The graph shows the electrical energy consumption of a typical household.... How do you work this?

Question

Question

Answer 1

Answer #1

power = dE/dt

it is the slope of the curve

slope maximum at 7:20PM then at 7:30 AM then at 10:30AM and least at 3:30AM

Answer 2

Answer #2

here , the Power is maximum when the slope of graph is maximum and

lowest when slope is lowest , hence ,

the sequence from least to highest is

3:30 am < 10:30 am < 7:30 am < 7:20 pm

A recent home energy bill indicates that a household used 345 kWh (kilowatt-hour) of electrical energy and 165 therms for gas heating and cooking in a period of 1 month. Given that 1.00 therm is equal to 29.3 kWh, how many milligrams of mass would need to be converted directly to energy each month to meet the energy needs for the home?

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...
