Acircular loop with a 0.03-m radius and 18-ω resistance is facing away from this page. a magnetic field that points into the page was 0.35 t one second ago and is now 0.25 t. what current (in which sense of circulation) appears in this loop, if any?

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
