Answer 1

When a pulley is applied to lift a weight, the mechanical advantage allows you to lift the weight with less force. However, this typically requires pulling over a longer distance than you would without the pulley.

In this specific case:

• The force required to lift the weight decreases because the pulley helps distribute the weight and reduces the effort needed.
• The distance over which you must pull the rope to lift the weight increases because to lift the weight a certain distance, you have to pull the rope a longer distance.

Therefore, the correct response is:

The force decreases, while the distance increases.
