In an ideal pulley system, a woman lifts a 100-n crate by pulling a rope downward with a force of 25 n. for every one-meter length of rope she pulls downward, the crate rises

We can use conservation of energy to solve this question. The woman increases the potential energy of the box by applying her force over a certain distance. The work that the woman does is force * distance. The work the woman does is 25 N * 1 meters = 25 Joules. 25 Joules is the increase in potential energy of the box. 100 * distance of the box = 25 distance of the box = 0.25 meters Therefore, for every one meter the woman pulls downward, the box rises a distance of 0.25 meters.

Did you ever figue this

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .
