A wind - powered generator convets and energy into electrical energy . Assume that the generator convents a fixed fraction of the wind energy intercepited by to blades into electrical energy for wind speed `V` , the electrical power output will be propertional to

Options

A. `upsilon`
B. `upsilon^(2)`
C. `upsilon^(3)`
D. `upsilon^(4)`

Answer

C

Explanation

`F = (dp)/(dt)=(d)/(dt)(mv)=v(Apv)=Apv^(2)`
`:. P = Fv =(Apv)^(2)v=APv^(3) rArr P alpha v^(3)`.
