Aperson in good physical condition can put out 100 w of useful power for several hours at a stretch, perhaps by pedaling a mechanism that drives an electric generator. neglecting any problems of generator efficiency and practical considerations such as resting time: (a) how many people would it take to run a 4.00-kw electric clothes dryer? (b) how many people would it take to replace a large electric power plant that generates 800 mw?

(a) 40 people

Explanation:

- The power produced by a single person is

- The total power to run the dryer is

- So, the number of people needed would be the ratio between the total power needed and the power generated by a single person:

(b) 8 million people

Explanation:

- The power produced by a single person is

- The total power to replace the electric power plant is

- So, as before, the number of people needed would be the ratio between the total power needed and the power generated by a single person:

which corresponds to 8 million people.
