Ashark is swimming at 10 m/s west when it spots some floating bait caught in some seaweed straight ahead. after 10 s, and traveling at a velocity of 15 m/s, the shark reaches the bait. what was the shark's average acceleration? a. 0.5 m/s² b. 0.5 m/s² east c. 0.5 m/s² west d. 10 m/s²

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?
