If the wavelengths or light absorbed by hydrogen and helium are shifted toward the red end of the spectrum, are those wavelengths becoming shorter or longer? Explain

Easy definition for atom and atomic mass

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

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?
