Answer 2

To calculate the work done by a force, we can use the formula:

Work = Force x Distance

In this case, we are given that a vertical force of 25 N is applied to the long arm of a lever, and it lifts a load of 20 kg suspended from the short arm of the lever. We need to find the work done by the force applied to the long arm of the lever.

To calculate the work done, we need to determine the distance over which the force is applied. In this case, the distance is given as 5 cm (0.05 m).

Using the formula, we can calculate the work done as follows:

Work = Force x Distance = 25 N x 0.05 m = 1.25 J

Therefore, the work done by the force applied to the long arm of the lever is 1.25 Joules (J).
