A nuclear power plant can produce large amounts of power by harnessing the heat produced by nuclear fission. That heat boils water, and the steam spins a turbine connected to a generator which produces an electrical current. This is a very simplified version of what happens, but you get the idea. If this power plant can produce 104 TJ (terajoules) of energy in one day. a. What is the power rating of the plant? (5 points) If you're not familiar with that prefix, see the back of your formula sheet. They are all there. b. If the plant can sell electrical energy at $0.15 per kilowatt-hour, how much money can they make in a day? (5 points) 4. Gravitational Potential energy Sputnik had a mass of about 84 kg. Calculate its total mechanical energy if it orbited at an altitude of 940 km above Earth's surface. Earth's radius is 6380 km and its mass is 5.98 x 1024 kg. a. Find Sputnik's orbital speed (4 points) b. Find Sputnik's total mechanical energy (6 points)
