A person raises a box with a weight of 50 newton by 0.5 meter . How much work does the person do in this action

25 joules
0.0 joules
0.01 joules
100 joules

The work done by the person can be calculated using the formula:

Work = Force x Distance x cos(theta)

Where:
Force = 50 newtons
Distance = 0.5 meters
theta (angle between force and distance) = 0 degrees (assuming the force is being applied vertically)

Therefore, the work done by the person is:
Work = 50 newtons x 0.5 meters x cos(0) = 50 x 0.5 x 1 = 25 joules

So, the correct answer is 25 joules.
