For an electrical component, the formulas for charge and voltage are given below. A is 9 coulombs, B is 12 seconds, C is 3 volts, and D is 24 seconds. Give the power of this component at t = 7 sec. You must round your answer to the nearest thousandth and give your answer as an integer followed by the appropriate metric prefix and the letter that represents the units of power.
Suppose the cost of an incandescent bulb is 28 cents and that electricity costs 10.5 cents/kWh. Compact fluorescent lightbulbs (CFL), while they are more expensive, use 1/10 of the power for the same amount of illumination. What would be the maximum cost (in dollars) of a CFL such that the total cost (investment plus operating) would be the same for both CFL and incandescent 60 W bulbs? Assume both lightbulbs run for 1000 h.

A coil of Nichrome wire is 23.0 m long. The wire has a diameter of 0.400 mm and is at 20.0°C. (a) If it carries a current of 0.600 A, what is the magnitude of the electric field in the wire?(b) If it carries a current of 0.600 A, what is the power delivered to it?(c) If the temperature is increased to 300°C and the potential difference across the wire remains constant, what is the power delivered? A coil of Nichrome wire is 23.0 m long. The wire has a diameter of 0.400 mm and is at 20.0°C. Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.
