An all-electric home uses approximately 2 000 kWh of electric energy per month. How much uranium would be required to provide this house with its energy needs for one year ? Assume 100% conversion efficiency and 208 MeV released per fission.
An all-electric home uses approximately 1910 kWh of electric energy per month. How much uranium-235 would be required to provide this house with its energy needs for one year? Assume 100% conversion efficiency and 208 MeV released per fission.
An electric car drives 40 miles, depleting its battery of 10 kWh of energy. It is charged by plugging into an outlet that draws its power from a natural-gas-burning power plant that has an efficiency of 35%. How much primary energy in kWh of natural gas was used to provide the 10 kWh of energy for the car's battery? Provide your answer to 3 significant figures.
An electric water heater holds 202 L. If electricity costs 0.13 $ per kWh, how much does it cost to raise the water temperature from 20 ∘C to 90 ∘C?
The average US citizen consumes 12000 kWh of electric energy per year an ‘ end use’ number and does not include the energy lost in converting other energy sources, e.g. fossil fuels to electricity. Note also that a kWh (kilowatt hour) is a unit of energy (not power) but a ‘kWh per year’ is a unit of power. The average electric bill indicates that a consumer pays about $0.12 per kWh of electric energy. Your Uncle Joe wants to get...
How much energy is required to accelerate a spaceship with a rest mass of 139 metric tons to a speed of 0.528 c? Hints: In the acceleration process the energy we have is converted to the kinetic energy of the spaceship. The classical kinetic energy of an object is half of the mass multiplied by the square of the velocity. What is the relativistic form of the kinetic energy? Incorrect. Tries 1/20 Previous Tries Every day our Earth receives 1.55×1022...
