Explanation:
the branch of physical science that deals with the relations between heat and other forms of energy (such as mechanical, electrical, or chemical energy), and, by extension, of the relationships between all forms of energy
Answer:
<h3>

</h3><h3>
Explanation:</h3>
Let U1 and U2 be the gravitational potential energy of the first and second stone respectively.
U1 is given by:

and U2 is given by:
therefore, comparing the energies we have:

therefore:

Light is a <span>wave of vibrating electric and magnetic energy.</span>
