Answer:
c is speed of light
Explanation:
Einstein's mass energy equivalence equation shows the relation between matter and energy. It can mathematically written as:
[tex]E=mc^2[/tex]
Where
E is the energy
m is the mass
c is speed of light.
Speed of light is a constant quantity. It is a universal constant.
Its value is equal to [tex]c=3\times 10^8\ m/s^2[/tex]
This equation shows that energy and mass are interchangeable quantities.
