A900-w microwave generator in an oven generates energy quanta of frequency 2560 mhz. (a) how many energy quanta does it emit per second? (b) how many energy quanta must be absorbed by a pasta dish placed in the radiation cavity to increase its temperature by 45.0 k? assume that the dish has a mass of 0.5 kg and that its specific heat is 0.9kcal/kgâ‹…k. (c) assume that all energy quanta emitted by the generator are absorbed by the pasta dish. how long must we wait until the dish in (b) is ready?

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
