The average annual solar flux in New York is 250 W/m2. Suppose 10 m2 of solar electric panels operating at 10% efficiency were installed on a home there. A) How many kWh of electricity could be collected by these panels in one year?

B) What fraction of the annual electrical requirement of 10,000 kWh for the average home does this represent?

C) How many square meters of solar panels would be required to supply 10,000 kWh per year?

Solar cell a produces 100 joules of energy, when a light source is shown on it for 3 minutes. solar cell b produces 200 joules of energy when the same light source is shown on it for 5 minutes. which solar cell works better? a) solar cell b, because it produces more energy. b) solar cell b, because it generates more power. c) solar cell a, because it produces energy quicker. d) solar cell a, because it generates a greater wattage. eliminate

How can you increase the strength of an electromagnet?

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
