1. Segundo Platão, o que são as coisas verdadeiras e o que são as coisas falsas? 2. O que Sócrates está investigando neste trecho do livro? 3. Quem são os prisioneiros a qual Platão se refere? 4. Se pudéssemos colocar a situação narrada no livro VII por Sócrates nos dias atuais, quem seriam os prisioneiros? E quem seria o prisioneiro liberto? O que seria a Caverna? 5. Faça uma pesquisa sobre a biografia de Platão (Onde nasceu e viveu, que ano nasceu, que foi seu mestre, quais suas ideias, qual sua importância para o pensamento ocidental e outras questões que achar pertinente). 6. A partir de tudo que exploramos, que conclusão podemos tirar a respeito deste trecho do livro?

Modern physics a photon emitted from an excited hydrogen atom has an energy of 3.02 electron volts. which electron energy-level transition would produce this photon? a. n=1 to n=6 b. n=2 to n=6 c. n=6 to n=1 d. n=6 to n=2 i chose b but the correct answer is d can someone tell me why? and what's the difference?

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
