Our Sun shines bright with a luminosity of 3.828 x 1026 Watt. Her energy is responsible for many
processes and the habitable temperatures on the Earth that make our life possible.
(a) Calculate the amount of energy arriving on the Earth in a single day.
(b) To how many litres of heating oil (energy density: 37.3 x 106 J/litre) is this equivalent?
Our universe has properties that are determined by thevalues of the fundamental physical constants, and it would be a muchdifferent place if the charge of the electron, the mass of the proton, orthe speed of light was substantially different from its actual value. Forinstance, the speed of light is so great that the effects of relativity usuallygo unnoticed in everyday events. Let’s imagine an alternate universewhere the speed of light is 1,000,000 times less than it is in ouruniverse to see what would happen. In our universe, the rest energy of an electron is approximately 8.2 * 10-14 J. What would it be in the alternate universe? (a) 8.2 * 10-8 J; (b) 8.2 * 10-26 J; (c) 8.2 * 10-2 J; (d) 0.82 J.
