How does thermal energy transfer when a room is heated by a furnace? a)hot air is absorbed by the objects in the room; cold air expands and rises. b) hot air is circulated through the room; the hot air rises, and cold air falls. c) hot air makes direct physical contact with the objects in the room and rises. d) hot air is transmitted by electromagnetic waves; the hot air rises and falls.

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?
