How does temperature affect the formation of clouds?
A: Water vapor in the cool air condenses into tiny droplets of water, forming clouds.
B: Water vapor in the warm air condenses into tiny droplets of water, forming clouds.
C: Cool air combines with warm air to form clouds.
D: Water vapor in the cool air evaporates from the hydrosphere to form clouds.

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?
