Tom and Mary are at a playground that has two merry-go-rounds. Merry-go-round ‘A’ has a radius 1/3 as long as merry-go-round ‘B’. Tom gets on the outer rim of A and Mary on the outer of B and both begin to rotate their merry-go-rounds. Eventually Tom notices that every time he completes a revolution, Mary also completes a revolutio

Tungsten-filament lightbulb emits light based on the temperature of the filament. which phenomenon does this demonstrate?

Give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
