a. a mechanical advantage of less than 1 results.
b. the directions of input and output forces must be the same.
c. the amount of work that is done is decreased.
d. the input force is exerted over a larger distance than the output force.

In a system, when potential energy decreases, then entropy also decreases. true false

Agas expands from an initial volume of 0.040 m^3 and an initial pressure of 210 kpa to a final volume of 0.065 m^3 while its temperature is kept constant. how much work is done by the system?
