The average kinetic energy of the molecules in a gas sample depends only on the temperature, t. but given the same kinetic energies, a lighter molecule will move faster than a heavier molecule. what is the rms speed of o2 molecules at 423 k?

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
