hello how to do this
The velocity of water waves v may depend on their wavelength λ, the density of water ρ and the acceleration due to gravity g. Which of the following is a possible relation between these quantities?
A. v2 = kλgρ where k is a dimensionless constant.
B. v2 = k λ-1 g-1 ρ-1 where k is a dimensionless constant.
C. v2 = kλg where k is a dimensionless constant.
D. v2 = kλρ where k is a dimensionless constant.
pls help me..
