I need help with all three questions for this problem

The given force is:

Part A

If the displacement of the dog is:

d = (0.29m)x

The work done is the dot product of the force and displacement

Part B

If the displacement of the dog is:

d = (0.29m)y

The workdone will be calculated as:

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
