A) v
B) \[{{v}^{2}}\]
C) \[{{v}^{3}}\]
D) \[{{v}^{4}}\]
Correct Answer: C
Solution :
[c] Number of particles string the blades/time \[\propto \] velocity of wind K.E. of particle \[\propto \] (Velocity of wind)2 \[\therefore \]Power output \[\propto \] (No. of particles striking/ time) \[\times \] (K.E. of particle) \[\therefore Power output~\propto {{v}^{3}}\]You need to login to perform this action.
