Define atomic mass unit.
The unified atomic mass unit u is roughly equal to 1.66 × 10−27 kg which is the mass of one nucleon.
Calculate the mass, in kg, of a nucleus of uranium−238. Give your answer to 3 significant figures.
Einstein's Theory of Relativity showed that mass could be converted into energy, and energy into mass. This is summarised by the following equation
Define the terms in the equation and give the units
Calculate the energy released, in J, if all of the mass in the nucleus of uranium−238 were converted into energy.
