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?

40 persons

Step-by-step explanation:

Data provided :

The power put out by a single person = 100 W

Power required by an electric clothes dryer = 4.00 kW = 4000 W

Thus,

The number of persons required to produce 4000 W of power

= ( Power required ) / ( power produced per person )

or

= (4000 W) / (100 W/ person)

or

= 40 persons

Hence, the number of persons required is 40
