If you were on the moon, and you were trying to move a 20-lb bowling ball and a 3-foot cube of Styrofoam, which item would take more work to move? Why?

The 20 lb bowling ball would take more work to move. This is because it has more mass

Explanation:

It is the bowling ball that will take more work to move. The reason for this is simple. Mass is constant anywhere, whether it is on the moon or on the earth.

It is the acceleration due to gravity that is different in both places. Work as we all know is a factor of mass, the higher the mass, the more work it will take to displace the mass from its position.

Thus, because the mass of the bowling ball is greater, it will take more work to move than the styrofoam

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
