(EsPCEx - 2016) No ano de 2014, os alunos da EsPCEx realizaram um experimento de eletrlise durante uma aula prtica no Laboratrio de Qumica. Nesse experimento, foi montado um banho eletroltico, cujo objetivo era o depsito de cobre metlico sobre um clipe de papel, usando no banho eletroltico uma soluo aquosade sulfato de cobre II. Nesse sistema de eletrlise, por meio de uma fonte externa, foi aplicada uma corrente constante de 100 mA, durante 5 minutos. Aps esse tempo, a massa aproximada de cobre depositada sobre a superfcie do clipe foi de: Dados: massa molar Cu = 64 g/mol; 1Faraday = 96.500 C.

(EsPCEx - 2016) Leia o texto a seguir e responda s questes 48, 49 e 50. How Brazil Crowdsourced a Pioneering Law The passage of the Marco Civil da Internet, an Internet bill of rights commonly referred to in English as the Brazilian Civil Rights Framework for the Internet, demonstrates how the Internet can be used to rejuvenate democratic governance in the digital age. The law is important not only for its content, but for the innovative and participatory way it was written, bypassing traditional modes of legislation-making to go directly to the countrys citizens. At a moment when governments of all kinds are viewed as increasingly distant from ordinary people, Brazils example makes an argument that democracy offers a way forward. The pioneering law was signed in 2014 and has three components. First, it safeguards privacy by restricting the ability of private corporations and the government to store Internet users browsing histories. Second, it mandates a judicial review of requests to remove potentially offensive or illegal material, including content that infringes copyrights. And third, it prohibits Internet service providers from manipulating data transfer speeds for commercial purposes. The bill was acclaimed by activists as an example the rest of the world should follow. What makes this law even more interesting is that it became one of the largest-ever experiments in crowdsourcing legislation. The laws original text was written through a website that allowed individual citizens and organizations including NGOs, businesses, and political parties to interact with one another and publicly debate the laws content. This process was markedly different from the traditional method of writing bills behind closed doors in the halls of Congress, a process that favored well-connected families and large corporations. Policymakers in other countries have tried to capture citizen input using social media before, but never on this scale, in a country of roughly 200 million people. Whether it would succeed was far from certain. During the websites public launch, in 2009, one of the government lawyers summed up the organizers high hopes: This experience could transform the way we discuss not just legislation about the Internet, but also the way we discuss other bills in Brazil, and, in so doing, reconfigure our democracy. Adapted from http://foreignpolicy.com/2016/01/19/how-brazil-crowdsourced-a-landmark-law/ Choose the alternative that correctly substitutes the word bypassing in the sentence ... bypassing traditional modes of legislation-making ... (paragraph 1).

(EsPCEx - 2016) Operation Desert Storm Was Not Won By Smart Weaponry Alone Technology has long been a deciding factor on the battlefield, from powerful artillery to new weaponry to innovations in the seas and the skies. Twenty-five years ago, it was no different, as the United States and its allies proved overwhelmingly successful in the Persian Gulf War. A coalition of U.S. Army Apache attack helicopters, cruise missiles from naval vessels, and Lockheed F-117 Nighthawk stealth fighters soundly broke through Saddam Husseins army defenses in Kuwait during Operation Desert Storm, which became known as the 100-hour war. But for all the possibilities that this Computer War offered, Operation Desert Storm was not won by smart weaponry, alone. Despite the science fiction-like technology deployed, 90 percent of the pieces of ammunition used in Desert Storm were actually dumb weapons. The bombs, which werent guided by lasers or satellites, were lucky to get within half a kilometer of their targets after they were dumped from planes. While dumb bombs might not have been exciting enough to make the headlines during the attack, they were cheaper to produce and could be counted on to work. But frequency of use doesnt change why history will remember Desert Storm for its smart weapons, rather than its dumb ones. Adapted from http://www.smithsonianmag.com/history/operation-desert-storm-was-not-won-smart-weaponry-alone-180957879/ Choose the alternative that has the sentence Operation Desert Storm was not won by smart weaponry (paragraph 2) correctly changed into active voice.
