&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Fortaleza 11 de Agosto de 2012 &amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; min-height: 17px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;“...50% de vagas na federal para alunos da escola pública ...”&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; min-height: 17px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Essa é a nova REGRA IMPOSTA por políticos aos vestibulares de TODAS as Universidades Federais e Escolas Técnicas Federais.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; min-height: 17px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Vale lembrar que este ano é de ELEIÇÕES e medidas deste porte fazem os POPULACIONISTAS ganharem votos !!!&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; min-height: 17px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Agora analisemos a ideia...&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Como os governos NÃO investem em educação de qualidade, a educação pública leva desvantagem clara na disputa de vestibulares de quaisquer naturezas. O CORRETO seria aprimorar a educação pública para que os alunos obtivessem melhor resultados.&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;span style=&quot;color: #323333; font-size: 15px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;
&lt;span style=&quot;color: #323333; font-size: 15px;&quot;&gt;&lt;/span&gt;&lt;/span&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;span style=&quot;color: #323333; font-size: 15px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;span style=&quot;color: #323333; font-size: 15px;&quot;&gt;
&lt;div style=&quot;text-align: justify;&quot;&gt;
Mas isso seria o ÓBVIO e o ÓBVIO NÃO TRÁZ VOTOS !!!&amp;nbsp;&lt;/div&gt;
&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Obviamente os políticos não irão fazer isso e preferem colocar alunos, por vezes menos qualificados, dentro das faculdades e universidades.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Sabe o que isso significa ?!&amp;nbsp; Que muitos alunos que vão entrar, não concluirão os cursos escolhidos.&amp;nbsp;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Sabe o que isso significa ?! Que vagas ociosas poderiam estar sendo mais bem aproveitadas e com um detalhe, mesmo as vagas ociosas geram custos a instituição de ensino, logo nossos altos impostos vão literalmente para o ralo.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Não quero menosprezar ou diminuir os alunos de instituições públicas, mas não se iludam com essa apelação política clássica em anos eleitorais.&amp;nbsp; Se a educação das escolas públicas fossem boas, seus alunos chegariam em igualdade de condições na disputa dos vestibulares e essas “coisas” de COTAS seriam apenas para comprar uma lembrancinha para os professores !!!&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; min-height: 17px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Uma educação de qualidade não começa na universidade, começa na alfabetização. Reflita e veja que essa imposição política é nociva a educação brasileira e que a médio ou longo prazo será desastroso.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;color: #323333; font-size: 15px; margin-bottom: 10px; text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Diga não ao sistema de cota, diga não a politicagem na educação...&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;2. Uma fonte de energia que não agride o ambiente, é totalmente segura e usa um tipo de matéria-prima infinita é a energia eólica, que gera eletricidade a partir da força dos ventos. O Brasil é um país privilegiado por ter o tipo de ventilação necessária para produzi-la. Todavia, ela é a menos usada na matriz energética brasileira. O Ministério de Minas e Energia estima que as turbinas eólicas produzam apenas 0,25% da energia consumida no país. Isso ocorre porque ela compete com uma usina mais barata e eficiente: a hidrelétrica, que responde por 80% da energia do Brasil. O investimento para se construir uma hidrelétrica é de aproximadamente US$ 100 por quilowatt. Os parques eólicos exigem investimento de cerca de US$ 2 mil por quilowatt e a construção de uma usina nuclear, de aproximadamente US$ 6 mil&amp;nbsp; por&amp;nbsp; quilowatt.&amp;nbsp; Instalados&amp;nbsp; os&amp;nbsp; parques,&amp;nbsp; a&amp;nbsp; energia&amp;nbsp; dos&amp;nbsp; ventos&amp;nbsp; é&amp;nbsp; bastante&amp;nbsp; competitiva, custando&amp;nbsp; R$&amp;nbsp; 200,00&amp;nbsp; por&amp;nbsp; megawatt-hora&amp;nbsp; frente&amp;nbsp; a&amp;nbsp; R$&amp;nbsp; 150,00&amp;nbsp; por&amp;nbsp; megawatt-hora &amp;nbsp; das hidrelétricas e a R$ 600,00 por megawatt-hora das termelétricas.&lt;/span&gt;&lt;/div&gt;

&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;De acordo com o texto, entre as razões que contribuem para a menor participação da energia eólica na matriz energética brasileira, inclui-se o fato de&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;A) haver, no país, baixa disponibilidade de ventos que podem gerar energia elétrica.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;B) o investimento por quilowatt exigido para a construção de parques eólicos ser de aproximadamente 20 vezes o necessário para a construção de hidrelétricas.&lt;/span&gt;&lt;/div&gt;

&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;D) o custo médio por megawatt-hora de energia obtida após instalação de parques eólicos ser igual a 1,2 multiplicado pelo custo médio do megawatt-hora obtido das hidrelétricas.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;

&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;3. A energia geotérmica tem sua origem no núcleo derretido da Terra, onde as temperaturas atingem 4.000 ºC. Essa energia é primeiramente produzida pela decomposição de materiais radiativos dentro do planeta. Em fontes geotérmicas, a água, aprisionada em um reservatório subterrâneo, é aquecida pelas rochas ao redor e fica submetida a altas pressões, podendo atingir temperaturas de até 370 ºC sem entrar em ebulição. Ao ser liberada na superfície, à pressão ambiente, ela se vaporiza e se resfria, formando fontes ou gêiseres. O vapor de poços geotérmicos é separado da água e é utilizado no funcionamento de turbinas para gerar eletricidade.&amp;nbsp; A água quente pode ser utilizada&amp;nbsp; para aquecimento&amp;nbsp; direto ou em usinas de dessalinização.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;5. As pressões ambientais pela redução na emissão de gás estufa, somadas ao anseio pela diminuição da dependência do petróleo, fizeram os olhos do mundo se voltarem para os combustíveis renováveis, principalmente para o etanol. Líderes na produção e no consumo de etanol, Brasil e Estados Unidos da América (EUA) produziram, juntos, cerca de 35 bilhões de litros do produto em 2006. Os EUA utilizam o milho como matéria-prima para a produção desse álcool, ao passo que o Brasil utiliza a cana-de-açúcar. O quadro abaixo apresenta alguns índices relativos ao processo de obtenção de álcool nesses dois países.&lt;/span&gt;&lt;/div&gt;

&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Se comparado com o uso do milho como matéria-prima na obtenção do etanol, o uso da cana-de- açúcar é&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;A) mais eficiente, pois a produtividade do canavial é maior que a do milharal, superando-a em mais do dobro de litros de álcool produzido por hectare.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;

&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;C) igualmente eficiente, pois, nas duas situações, as diferenças entre o preço de venda do litro do álcool e o custo de sua produção se equiparam.&lt;/span&gt;&lt;/div&gt;
&lt;div style=&quot;margin-bottom: 10px;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;D) menos eficiente, pois o balanço energético para se produzir o etanol a partir da cana é menor que o balanço energético para produzi-lo a partir do milho.&lt;/span&gt;&lt;/div&gt;

 manhã, com temperatura de 10 ºC, João encheu completamente o tanque de

&lt;b&gt;&lt;span style=&quot;font-size: small;&quot;&gt;Aquecimento
global
refere-se
ao aumento
da temperatura média dos oceanos e do
ar perto da
superfície
da Terra que se tem verificado nas décadas mais recentes e sua
possível continuação durante
o século XXI. O clima marítimo depende da temperatura dos oceanos
nos trópicos e este está em
equilíbrio com a velocidade de evaporação da água e com a
radiação solar que atinge a Terra. A principal
evidência do aquecimento global vem das medidas de temperatura em
todo o globo desde 1860.
Os dados com a correção dos efeitos de “ilhas urbanas” mostram
que o aumento médio da temperatura foi de (0.6 + 0.2) °C durante o
século XX. Os maiores aumentos foram observados em dois períodos:
1910 a 1945 e 1976 a 2000. De 1945 a 1976, houve uma diminuição da
temperatura global
que fez com que temporariamente a comunidade científica suspeitasse
que estava ocorrendo um
resfriamento global. O grande responsável pelo aquecimento é a
queima de combustível fóssil. Cada
tonelada de carvão consumida em usinas de geração de energia
elétrica produz cerca de 2.000 KWh.&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;

Um objeto é colocado perpendicularmente ao eixo principal de um espelho esférico
convexo. Notamos que, nesse caso, a altura de imagem é i&lt;sub&gt;1&lt;/sub&gt;. Em
seguida, o mesmo objeto é aproximado do&amp;nbsp;espelho,&amp;nbsp;formando uma nova
imagem, cuja altura é i&lt;sub&gt;2&lt;/sub&gt;. Quando aproximamos o objeto, a
imagem:&amp;nbsp;&lt;o:p&gt;&lt;/o:p&gt;&lt;/div&gt;
