Calculate the minimum intensity of light in watts (j/s) required to eject 1.40 x 1011 electrons (each with a kinetic energy of 3.61 x 10-19 j) using a 0.20 second pulse of light.

In a set amount of time, a battery supplies 25j of energy to an electric circuit that includes two different loads. one of the loads produces 10 j of heat energy during this time interval. how much heat energy is produced by the second load in this time? explain your answer
