Einstein's equation relating mass and energy is given by the formula E = mc, where m is the mass of an object and C = 3x108 ms-1, the speed of light.
1. Find how much energy is present in a 1 kg mass. (1 kg ms-1 = 1 joule)
2. Given that a standard light bulb uses 60 joules of energy every second, calculate how long (in years) such a light bulb could be powered by a 1 kg mass, if all the mass was converted to energy.
