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 and potential energy. Potential energy types related to mechanical energy are elastic (stored in stretched or compressed objects) and gravitational (due to position in a gravitational field). Electrical, nuclear, chemical, radiant, thermal are not types of mechanical potential energy. Kinetic is a separate form (not potential) of mechanical energy.

Answer:

elastic and gravitational
