Problem 2 If the cost of electricity in your area is 12 cents per kWh, what is the total cost (capital plus operation) of using a 60-W incandescent bulb for 1000 hours (the lifetime of that bulb) if the bulb cost 25 cents? If we replace this bulb with a compact fluorescent light that provides the same light output, but at one- quarter the wattage, and which costs $1.50 but lasts 10 times longer (10,000 hours), what will that total...

Home circuit breakers typically have current capacities of around 9.0 A. How large a magnetic field would such a current produce 4 0 cm from a long wire? Express your answer using two significant figures. How does this field compare with the strength of the earth's magnetic field? This field is the same order of magnitude as the earth's field. This field is far larger than the earth's field. This field is far less than the earth's field.
