A conical tank has height 3 m and radius 2 m at the base. water flows in at a rate of 2 m3/min.

The law of the conservation of momentum says that the total momentum of any closed and isolated system cannot

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?

The strong nuclear force acts over a small distance than the electrostatic force. true or false
