Percentage error = Value experimental-Value acceptedValueaccepted x 100

E = mc^2

this scientific equation is used to describe how a small amount of mass or matter can release a huge amount of energy. now in this equation e means energy while m means mass and c2 means speed of light 2

density = mass/volume

Because. The variable M is already used in an equation for mass.

A specific calculation is used to calculate concentricity. C = Wmin / Wmax x 100 percent. In this equation, Wmin equals the minimum width and Wmax equals the maximum width.

E = mc2 is used to calculate how much energy is produced when you convert matter to energy. The variables stand for E = Energy, m = mass, and c = speed of light. If you do the math correctly, you will see that a very small amount of mass will generate a very large amount of energy. The equation can be used to calculate the energy of an atomic bomb or a nuclear power plant where mass and energy are converted.
