- You decide to cook your dinner with a microwave instead of firing up the electric oven. You use 1,120 Watts for 15 minutes per dinner. What will it cost you to cook your dinners for a year if your utility charges you 5.5 cents per kWh?An air conditioner, 6400 watts, is used only 4 months out of a year. On a typical day it is used only 5.0 hours. If the cost of electricity is 12 cents per kwh. How much does it cost to run this air conditioner for the 4 months (assume 30 days per month). 137 words English (United States) O Focus MacBook ProOne 9-volt battery contains 19.7 thousand joules of energy. A 4-pack of 9-volt batteries cost $10.31 at Lowe's. Estimate the cost of battery energy in dollars per kilowatt-hour. Energy conversions are available in Section 2.2 of the textbook. Round your final answer to the nearest $10 per kilowatt-hour.
- Assuming that the diet of an average Canadian consumes 2,500 food calories per day (1 cal=4200 J), compare the amount of energy consumed by a Canadian family of 5 in one year in their diet with the amount of electrical energy their household consumes.
