Answer 1

Using a pulley typically decreases the amount of force needed to lift a weight, while the distance over which the force must be applied increases.

In this case, if lifting the weight without a pulley requires a force of 400 newtons over a distance of 4 meters, applying a pulley will reduce the required force (making it easier to lift the weight) but you will need to pull the rope over a greater distance to lift the weight the same height.

Therefore, the correct response is:

The force decreases, while the distance increases.
