The armature in an electric generator is rotating at the rate of 95 revolutions per second (rps). If the maximum voltage produced is 315 V, find an equation that describes this variation in voltage. (Let E be the voltage and let t be the time in seconds. Assume that when t

Aman pushes on a trunk with a force of 250 newtons. the trunk does not move. how much positive work is done on the trunk? 0.0 j -250 j 250 j 125 j

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final
