The atmosphere is full of nitrogen gas (N2). But plants cannot use nitrogen in this form. Summarize the roles of bacteria in making nitrogen available to plants and in returning nitrogen to the atmosphere.

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?

During the past 150 years in the united states, how did energy consumption compare to population growth
