On a summer day, 175 000 joules of energy are supplied to this electric aircraft's solar cells every second. The useful energy transferred by the solar cells is 35 000 joules every second.
Calculate the efficiency of the solar cells.

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
