12. An athlete applies a force to a wall and becomes exhausted . Was there any work done? a. Yes, the wall moved b. Yes, the athlete became exhausted c. No, the wall did not move d. No, the athlete became exhausted

## Step 1: Define Work in Physics### Work is defined as the product of force and the distance over which it is applied in the direction of the force, mathematically: .## Step 2: Determine if Work was Done### For work to be done, there must be a displacement in the direction of the force. If the wall did not move, displacement is zero.## Step 3: Relate Exhaustion to Work### Exhaustion of the athlete indicates energy expenditure but not necessarily work in the physics sense, as work requires displacement.
