Objects in motion of kinetic energy an object fall their potential energy is converted into kinetic energy how much kinetic energy do you think the ball will have just before i hit the floor as if it was dropped from a 2 meter shelf

Ultraviolet radiation is dangerous because it has a high enough energy to damage skin cells. what is the best explanation of the relationship between wavelength and wave energy? a) wave energy is related only to frequency, not wavelength. b) longer wavelengths have lower frequencies but higher energy. c) the shorter the wavelength, the lower the frequency and the higher the energy. d) the shorter the wavelength, the higher the frequency and the higher the energy.
