How should you approach a dock when the wind or current is pushing you toward the dock? approach parallel to the dock and allow the wind or current to push you in. shut off the engine, and let momentum carry you head on toward the dock. approach as quickly as you can. then have someone jump to the dock to secure the bow line. back in with your bow pointed into the wind or current. then secure the stern line.

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?
