Chapter 1, Problem 43P

The average American uses electrical energy at the rate of about 1.5 kilowatts (kW). Solar energy reaches Earth’s surface at an average rate of about 300 watts on every square meter (a value that accounts for night and clouds). What fraction of the United States’ land area would have to be covered with 20% efficient solar cells to provide all of our electrical energy?

you select a rental package that includes a car with an average consumption of 6.00 liters of fuel per 100 km. Considering that in Europe the average fuel cost is 1.063 euros/liter, how much (in US dollars) will you spend in fuel on your trip?
for any wave, the speed equals the wavelength times the frequency. If a photon of visible light has a wavelength of 500 nm (5 x 10-7 m) and a frequency of 6.0 x 1014 Hz, what is the speed of light (in meters per second, scientific notation)?
If the fuel efficiency of an automobile is 27 miles per gallon, what is its fuel efficiency in kilometers per liter? (1 km = 0.621 mile, 1.000 L = 1.057 quarts, 4 quarts = 1 gallon)
