- ost Lab Questions: 1. A kilowatt-hour is the unit of energy electric companies use. This is 3,600,000 Joules. You can buy a kilowatt-hour of energy in Colorado right now for around 11.79¢ (the price changes due to the location and time of year). To get a feeling for how much a kilowatt-hour is, consider illuminating ten 100-watt light bulbs (that's 1,000 watts or 1 kilowatt). That's a lot of light. If you kept all of them burning for an hour, that would be a kilowatt-hour. a. How many stairs would you have to run up to create that much energy? b. Would you do that for 11.79¢? 2. Abbie and Bonita decide to race up a hill that is 30 meters high. It takes Abbie 45 seconds since her route is steep while Bonita runs up her path in 30 seconds. They both start from rest at the same height and stop at the top. Abbie has a weight of 700 N while Bonita has a weight of 500 N. Abbie Bonita in going up the hillPls help ASAP. Pls help on all and pls provide clear and easy to follow solutions.In May you used 1500 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? Giv your answer in both liters and gallons. a. The total electrical energy use was joules. (Type an integer or a decimal.)
