Not a "number." Energy is the speed of light squared times mass, so E = mc2.

What number represent e equals mc2?

no number E=energy m=mass and c=speed of light squared


What does e equals mc2 stand for?

Energy equals mass multiplied by the speed of light squared


Who discovered the equation energy times speed of light squared?

Einstein


What does e plus mc squared mean?

E=MC2 means that energy is equal to mass times the speed of light squared E=Energy M=Mass C=Speed of Light E+MC2 mean Energy+(Mass*Speed of Light)2 (squared) (This is using Albert Einstein's theory of what M,C and E means.


Can you simplify EMC2?

E=energy. M=mass. C=speed of light in a vacuum. 2= squared the equation to make it multiply to the specified number it was originated to. energy= mass x speed of light squared. mass on earth= 9.8 m / s. speed of light= 299 792 458 m / s. squared that= 8631644736588396614.56 m / s. mass on earth= 9.8 m / s. x speed of light= 299 792 458 m / s. ÷ squared that= 8631644736588396614.56 =3.4037152571240005058732317803563e-10 In natural units, where the speed of light is defined to be 1, the equation simplifies to E = m.


Speed of light squared?

That is used as a conversion factor between mass and energy.


What do you mean by E mc?

E stands for energy, M for mass, and C squared for the speed of light squared.


What is e plus cm2?

E=cm2 is Energy = speed of light + mass squared.


What did albert stand for emc2?

Energy equals mass times the SPEED of light squared


What was einsten's energy equation?

e=mc^2 energy is equal to (mass) times (the speed of light squared)


What dos Emc2 mean?

Energy equals mass times the speed of light squared. Energy and mass are equivalent.


Why is mass multiplied by the speed of light squared in Einsteins famous equation?

Einstein's famous equation E=mc^2 represents the equivalence of energy and mass. When mass is converted into energy, the speed of light squared (c^2) is used as a conversion factor to illustrate the vast amount of energy that can be produced even from a small amount of mass.
