The side of the base of a square prism is increasing at a rate of 555 meters per second and the height of the prism is decreasing at a rate of 222 meters per second. At a certain instant, the base side is 666 meters and the height is 777 meters. What is the rate of change of the volume of the prism at that instant (in cubic meters per second)

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?
