The United States uses approximately 3.0 trillion kWh of electricity annually. If 20% of this electrical energy were supplied by nuclear generating plants, how much nuclear mass would have to be converted to energy, assuming a production efficiency of 25%?
Answer to relevant QuestionsTo travel to a nearby star, a spaceship travels at 0.99c to take advantage of time dilation. If the ship has a mass of 3.0 x 106 kg, how much work must be done to get it up to speed from rest? Compare this value with the ...A proton moving with a constant speed has a total energy 3.5 times its rest energy. What are the proton’s (a) Speed, (b) Kinetic energy, and (c) Momentum? In Exercise 37, what would be the acceleration due to gravity at a distance of two Schwarzschild radii from the center of the “black hole” Sun? Compare your answer to the actual gravitational acceleration at a distance ...A rocket launched outward from Earth has a speed of 0.100c relative to Earth. The rocket is directed toward an incoming meteor that may hit the planet. If the meteor moves with a speed of 0.250c relative to the rocket and ...At a typical nuclear power plant, refueling occurs about every 18 months. Assuming that a plant has operated continuously since the last refueling and produces 1.2 GW of electric power at an efficiency of , how much less ...
