17.

If A is the projected area of a vehicle in square metres, V is speed of the vehicles in kilometres per hour and C is a constant, then the wind resistance R to the moving vehicles, is given by

 [A]. R = CAV [B]. R = CAV2 [C]. R = CAV3 [D]. [E]. R = C2AV

 Shravan Dixit said: (Jul 11, 2016) @Samm. A is the transverse cross-sectional area of vehicle and v is the velocity of the vehicle. So wind resistance is directly proportional to A and square of velocity constant C is introduced to have a relationship between R, A and V.

 Hossam said: (Apr 28, 2017) How can we calculate C?

 Rajeshnithin said: (Feb 22, 2018) C is the constant. In case does not mention to take 1 value.
