Atypical person can maintain a steady energy expenditure of 400 w on a bicycle. assuming a typical efficiency for the body and a generator that is 85% efficient, what useful electric power could you produce with a bicycle-powered generator? express your answer to two significant figures and include the appropriate units.

we will get 340 W of output power when there is an input energy of 400 W with 85% efficient generator

Explanation:

As we know that efficiency of the generator is given as 85 %

so we can define efficiency of the generator as

100

so here we know that efficiency is 85 %

so it shows that it will given us 85% of output work when we give it some energy or input

So we will have

So we will get 340 W of output power when there is an input energy of 400 W with 85% efficient generator

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
