The change in mass of fuel during a nuclear reaction is 2.0 x 10-27 kg. Calculate the amount of energy released. (Speed of light = 2.0 x 108ms-1)

The change in mass of fuel during a nuclear reaction is 2.0 x 10^-27 kg. Calculate the amount of energy released. (Speed of light = 2.0 x 10⁸ms^-1)

Answer Details

The equation that relates mass and energy is E=mc². Here, the change in mass is given as 2.0 x 10^-27 kg. The speed of light is given as 2.0 x 10⁸ ms^-1. Substituting these values in the equation, we get: E = (2.0 x 10^-27 kg) x (2.0 x 10⁸ ms^-1)² E = 1.8 x 10^-10 J Therefore, the amount of energy released is 1.8 x 10^-10 J.
