It is not from thermodynamic energy?
prohojiy [21]

Answer:

(a) Utilization

Explanation:

Thermodynamic energy are:

<h2>(1) Kinetic energy:</h2>

Kinetic energy is that type of energy of a body which occurs due to the motion of body. Kinetic energy is always positive. In a bound system, the system remains bound as long as the kinetic energy is less than the potential energy due to the interaction of the body.

                            K.E = \frac{1}{2}mv^{2}

<h2>(2) Potential energy:</h2>

Potential energy is defined as the energy in which the energy is possessed by a body or a system for doing some work, by virtue of its position above the ground level.

Therefore,

Potential energy = PE = mgh

This potential energy is a result of gravity pulling downwards. The gravitational constant, g, is the acceleration of an object due to gravity. This acceleration is about 9.8 m s⁻².

<h2>(3) Stored energy:</h2>

Stored energy is a Potential energy.

Hence, the only energy which is not a thermodynamic energy is option (a) Utilization energy.
