplomática inflexível e conservadora dentro do projeto governamental de “guerra contra o terror”. Outro ponto importante foi que, depois dos atentados de 11 de setembro de 2001, o mundo assistiu ao enfraquecimento da ONU, frente às ações unilaterais do governo&lt;strong&gt;&lt;span style=&quot;color: red;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;/strong&gt;&lt;span&gt;norte-americano.&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;span&gt;Com isso, os EUA passaram por cima&lt;/span&gt;&amp;nbsp;da Organização das Nações Unidas (ONU), tornando-a, de fato, uma instituição inoperante frente aos acontecimentos mundiais. Após os atentados de 11 de setembro, foram duas guerras preventivas executadas pelo EUA sem aprovação da ONU: Afeganistão (2002) e Iraque (2003).&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
Por outro lado, a estrutura organizacional da Al-Qaeda atua em células organizacionais independentes, distribuídas pelo mundo. A Al-Qaeda disseminou sua ideologia e sua metodologia operacional usando os meios globalizados de comunicação, de forma a tornar-se uma estrutura descentralizada com células operacionais em várias partes do mundo.&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
Os ataques realizados em Madrid (11 de março de 2004) e em Londres (7 de julho de 2005) mostraram essa flexibilidade e revelaram a impossibilidade de se antever um ataque terrorista planejado pela Al-Qaeda.&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;span&gt;Em maio de 2011, após quase dez anos de ocupação militar e aproximadamente US$ 400 bilhões gastos, o principal objetivo da guerra foi atingido, o líder da Al Qaeda e organizador dos atentados de 11 de setembro, Osama Bin Laden, foi localizado e morto em um ataque militar na cidade de Abbottabad no Paquistão. O sucesso da operação provocou uma onda diversificada de reações pelo mundo, desde protestos populares realizados no próprio Paquistão até congratulações por parte de chefes de estado de vários pontos do mundo ao presidente Barack Obama. Certamente a Al-Qaeda não deixará de atuar e o risco de um atentado deverá ser tratado como iminente&lt;/span&gt;&lt;/div&gt;
&lt;div align=&quot;justify&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;
Após uma década dos atentados de 11 de setembro, o mundo ainda procura uma solução definitiva para os problemas ligados ao terrorismo que envolvem aspectos políticos, sociais e econômicos. Sendo assim, o terrorismo acabou tornando-se o principal fenômeno global do início do século XXI, marcando permanentemente o início de uma nova era na história mundial.&lt;/div&gt;
&lt;div align=&quot;justify&quot; class=&quot;corpotexto&quot; style=&quot;color: black; font-family: Arial, Helvetica, sans-serif; font-size: 12px;&quot;&gt;

Essa rivalidade se tornou o principal motivo da Primeira Guerra Mundial, dando princípio à “nova era imperialista” onde os EUA se tornaram o centro do imperialismo mundial.&lt;br /&gt;&lt;br /&gt;Os principais países que foram colonizados fora : Ásia e África.</content><link rel='replies' type='application/atom+xml' href='http://vestibular-pss.blogspot.com/feeds/396588472881764077/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://vestibular-pss.blogspot.com/2011/08/imperialismo-partilha-do-mundo.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6530056112999863021/posts/default/396588472881764077'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6530056112999863021/posts/default/396588472881764077'/><link rel='alternate' type='text/html' href='http://vestibular-pss.blogspot.com/2011/08/imperialismo-partilha-do-mundo.html' title='Imperialismo - Partilha do Mundo'/><author><name>Kleython Lacerda</name><uri>http://www.blogger.com/profile/03183081513388035085</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='24' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjnH0AtB1cF9WGWvzld9pdkYnH8s9w49pNG3xJEJBjptdwZ8sPLqC1hHcE0TaERihqWWNlx_sTHVgqKVpJ2dhmwrDByWelMPMFNZm_Em3U935WH_rOWQ6s9sz4KGYefvL4/s220/PQAAACSbke85Uv6LK9-EVGtZrWUSr0X_k2H5o22fapMcUIEugXQ-ot0ZghpiuOht954wvuO1ZI7Ymp0Hzx6_6KNDensAm1T1UCIABzRpzjySCtVU9YrjW9uZcMLp.jpg'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6530056112999863021.post-3454062215422125165</id><published>2011-08-22T12:23:00.000-07:00</published><updated>2011-08-22T12:46:02.316-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="By: Kleython Lacerda"/><title type='text'>I Guerra Mundial / Exercício de Vestibular</title><content type='html'>I Guerra Mundial&lt;br /&gt;&lt;br /&gt;  - Paz Armada&lt;br /&gt;&lt;br /&gt;A partir do final do século XIX , apareceram fortes índices de que a Economia Mundial já estava descentralizada  . Os Estados Unidos da América , se destacavam na indústria química e automobilística . A Alemanha surpreendia a Europa. Os dois países já possuíam uma produção de ferro e aço maior que a inglesa. Com isso a Alemanha , queria uma nova divisão colonial , para que pudesse atender as necessidades de mercado de matérias-primas . A Inglaterra , como era detentora do maior império colonial ,e do maior volume de exportações , para se defender , se militarizava rapidamente .  Isso tudo , deu-se início a uma nova fase da guerra : Conhecida como Paz Armada.              &lt;br /&gt;&lt;br /&gt;  - Principais pontos da Alemanha&lt;br /&gt;&lt;br /&gt;* A Alemanha se unificou durante { 1870 - 1871 }.&lt;br /&gt;* Principal Líder Bismarck . Política de exportação.&lt;br /&gt;* Para manter a paz e as fronteiras alemãs , Bismarck em 1880 , criou a Tríplice Aliança ( Itália , Alemanha e Áustria-Hungria )&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;  - Tríplice Entente &lt;br /&gt;&lt;br /&gt;* Formado principalmente por ( França , Inglaterra , Rússia )&lt;br /&gt;&lt;br /&gt;  - O Estopim da Guerra&lt;br /&gt;&lt;br /&gt;O Assassinato do Príncipe Francisco Ferdinando (28/06/1914) – herdeiro do trono austríaco. Foi assassinado por um fanático estudante bosníano, Gravilo Princip, na cidade de Serajevo. A Áustria -Hungria exigiu uma satisfação da Sérvia, onde o crime fora tramado, por meio de um ultimato. A Rússia, decidida a não admitir uma humilhação à Sérvia, rejeitou as propostas conciliatórias da Alemanha e decretou a mobilização geral. A Alemanha, aliada da Áustria, declarou guerra à Rússia no dia 1.o de agosto e, dois dias depois, à França. Tinha inicio a Primeira Guerra Mundial.&lt;br /&gt;&lt;br /&gt;  - Tratado de Versalhes&lt;br /&gt;&lt;br /&gt;Em Versalhes, em 1919, reuniu-se a Conferência da Paz, sob a liderança dos 4 grandes: Clemenceau, representante da França; Lloyd George, representante da Inglaterra; Woodrow Wilson, representante dos Estados Unidos; e Orlando, representante da Itália. Este tratado impôs duras determinações aos alemães.&lt;br /&gt;&lt;br /&gt;  - Fase da Guerra&lt;br /&gt;&lt;br /&gt;a) Guerra do Movimento (1914) – Os alemães começaram a luta com um ataque à Bélgica, neutra, marchando depois rumo a Paris. O plano francês era invadir Alsácia e Lorena e proteger a fronteira belga; os alemães atacaram Liège. Na batalha do Marne os alemães foram derrotados pelo general Joffre, obrigando-os a retroceder para Leste, depois de perderem milhares de soldados e armamentos. Essa batalha salvou momentaneamente a França. Mas os alemães, não podendo levar avante a investida inicial, firmaram-se no Nordeste da França, abrindo trincheiras, como o fizeram também os franceses, os ingleses e os belgas.&lt;br /&gt;&lt;br /&gt;b) Guerra de Trincheiras (1915-1917) – Abriram-se trincheiras em toda a frente ocidental. O armamento e o aparelhamento aéreo despertaram um novo surto industrial acelerado. Novas armas apareceram. Em 1916, os alemães atacaram Verdun, defendida pelo general Pétain. Foi um insucesso dos alemães. Morreram cerca de 600 mil homens. Na batalha naval da Jutlândia, os ingleses foram os vencedores.&lt;br /&gt;&lt;br /&gt;c) Saída da Rússia – Com o triunfo da Revolução Russa de 1917, onde os bolcheviques estabeleceram-se no poder, foi assinado um acordo com a Alemanha para oficializar sua retirada do grande conflito. Este acordo chamou-se Tratado de Brest-Litovsk, que impôs duras condições para a Rússia.&lt;br /&gt;&lt;br /&gt;d) Entrada dos Estados Unidos – Os norte-americanos tinham muito investimentos nesta guerra com seus amigos aliados (Inglaterra e França). Era preciso garantir o recebimento de tais investimentos. Utilizou-se como pretexto o afundamento do navio “Lusitânia”, que conduzia passageiros norte-americanos.&lt;br /&gt;&lt;br /&gt;e) Participação do Brasil – Os alemães, diante da superioridade naval da Inglaterra, resolveram empreender uma guerra submarina sem restrições. Na noite de 3 de abril de 1917, o navio brasileiro “Paraná” foi atacado pelos submarinos alemães perto de Barfleur, na França. O Brasil, presidido por Wenceslau Brás, rompeu as relações com Berlim e revogou sua neutralidade na guerra. Novos navios brasileiros foram afundados. No dia 25 de outubro, quando recebeu a noticia do afundamento do navio “Macau”, o Brasil declarou guerra à Alemanha. Enviou auxilio à esquadra inglesa no policiamento do Atlântico e uma missão médica.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;  - Consequências da Guerra&lt;br /&gt;&lt;br /&gt;a) O aparecimento de novas nações.&lt;br /&gt;&lt;br /&gt;b) Desmembramento do império Austro- Húngaro.&lt;br /&gt;&lt;br /&gt;c) A hegemonia do militarismo francês, em decorrência do desarmamento alemão.&lt;br /&gt;&lt;br /&gt;d) A Inglaterra dividiu sua hegemonia marítima com os Estados Unidos.&lt;br /&gt;&lt;br /&gt;e) O enriquecimento dos Estados Unidos.&lt;br /&gt;&lt;br /&gt;f) A depreciação do marco alemão, que baixou à milionésima parte do valor, e a baixa do franco e do dólar.&lt;br /&gt;&lt;br /&gt;g) A crise de 1929: os governos tiveram que intervir na economia com medidas severas.&lt;br /&gt;&lt;br /&gt;h) O protecionismo que impossibilitou a Alemanha de pagar suas dívidas por meio de exportação.&lt;br /&gt;&lt;br /&gt;i) O encarecimento do custo de vida.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt; &lt;br /&gt;                         &lt;span style=&quot;font-weight:bold;&quot;&gt;Observação !!!&lt;/span&gt; &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;A I Guerra Mundial , foi diretamente a disputa entre a Alemanha e a Inglaterra . Pois a Inglaterra , ficou com medo da Alemanha crescer economicamente e invadisse os seu territórios e combatesse diretamente as suas exportações.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;-------------------------------------------------------------------- Hora de Praticar Um Pouco Mais !!!&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;01.

A intensidade do campo elétrico nesse ponto é:  &lt;br /&gt;&lt;br /&gt;      a) 1,6 . 10-6N/C&lt;br /&gt;      b) 1,3 . 10-5N/C&lt;br /&gt;      c) 2,0 . 103N/C&lt;br /&gt;      d) 1,6 . 105N/C&lt;br /&gt;      e) 4,0 . 105N/C   &lt;br /&gt; &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;02. (FCC) Uma carga pontual Q, positiva, gera no espaço um campo elétrico. Num ponto P, a 0,5m dela, o campo tem intensidade E=7,2.106N/C. Sendo o meio vácuo onde K0=9.109 unidades S. I., determine Q. &lt;br /&gt;&lt;br /&gt;      a) 2,0 . 10-4C&lt;br /&gt;      b) 4,0 . 10-4C&lt;br /&gt;      c) 2,0 . 10-6C&lt;br /&gt;      d) 4,0 . 10-6C&lt;br /&gt;      e) 2,0 . 10-2C   &lt;br /&gt; &lt;br /&gt;&lt;br /&gt;&lt;br /&gt;03. (F. C. M. SANTA CASA) Em um ponto do espaço:  &lt;br /&gt;&lt;br /&gt;I. Uma carga elétrica não sofre ação da força elétrica se o campo nesse local for nulo.&lt;br /&gt;II. Pode existir campo elétrico sem que aí exista força elétrica.&lt;br /&gt;III.

Fazer uma boa Dissertação é fundamental para conseguir uma boa média no exame.&lt;br /&gt;
A Dissertação é um tipo de texto opinativo aonde o escritor defende um ponto de vista com o uso de argumentos. A Redação do Enem avalia cinco competências:&lt;br /&gt;
1. Domínio da língua culta&lt;br /&gt;
2. Compreensão da proposta de Redação e aplicação de conceitos de várias áreas do conhecimento para desenvolver o tema.&lt;br /&gt;
3. Selecionar, relacionar, organizar e interpretar informações em defesa de um ponto de vista.&lt;br /&gt;
4. Demonstração de conhecimento dos mecanismos lingüísticos necessários para construir a argumentação.&lt;br /&gt;
5. Elaborar proposta de ação para enfrentar o problema respeitando os direitos humanos.&lt;br /&gt;
Para elaborar uma boa dissertação, o estudante pode seguir algumas dicas.&lt;br /&gt;
Transforme a proposta em pergunta, como por exemplo: “As novelas brasileiras podem ser consideradas educativas?”. Com base isso, tente pensar em três argumentos que responderiam essa pergunta. Desenvolva cada argumento seguindo a seguinte estrutura.&lt;br /&gt;
Introdução&lt;br /&gt;
Argumento 1&lt;br /&gt;
Argumento 2&lt;br /&gt;
Argumento 3&lt;br /&gt;
Conclusão&lt;br /&gt;
Na conclusão, posicione-se a respeito e sugira uma solução para o tema proposto.&lt;br /&gt;
A introdução apesar de não ser essencial é extremamente recomendada. Nela você deve apresentar o tema em poucas frases, em torno de 3 ou 4 linhas.&lt;br /&gt;
O título não é obrigatório no Enem, mas caso você faça outros exames em seja necessário, uma boa dica é não utilizar verbo no título.</content><link rel='replies' type='application/atom+xml' href='http://vestibular-pss.blogspot.com/feeds/8261087046651994295/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://vestibular-pss.blogspot.com/2011/08/dissertacao.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6530056112999863021/posts/default/8261087046651994295'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6530056112999863021/posts/default/8261087046651994295'/><link rel='alternate' type='text/html' href='http://vestibular-pss.blogspot.com/2011/08/dissertacao.html' title='Dissertação !!!'/><author><name>Kleython Lacerda</name><uri>http://www.blogger.com/profile/03183081513388035085</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='24' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjnH0AtB1cF9WGWvzld9pdkYnH8s9w49pNG3xJEJBjptdwZ8sPLqC1hHcE0TaERihqWWNlx_sTHVgqKVpJ2dhmwrDByWelMPMFNZm_Em3U935WH_rOWQ6s9sz4KGYefvL4/s220/PQAAACSbke85Uv6LK9-EVGtZrWUSr0X_k2H5o22fapMcUIEugXQ-ot0ZghpiuOht954wvuO1ZI7Ymp0Hzx6_6KNDensAm1T1UCIABzRpzjySCtVU9YrjW9uZcMLp.jpg'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6530056112999863021.post-3002377581561704000</id><published>2011-08-04T11:19:00.001-07:00</published><updated>2011-08-04T11:23:11.485-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="By: Kleython Lacerda"/><title type='text'>Principais Blocos Econômicos</title><content type='html'>Principais Blocos Econômicos&lt;br /&gt;
&lt;br /&gt;
Blocos econômicos são grupos de países que tem por objetivo a integração econômica e/ou social. Veja abaixo alguns dos principais Blocos Econômicos.&lt;br /&gt;
&lt;br /&gt;
ALCA&lt;br /&gt;
&lt;br /&gt;
Países: 34 países do continente americano. Exceto Cuba.&lt;br /&gt;
Criação: 1994&lt;br /&gt;
PIB total: US$ 12,6 trilhões&lt;br /&gt;
População: 825,3 milhões&lt;br /&gt;
Objetivo: Trânsito livre pelas fronteiras de bens, serviços e investimentos. Prevê a isenção de impostos alfandegários para a maioria dos itens de comércio entre os países associados.&lt;br /&gt;
Para quem será positivo: Os países competitivos serão os maiores beneficiados, principalmente no gigantesco mercado de consumo dos Estados Unidos. Investimentos em tecnologia que aprimorem a eficiência do processo produtivo, principalmente nos países subdesenvolvidos serão extremamente necessários.&lt;br /&gt;
Para quem será negativo: Países que não são competitivos, ou seja, não possuem tecnologia e falta uma boa educação no país. Esses países poderão ver seus produtos perderem mercado nacional para os produtos “de fora”.&lt;br /&gt;
&lt;br /&gt;
APEC&lt;br /&gt;
&lt;br /&gt;
Países: 17 países e um território: Austrália, Brunei, Canadá, Indonésia, Japão, Malásia, Nova Zelândia, Filipinas, Cingapura, Coréia do Sul, Tailândia, EUA, China, Hong Kong, Taiwan, México, Papua Nova Guiné e Chile.&lt;br /&gt;
Criação: 1989&lt;br /&gt;
PIB Total: US$ 14,1 trilhões&lt;br /&gt;
População: 2.217 milhões&lt;br /&gt;
Objetivo: Pretende ser uma união aduaneira com tarifas zero até 2020.&lt;br /&gt;
Observação: É considerado o maior bloco econômico do mundo e domina 46% das exportações mundiais.&lt;br /&gt;
&lt;br /&gt;
MERCOSUL&lt;br /&gt;
&lt;br /&gt;
Países: Argentina, Bolívia, Brasil, Colômbia, Equador, Paraguai, Uruguai e Venezuela.&lt;br /&gt;
Criação: 1991&lt;br /&gt;
PIB Total: US$ 0,79 trilhão&lt;br /&gt;
População: 217,8 milhões&lt;br /&gt;
Objetivo: Em 1995 entrou em vigor uma zona de livre-comércio, ou seja, grande parte das mercadorias produzidas nos países membros podia ser comercializada internamente sem a cobrança de tarifas de importação.&lt;br /&gt;
Além disso, o Mercosul prevê a criação de uma união aduaneira. Isso significa a padronização das tarifas externas (TECs) para diversas mercadorias. Portanto, os países integrantes poderão importar produtos e serviços, pagando tarifas iguais.&lt;br /&gt;
&lt;br /&gt;
NAFTA&lt;br /&gt;
&lt;br /&gt;
Países: Estados Unidos, México e Canadá.&lt;br /&gt;
Criação: 1994&lt;br /&gt;
PIB Total: US$ 11,4 trilhões&lt;br /&gt;
População: 417,6 milhões de habitantes&lt;br /&gt;
Objetivos: Eliminar tarifas alfandegárias e obstáculos para circulação de bens e serviços; garantir a competição leal, no interior do bloco, para mão-de-obra especializada. Prevê um prazo de 15 anos para alcançar a eliminação dos obstáculos.&lt;br /&gt;

PIB Total: US$ 9,2 trilhões&lt;br /&gt;
População: Aproximadamente 500 milhões de habitantes.&lt;br /&gt;
Objetivo: Eliminação do controle das fronteiras dos países participantes, de modo que permita o livre trânsito de pessoas entre os países; fim das barreiras comerciais, proporcionando uma economia livre e concorrencial; adoção da moeda única em 2002, o euro passa a ser a moeda oficial da União Europeia, extinguindo as moedas nacionais dos países membros que passam a ter o euro como moeda oficial.</content><link rel='replies' type='application/atom+xml' href='http://vestibular-pss.blogspot.com/feeds/3002377581561704000/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://vestibular-pss.blogspot.com/2011/08/principais-blocos-economicos.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6530056112999863021/posts/default/3002377581561704000'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6530056112999863021/posts/default/3002377581561704000'/><link rel='alternate' type='text/html' href='http://vestibular-pss.blogspot.com/2011/08/principais-blocos-economicos.html' title='Principais Blocos Econômicos'/><author><name>Kleython Lacerda</name><uri>http://www.blogger.com/profile/03183081513388035085</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='24' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjnH0AtB1cF9WGWvzld9pdkYnH8s9w49pNG3xJEJBjptdwZ8sPLqC1hHcE0TaERihqWWNlx_sTHVgqKVpJ2dhmwrDByWelMPMFNZm_Em3U935WH_rOWQ6s9sz4KGYefvL4/s220/PQAAACSbke85Uv6LK9-EVGtZrWUSr0X_k2H5o22fapMcUIEugXQ-ot0ZghpiuOht954wvuO1ZI7Ymp0Hzx6_6KNDensAm1T1UCIABzRpzjySCtVU9YrjW9uZcMLp.jpg'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6530056112999863021.post-4258199047970570122</id><published>2011-08-04T11:18:00.003-07:00</published><updated>2011-08-04T11:18:55.416-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="By: Kleython Lacerda"/><title type='text'>Globalização!!!</title><content type='html'>Globalização&lt;br /&gt;
&lt;br /&gt;
A Globalização  é um processo de integração econômica, cultural, social e política. Esse fenômeno é gerado pela necessidade do capitalismo de conquistar novos mercados, principalmente se o mercado atual estiver saturado.&lt;br /&gt;
A intensificação da globalização  aconteceu na década de 70, e ganha grande velocidade na década de 80. Um dos motivos para essa aceleração é o desenvolvimento de novas tecnologias, como por exemplo, no ramo da comunicação.&lt;br /&gt;
Como ocorre a globalização?&lt;br /&gt;
Veja o exemplo  abaixo para ter uma idéia de como acontece a globalização, e o que é ela.&lt;br /&gt;
• O produtor efetua a compra da matéria-prima de qualquer lugar do mundo, onde ela seja barata e de boa qualidade.&lt;br /&gt;
• Instala a sua fábrica aonde a mão de obra é mais barata. O lugar não importa muito para onde serão vendidos os produtos.&lt;br /&gt;
• Após a fabricação do produto, o produtor distribui sua mercadoria para qualquer lugar do mundo que ele desejar.&lt;br /&gt;
Em suma, na globalização você pode comprar um produto que foi fabricado do outro lado do mundo, como por exemplo China, mas utilizando a matéria-prima que foi comprada em outro país.</content><link rel='replies' type='application/atom+xml' href='http://vestibular-pss.blogspot.com/feeds/4258199047970570122/comments/default' title='Postar comentários'/><link rel='replies' type='text/html' href='http://vestibular-pss.blogspot.com/2011/08/globalizacao.html#comment-form' title='0 Comentários'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/6530056112999863021/posts/default/4258199047970570122'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/6530056112999863021/posts/default/4258199047970570122'/><link rel='alternate' type='text/html' href='http://vestibular-pss.blogspot.com/2011/08/globalizacao.html' title='Globalização!!!'/><author><name>Kleython Lacerda</name><uri>http://www.blogger.com/profile/03183081513388035085</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='24' height='32' src='//blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjnH0AtB1cF9WGWvzld9pdkYnH8s9w49pNG3xJEJBjptdwZ8sPLqC1hHcE0TaERihqWWNlx_sTHVgqKVpJ2dhmwrDByWelMPMFNZm_Em3U935WH_rOWQ6s9sz4KGYefvL4/s220/PQAAACSbke85Uv6LK9-EVGtZrWUSr0X_k2H5o22fapMcUIEugXQ-ot0ZghpiuOht954wvuO1ZI7Ymp0Hzx6_6KNDensAm1T1UCIABzRpzjySCtVU9YrjW9uZcMLp.jpg'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-6530056112999863021.post-4325266453979020451</id><published>2011-08-04T11:18:00.001-07:00</published><updated>2011-08-04T11:18:22.217-07:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="By: Kleython Lacerda"/><title type='text'>Regra de Três Simples</title><content type='html'>Regra de três simples é algo banal para muitas pessoas, mas para alguns pode ser “um bicho de sete cabeças”. Em diversos exercícios, e ao longo da vida escolar saber regra de três é muito importante para conseguir resolver certos problemas.&lt;br /&gt;
Para uma regra de três simples é preciso montar uma tabela com as grandezas citados no exercício. As grandezas de mesma espécie devem ser agrupadas na mesma coluna, e as que forem correspondentes devem ser alinhadas na mesma linha.&lt;br /&gt;
Exemplo:&lt;br /&gt;
“Paulo trabalhou 30 dias e recebeu 15 000 reais. Quantos dias terá que trabalhar para receber 20 000 reais?”&lt;br /&gt;
Resolução: Montando a regra de três temos:&lt;br /&gt;
15 000 ___________ 30&lt;br /&gt;
20 000 ___________ x&lt;br /&gt;
O 15 000 e o 30 são grandezas correspondentes, mas não da mesma espécie (15 000 é dinheiro e 30 são dias). Mas 15 000 e 20 000 são da mesma espécie, ou seja ambos são dinheiro.&lt;br /&gt;
Para resolver agora basta multiplicar cruzado, como se fosse um X.&lt;br /&gt;
15 000x = 600 000&lt;br /&gt;

&lt;br /&gt;
          Super dica!!!!&lt;br /&gt;
&lt;br /&gt;
Para você saber qual é o seno e o cosseno dos ângulos notáveis , basta escrever:&lt;br /&gt;
&lt;br /&gt;
Ângulo    30o   45o   60o&lt;br /&gt;
&lt;br /&gt;
Seno      &lt;br /&gt;
Coss&lt;br /&gt;
&lt;br /&gt;
Coloca todos em fração com denominador 2. Ficando assim:&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Ângulo    30o   45o   60o&lt;br /&gt;
&lt;br /&gt;
Seno       /2    /2    /2   &lt;br /&gt;
Coss       /2    /2    /2 &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
E canta a musica : &quot; um , dois três . três , dois , um . Tira raiz de todos , só não tira raiz de um.&quot;  Ficando assim:&lt;br /&gt;
&lt;br /&gt;
Ângulo    30o    45o   60o&lt;br /&gt;
&lt;br /&gt;
Seno      1/2   √2/2   √3/2   &lt;br /&gt;
Coss     √3/2   √2/2    1/2 &lt;br /&gt;
&lt;br /&gt;
Para calcular a tangente , basta dividir o seno com o cosseno de cada ângulo , ficando assil:&lt;br /&gt;
&lt;br /&gt;
Ângulo    30o    45o   60o&lt;br /&gt;
&lt;br /&gt;
Seno      1/2   √2/2   √3/2   &lt;br /&gt;
Coss     √3/2   √2/2    1/2&lt;br /&gt;
tang     √3/3    √2      √3 &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
                                      Hora de Praticar um pouco mais!!!&lt;br /&gt;

-Um escorrego tem superfície plana inclinada e lisa, por onde as crianças deslizam , e de uma escada que dá acesso á rampa . No parque de certa praça , há um escorrego , apoiado em um piso plano e horizontal  cuja escada tem 2m de comprimento e forma um ângulo de 45o com o piso; e a rampa forma um ângulo de 30o com o piso. De acordo com essas informações , diga quanto vale o comprimento da rampa ( superfície plana inclinada e lisa ).&lt;br /&gt;
