On a cold, winter day, Sheena rubs her hands together to warm them up. How could Sheena actions be used to explain the Law of Conservation of Energy?

If an area has high air pressure and low humidity, what type of weather will it most likely have? plz !

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?

How do you know when a chemical reaction has occurred
