Suppose that the average U.S. household uses 13100 kWh (kilowatt-hours) of energy in a year. If the average rate of energy consumed by the house was instead diverted to lift a 1470 kg car 12.3 m into the air, how long would it take? Using the same rate of energy consumption, how long would it take to lift a loaded 747, with a mass of 4.10 × 105 kg, to a cruising altitude of 9.92 km?
Suppose that the average U.S. household uses 14600 kWh (kilowatt-hours) of energy in a year.

Question 20 of 22 > Suppose that the average U.S. household uses 15600 kWh (kilowatt-hours) of energy in a year. If the average rate of energy consumed by the house was instead diverted to lift a 2240 kg car 11.3 m into the air, how long would it take? car: Using the same rate of energy consumption, how long would it take to lift a loaded Boeing 747 airplane, with a mass of 4.10 x 10 kg, to a cruising...
Energy consumption is measured in units of kilowatt hours (kWh). The more kWh a household use in a month, the higher the energy bill. A power company charges customers $0.12 per kWh for the first 500 kWh. After the first 500 kWh, the rate is $0.15 per kWh. Write a program to calculate energy charge. You must write and use the following two functions. (a) A main function: Ask the user to enter number of kWh used. Call the bill_calculator...
(3 pts) A power utility produces 500 g of CO2e per kWh of energy consumed. If using such a power facility to power up a computer, how much CO2e does the computer contribute during a year, assuming 240 working days annually and an average power of 30W during an 8-hour working day?
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...
A freezer has a coefficient of performance of 6.30. It is advertised as using 466 kWh/yr. Note: One kilowatt-hour (kWh) is an amount of energy equal to running a 1-kW appliance for one hour. (a) On average, how much energy does it use in a single day? J (b) On average, how much energy does it remove from the refrigerator in a single day? J (c) What maximum mass of water at 22.8°C could the freezer freeze in a single...
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.
We know already that a typical household uses about 1000 kWh of energy in one month. Let's investigate the advantages of nuclear energy by considering the following problem: if you were given a gallon of water, how long could it supply fusion energy for your home? In this case, you are considering a fusion reaction between two deuterium nuclei which releases 4.0 MeV. We will follow this problem through to the end in stages. Part I: How many deuterium nuclei...
