Calculate the efficiency for each machine, then answer the question. Machine A has an input work of 1,000 J and an output work of 250 J.

Machine B has an input work of 500 J and an output work of 350 J.

Machine C has an input work of 200 J and an output work of 150 J.

in physics zero. in muscle fatigue could be high

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
