$e = mc ^{2}$
ask with Albert Einstein and what he say that answer narrate me .
​

Answer 1

Answer:

Energy equals mass times the square of speed of light. On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same things

Answer 2

$\tt\huge{{E = mc^2}}$

where,

E = Energy(measured in joule)

m = mass(measured in kilogram)

c = speed of light(3x10^8m/s)

This formula was given by a world famous scientist, noble prize winner, Albert Einstein in the year 1905 which is the most famous formula in the world.
