Plants and animals that share a often help each other survive. Plants provide food and shelter for animals. In turn, animals help plants reproduce. When bees and other insects gatherthey also carryfrom flower to flower. This helps tothe flowers. The of each flower then produces seeds and grows into a fruit. Other animals scatter the seeds.

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?
