To clarify the distinction between speed and velocity, and to review qualitatively one-dimensional kinematics. a woman stands at the edge of a cliff, holding one ball in each hand. at time t0, she throws one ball straight up with speed v0 and the other straight down, also with speed v0. for the following questions neglect air resistance. pay particular attention to whether the answer involves "absolute" quantities that have only magnitude (e. g., speed) or quantities that can have either sign (e. g., velocity). take upward to be the positive direction.

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.
