The rest energy E of an object with rest mass m is given by Albert Einstein’s famous equation E = mc2, where c is the speed of light in vacuum. Find E for an electron for which (to three significant figures) m = 9.11 * 10^-31 kg. The SI unit for E is the joule (J); 1 J = 1 kg m2/s2. c = 2.99792458 * 10^8 m/s.
The sun produces energy by nuclear fusion reactions, in which matter is converted into energy. By measuring the amount of energy we receive from the sun, we know that it is producing energy at a rate of 3.8 * 1026 W. (a) How many kilograms of matter does the sun lose each second? Approximately how many tons of matter is this (1 ton = 2000 lb)? (b) At this rate, how long would it take the sun to use up all its mass?
