Compact fluorescent bulbs aremuch more efficient at producing light than are ordinary incandescentbulbs. They initially cost much more, but they last far longer and usemuch less electricity. According to one study of these bulbs, a compactbulb that produces as much light as a 100 W incandescent bulb usesonly 23 W of power. The compact bulb lasts 10,000 hours, on the average,and costs $11.00, whereas the incandescent bulb costs only $0.75,but lasts just 750 hours. The study assumed that electricity costs $0.080per kilowatt-hour and that the bulbs are on for 4.0 h per day. What is the resistance of a “100 W” fluorescent bulb? (Remember, it actually uses only 23 W of power and operates across 120 V.)
One 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.
