... (D) be essentially unaffected, since its main function--producing ordered work--is not dependent on disordered heat. Answer: (A) lose its ability to turn thermal energy into work. Why: As a heat engine, the car engine can only produce work out of heat by letting heat flow from hot to cold. If you sp ...

Motion in Two Dimensions
... Question: The graph below (not drawn to scale) shows the motion of tennis ball that was thrown vertically upwards from an open window some distance from the ground. It takes the ball 0,2 s to reach its highest point before falling back to the ground. Study the graph given and calculate 1. how high t ...

Work and Energy combined
... Well, the law of conservation of energy always works – it is the law, after all. What happens is that the energy of the ball is transformed into energy forms that do not contribute to the bounce height. We call these transformations energy losses. They are not really energy losses, however, in the ...
