Two ideal heat engines, A and B, operate on the difference of temperatures of hot and cold reservoirs 200 K. But engine A has temperature of cold reservoir 100K, and engine B has temperatures of hot reservoir 400K. Which of these two engines has greater theoretical efficiency

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
