This is the answer, hope it helps :)
As you crank the variable resistor to higher resistance, the total current in the loop decreases. The power dissipated by the light bulb ... the heat and brightness it produces ... depend directly on the current through it, so they decrease too. Your circuit is a perfect incandescent light dimmer circuit.
Answer:
D ) Elastic and Gravitational
Explanation:
Mechanical energy is defined as the sum of elastic, potential and kinetic energies.
Therefore potential energy and gravitational or potential energy are contemplated within the definition of mechanical energy.

The units for energy are given in joules [J] for the SI and Btu for the IP system
