Write the equation of mass-energy equivalence.
(N/A) The mass-energy equivalence principle,proposed by Albert Einstein,states that mass and energy are interchangeable. The equation is given by: $E = mc^2$,where $E$ is the energy,$m$ is the mass,and $c$ is the speed of light in a vacuum $(c \approx 3 \times 10^8 \ m/s)$.
