The time required for an outlet pipe to an empty a tank is inversely proportional to the cross-sectional area of the pipe. a pipe with the cross-sectional area of 113.0 square inches requires 6.4 hours to empty a certain tank if the pipe was replaced with one with a cross-sectional area of 50.25 square inches, how long would it take to empty the same tank

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.)
