the united states navy diving manual contains a wealth of information about diving from the history of diving to underwater physics and physiology. start by browsing the u. s. navy diving manual and then post a response to the following questions: how do the pressure variations with depth affect our ability to explore the ocean? what are some of the challenges of scuba diving?

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?
