sound
energy
reactions
matter

Answer 1

Albert Einstein discovered the mathematical relationship between energy and matter. 

Answer 2

Energy and matter

Step-by-step explanation:

Equivalence between energy and matter (mass) is given by:

`E=mc^2`

It establishes that the equivalent energy of an object can be calculated as the product of its mass times speed of light. Given that the speed of light is a very big number, the formula implies that even a small object at rest contains a very high amount of energy.
