In may you used 400 kilowatt-hours of energy for electricity. a. calculate the total electrical energy use in joules. b. calculate your average power use in watts. c. assume that your power supplier generates electricity by burning oil. note that 1 liter of oil releases 12 million joules of energy. how much oil is needed to generate the electricity you use? give your answer in both liters and gallons. a. the total electrical energy use was nothing _ joules. (type an integer or a decimal.) b. the average power use is nothing _ watts. (round to the nearest whole number as needed.) c. to generate the electricity you used, nothing _ l is needed. (round to the nearest whole number as needed.) to generate the electricity you used, nothing _ gal is needed. (round to two decimal places as needed.)

a)Energy used in may in joules in month of May is 1,440,000,000 Joules.

b) Average power use in watts is month of May is 538 watts.

c)Oil needed to generate the electricity we use in month of May liter is 12 L or 3.17 gal

Step-by-step explanation:

Energy used in may = 400 kilowatt-hour = 400,000 watt-hour

1 hour = 3600 seconds

1 joule = Watt × seconds

a) Energy used in may in joules :

400,000 watt-hour=

Energy used in may in joules in month of May is 1,440,000,000 Joules .

b) Average power use in watts.

Time = 2,678,400 seconds

( May = 31 days,1 day = 24 hours,1 hour = 3600 seconds)

Average power use in watts is month of May is 538 watts.

c) Oil needed to generate the electricity we use

 of energy is generated 1 Liter of oil

Then of energy will be generated by:

of oil

1 Liter = 0.264172 gal

12 liter of oil =

Oil needed to generate the electricity we use in month of May liter is 12 L.

Oil needed to generate the electricity we use in month of May gallons is 3.17 gal
