A rock is pushed out of a six-story window that is 60 feet above the ground. What energy changes occur as the rock falls to the ground? A) The potential energy of the rock is destroyed as it falls. B) The potential energy of the rock is transformed into kinetic energy. C) The kinetic energy of the rock is transformed into potential energy. D) The rock on the ground possesses more potential energy than it did when it was 60 feet higher.

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?
