A 76-kg pilot at an air show performs a loop de loop with his plane. At the bottom of the 52-m radius loop,
the plane is moving at 48 m/s. Determine the
centripetal acceleration acting upon the pilot.

If 21.2 kcals of energy is released by this reaction, how many kj does the reaction release? (1 cal 4.184 j)

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
