Suppose you have a flashlight in your hand. describe the transformations of energy that take place to allow that flashlight to give off light. be sure to include where waste energy is given off.

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
