In Einstein’s famous equation E=MC2,E is energy, m is mass and c is the?
A
Current
B
Charge
C
Computer
D
Speed of light
Explanation: 

Detailed explanation-1: -According to Einstein’s equation E=mc2. E represents the rest mass energy of an object with rest mass m, c is the speed of light in vacuum, and is given by 2. 998×108sm.

Detailed explanation-2: -Einstein’s Big Idea homepage. E = mc2. It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

Detailed explanation-3: -“The conversion factor between space and time is light.” And the conversion factor between mass and energy is light, squared. We square the speed of light in Einstein’s formula for the same reason that we square the value for velocity in the equation for kinetic energy.

Detailed explanation-4: -The most famous equation in the world, E=mc2, arrived rather quietly. In 1905, Einstein published two articles on the Special Theory of Relativity.

Detailed explanation-5: -The formula E=mc2 states that the equivalent energy (E) can be calculated as the mass (m) multiplied by the speed of light (c = about 3×108 m/s) squared.
