What is the velocity of a 15.0 kg mass if its kinetic energy is 3.50 x 103 J? a. 467 m/s b. 0.0926 m/s c. 21.6 m/s d. 2.17 x 105 m/s

What happens to the light rays when they hit the specimen?

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared
