A hemorrhoidal ointment contains, on a weight-in-weight basis, 46.6% mineral oil, 1% pramoxine HCl, and 12.5% zinc oxide in an ointment base. Calculate the grams of each ingredient, including the ointment base, in each 30-g tube.

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?
