The energy contained in a wire when it extended by 0.02m by a force 500 N is

This question involves calculating the energy contained in a wire that has been extended by a certain distance due to a force applied to it. The formula used to calculate the energy contained in a spring is given by: Energy = (1/2) * force * extension Where force is the applied force and extension is the distance the wire has been extended. Using the values given in the question, we have: Energy = (1/2) * 500 N * 0.02 m Energy = 5 J Therefore, the answer is 5J. Explanation: When a force is applied to a wire, it gets stretched or extended. The amount of extension in the wire is proportional to the force applied to it. The energy stored in the wire due to the applied force is given by the formula (1/2) * force * extension, where force is the applied force and extension is the distance the wire has been extended. In this case, the wire has been extended by 0.02 m due to an applied force of 500 N, so the energy contained in the wire is 5 J.
