Question

which two types of potential energies would be types of mechanical energies?
electrical and kinetic
nuclear and chemical
radiant and thermal
elastic and gravitational

Explanation:

Mechanical energy is the sum of kinetic energy and potential energy. Potential energy types that are mechanical include elastic (stored in stretched or compressed objects) and gravitational (due to an object's height in a gravitational field). Electrical, nuclear, chemical, radiant, and thermal are not mechanical potential energies. Kinetic is a form of mechanical energy but it is not potential energy.

Answer:

elastic and gravitational
