(FUVEST - 2022 - 1 fase) Fatbergs are a growing scourge infesting cities around the world some are more than 800 feet long and weigh more than four humpback whales. These gross globs, which can cause sewer systems to block up and even overflow, have been plaguing the U.S., Great Britain and Australia for the past decade, forcing governments and utilities companies to send workers down into the sewers armed with water hoses, vacuums and scrapers with the unenviable task of prying them loose. It is hard not to think of [fatbergs] as a tangible symbol of the way we live now, the ultimate product of our disposable, out of sight, out of mind culture, wrote journalist Tim Adams in The Guardian. At their core, fatbergs are the accumulation of oil and grease thats been poured down the drain, congealing around flushed nonbiological waste like tampons, condoms and baby wipes. When fat sticks to the side of sewage pipes, the wipes and other detritus get stuck, accumulating layer upon layer of gunk in a sort of slimy snowball effect. Fatbergs also collect other kinds of debrisLondon fatbergs have been cracked open to reveal pens, false teeth and even watches. Restaurants are a big contributor to fatbergs: Thames Water, the London utilities company, found nine out of 10 fast-food eateries lacked adequate grease traps to stop fat from entering the sewers. Homeowners also contribute to the problem by pouring grease and fat down the sink. Even though its component materials are soft, fatbergs themselves can be tough as rocks. Researchers have found a host of dangerous bacteria in fatbergs, including listeria and e.coli. Fatbergs are notorious for their fetid smell, which can make even the hardiest sewer workers gag, and chipping away at one can release noxious gases. The key to fatberg prevention is remembering the four Ps: Pee, poo, puke and (toilet) paper are the only things that should be flushed. Newsweek, 14 March, 2019. Adaptado. Considerado o contexto, os quatro elementos associados preveno dos fatbergs tm em comum o fato de

(FUVEST - 2022 - 1 fase) If you take a look at my smartphone, youll know that I like to order out. But am I helping the small local businesses? You would think that if you own a restaurant youd be thrilled to have an outsourced service that would take care of your delivery operations while leveraging their marketing might to expand your businesses brand. However, restaurant owners have complained of lack of quality control once their food goes out the door. They dont like that the delivery people are the face of their product when it gets into the customers hand. Some of the delivery services have been accused of listing restaurants on their apps without the owners permission, and oftentimes publish menu items and prices that are incorrect or out of date. But there is another reason why restaurant owners arent fond of delivery services. Its the costs, which, for some, are becoming unsustainable. Even with the increased revenues from the delivery services, the fees wind up killing a restaurants margins to the extent that its at best marginally profitable. Therefore, some restaurants are pushing harder to drive orders from their own websites and offering special deals for customers that use their in-house delivery people. The simple fact is that these delivery apps are here to stay. They are enormously popular and have significantly grown. I believe that restaurant owners that resist these apps are hurting their brands by missing out on potential customers. The good news is that the delivery platforms are not as evil as some would portray them. They have some skin in the game. They are competing against other services. They want their listed restaurants to profit. Maybe instead of fighting, the nations restaurant industry needs to proactively embrace the delivery service industry and figure out ways to profitably work together. The Guardian. 02 December, 2020.

(FUVEST- 2022 - 1 fase) O canho de Newton, esquematizado na figura, um experimento mental imaginado por Isaac Newton para mostrar que sua lei da gravitao era universal. Disparando o canho horizontalmente do alto de uma montanha, a bala cairia na Terra em virtude da fora da gravidade. Com uma maior velocidade inicial, a bala iria mais longe antes de retornar Terra. Com a velocidade certa, o projtil daria uma volta completa em torno da Terra, sempre caindo sob ao da gravidade, mas nunca alcanando a Terra. Newton concluiu que esse movimento orbital seria da mesma natureza do movimento da Lua em torno da Terra. Qual deveria ser a velocidade inicial de um projtil lanado horizontalmente do alto do Everest (a uma distncia aproximada de 6.400 km do centro da Terra) para coloc-lo em rbita em torno da Terra?

Supondo que essa velocidade tivesse sido constante ao longo do tempo, e tomando uma distncia atual de cerca de 5.000 km entre os limites dessas duas massas continentais, indique a melhor estimativa para quanto tempo teria transcorrido desde quando ambas estavam unidas em um nico supercontinente.

(FUVEST - 2022 - 1 fase) Uma mancha de petrleo com mais de 3000 km de extenso se espalhou por praias e manguezais da costa da regio nordeste e parte do sudeste, atingindo reas marinhas protegidas como o Parque Nacional Marinho de Abrolhos, um dos principais bancos de corais e bero de biodiversidade do Atlntico Sul. Desde que foi detectada pela primeira vez, no dia 30 de agosto de 2019, a mancha de petrleo atingiu cerca de 900 locais em mais de 127 municpios em 11 estados. A origem do petrleo est estimada em algum local a leste do litoral do estado de Pernambuco, distante, aproximadamente, 600 km da linha de costa. Disponvel em https://www.wwf.org.br/. 2019. Adaptado. Com base em seus conhecimentos sobre o litoral brasileiro e as correntes martimas superficiais que margeiam a costa, assinale a alternativa correta que aponta o fator que contribuiu para a disperso do petrleo.
