(Dear you can't delete this question caue its about school work too) (Flair?) I failed my siecne mindterm with a 50%, can pass that class? (My total grade is a 90.5%)

This classification of drug typically changes the brain's chemistry and reduces its ability to create its own endorphins.

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?
