C) is zero
According to the law of energy conservation, the total mechanical energy of the object is conserved. A book falling a distance d would have a change in potential energy, resulting in the same change in kinetic energy. But the total mechanical energy must be the same. So there's 0 change in total energy of the system.

Using a gas power heater to warm a room
In what ways are electromagnetic force and gravitational force similar
From looking at the two force equations, you can see the similarities and how gravitational force can be considered parallel to the force between two charges.
Besides being proportional to the inverse of the square of the separation: both forces extend to infinity,They also both travel at the speed of light.
