Question1

A 32 percent efficient electric power plant generates 700MW of electric power and discharges waste heat into 20C ocean water. Assume the waste heat could be used to heat homes during the winter in its place of being discharged into ocean. A typical American house requires an average 20 kW for heating. How many homes could be heated with the waste heat of this one power plant?

Question2

If a person can jump a horizontal distance of 3.44 m on Earth, how far could the person jump on the moon, where free-fall acceleration is g/6 and g = 9.81 m/s2?
How far can a person jump on Mars, where the acceleration because of gravity is 0.38 g? In meters.
