Two wires are oriented perpendicular to each other. Wire 1 carries a current of 5.0 A upward, and Wire 2 carries a current of 7.5 A to the right. What is the magnitude and direction of the net magnetic field, if r1= r2 10 cm?

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
