Q-3 Hmwk #2
In a sunnier location than Eugene, the sun shines for an average of 2000 hours per year. A home owner installs solar panels that generate 3.5 kW from these panels when the sun is shining. If the local electric utility charges $0.15 per kWh, how much money do the solar panels save the home owner per year? Give the answer to the nearest dollar.

Unfortunately, he forgot to lock his safety tether in place , and he has drifted 5.0 m away from the capsule . Fortunately, he has a 1000 W portable laser with fresh batteries that will operate it for 1.0 h. His only chance is to accelerate him self toward the space capsule by firing the laser in the opposite direction. He has a 10-h supply of oxygen. How long will it take him to reach safety ?arrow_forwardWhy is the following situation impossible? A politician is decrying wasteful uses of energy and decides to focus on energy used to operate plug-in electric clocks in the United States. While many people use their smartphone as an alarm clock, he estimates that there are still 270 million plug-in alarm clocks in continuous use. The clocks transform energy taken in by electrical transmission at the average rate 2.50 W. The politician gives a speech in which he complains that, at today’s electrical rates, the nation is losing $100 million every year to operate these clocks.arrow_forward
- LED bulbs are much more efficient at producing light than are traditional incandescent bulbs. They initially cost much more, but last far longer and use much less electricity An LED bulb that produces as much light as a 100 W incandescent bulb uses only 12.5 W of power. The LED bulb lasts 15,000 hours, on the average, and costs £8.00, whereas the cost of an incandescent bulb was only £0.75, but it lasted just 750 hourS. Assume that electricity costs £0 122 per kilowatt-hour and that the bulbs are on for 4.0 h per day.
