A chunk of coal has a substantial amount of chemical potential energy. This image is courtesy of Oak Ridge National Laboratory. If released, the chemical potential energy will cause the coal atoms and molecules to vibrate violently, and this internal kinetic energy can be transferred to other nearby objects. Which of these is the best way to transform this chemical potential energy into internal kinetic energy? A. burn the coal B. drop the coal from a great height C. submerge the coal in water D. roll the coal down a hill

The ozone molecule o3 has a permanent dipole moment of 1.8Γ10β30 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 2.5Γ10β10 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?
