Question

Pedal Power A person in good physical condition can put out 95 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: How many people would it take to run a 4.64–kW electric clothes dryer?

Answer 1

Answer:

48 people would it take to run a 4.64 kW electric clothes dryer.

Explanation:

Given:

Pedal power A $W_{1} = 95$ W

Electric clothes dryer power $W_{2} = 4640$ W

For finding the number of person $n$ equals :

   $n = \frac{W_{2} }{W_{1} }$

   $n = \frac{4640}{95}$

   $n = 48.84$

Therefore, 48 people would it take to run a 4.64 kW electric clothes dryer.
