the mean free path of an oxygen molecule is 2.0 x 10^-5 when the gas is at a pressure of 120 pa and a temperature of 275 k. The molecular mass of oxygen is 32.0 g/mol the average time interval between collisions of an oxygen molecule is closest to

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
