An egg is thrown upward with an initial speed of 4 m/s. After 6 seconds, the eggs velocity is m/s A -43 B-60.8 C -38.4 D -54.8 E -29.2

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?
