Because the kinetic energy of a single molecule is related to its velocity squared, the best measure of the kinetic energy of the entire gas is obtained by computing the mean squared velocity, (v2)avg, or its square root vrms. the quantity vrms is more common than (v2)avg because it has the dimensions of velocity instead of the less-familiar velocity-squared. what is the rms speed vrms of the molecules in the nitrogen gas?

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?
