Based on the text below, answer questions 21, 22 and 23.

Inside The U.S. Navy's Leadership School


The top level of Navy leadership is its admirals . There are 238 of them. They have responsibility for more than 390, 000 members of the Navy and control an annual budget of more than $130 billion. They are the equivalent of a corporate C–suite. Of the more than 3,000 captains who serve in the Navy, roughly 38––barely 1% ––make the cut to admiral each year.
In 2001 the chief of naval operations––the Navy's CEO––asked retired Vice Admiral Phil Quast, who had spent 38 years in the Navy, to establish the program that became the Executive Learning Office. "Of 238 admiral positions, fewer than 40 are concerned with actual war fighting, " Quast notes. "The vast majority is doing jobs analogous to that of a CEO, CTO, CFO, COO or other functional business areas. Our job is to help them develop the business acumen they need to run the business of the Navy as excellent stewards of the public's money and its trust."

We suffer from historical amnesia.
Suppose you were born in 1900. You wouldn't yet watch movies, let alone global TV. Fewer than 10% of U.S. homes had phones, and fewer than 8% had electricity. Antibiotics hadn't been discovered. As yet the Internet isn't in the same league with these developments .
Each changed lifestyles and popular beliefs. The automobile suburbanized America and inaugurated mass travel. Antibiotics, vaccines and public–health advances helped raise life expectancy from 46 in 1900 to 77 today. The explosion of prosperity – a consequence of electricity, other technologies and modern management – shortened working hours and expanded leisure. Movies and TV transformed popular culture. As a matter of fact, the Internet is too young for anyone to foretell its ultimate significance.

The word "raise" in " (...) public–health advances helped raise life expectancy (...) ." means:

Based on the text below, answer questions 28 and 29.(( The turning tide for the turtles

With their exquisite shells, their smiling faces, their deliberate movements, and their amazing sea–born agility, sea turtles have always captured human imagination. Once severely endangered, turtle populations are growing steadily thanks to conservation projects worldwide. And with more than 8000 km of coastline, large stretches of which are favorite nesting spots for turtles, Brazil is one of the leaders in the race to protect them.

Dois pendulos constituídos por fios de massas desprezíveis e de comprimento L = 2,0 m estão pendurados em um teto em dois pontos próximos de tal modo que as esferas A e B, de raios desprezíveis, estejam muito próximas, sem se tocarem. As massas das esferas valem mA = 0,10 kg e mB = 0,15 kg. Abandona–se a esfera A quando o fio forma um ângulo de 60° com a vertical, estando a esfera B do outro pêndulo na posição de equilíbrio. Sabendo que, após a colisão frontal, a altura máxima alcançada pelo centro de massa do sistema, em relação à posição de equilíbrio, é de 0,40 m, o coeficiente de restituição da colisão é



Um bloco é solto de certa altura sobre uma mola ideal vertical que possui constante elástica K, como mostra a figura 1. O bloco passa a ficar preso à mola (despreze as perdas nesta colisão) comprimindo–a até parar momentaneamente. A figura 2 mostra o gráfico da Energia Cinética (E c)do sistema mola – bloco em função da deformação da mola (Y) . Sabe–se que E c é medida em joules e Y em metros. Analisando o gráfico, conclui–se que o valor da constante elástica K, em N/m, é
