When using a pulley, the mechanical advantage allows you to lift a weight with less force, but you have to pull over a greater distance. In this scenario, if lifting the weight without a pulley requires a force of 400 newtons over a distance of 4 meters, applying the pulley would typically lead to a reduction in the force required to lift the weight, while the distance you need to pull the rope increases.
Thus, the correct response is: **The force decreases, while the distance increases.**
Thus, the correct response is: **The force decreases, while the distance increases.**
