I can't decide between A and B, but B seems more likely to me. Even though the molecules don't look like they're moving, the area of contact is slightly more compressed.
It was D. Miguel Hidalgo but i could be wrong..
It will rise, and then fall back to the Earth’s surface.
Answer:
See the explanation below.
Explanation:
Work in physics is defined as the product of force by the distance that the body travels in the direction of the force.
It can be represented by means of the following equation.

where:
W = work [J]
F = force [N]
d = distance [m]
In the given example the work is zero since the tree does not move, therefore the bear exerts a force on the tree. But there is no talk of movement of the tree, therefore the work is zero.
