Aray of light strikes a flat block of glass (n = 1.50) of thickness 3.00 cm at an angle of 32.0° with the normal. trace the light beam through the glass, and find the angles of incidence and refraction at each surface. if the angle of incidence at first surface is 32.0° (all angles are measured from the normal), determine the following angles.

How much work would it take to move a coulomb charge across a 4 volt potential difference?

The molecular mass of a gas is (select all that apply) a. independent of the type of gas b. the same number as the atomic (or molecular) mass, but measured in grams c. dependent on the temperature d. the mass of a mole of the gas
