The figure below conceptualizes the parameters that are relevant for waves created by wind blowing across the ocean. To determine the wave height, H, several variables should be considered including the wind speed, V, the water density, ρ, the air density, ρ_a, the water depth, d, the distance from the shore, l, and the gravity acceleration, g, . 

Using d, V, and ρ as repeating variables, complete below the dimensional analysis to determine a suitable set of Π terms that could be used to describe this problem. 

Two dimensionless parameters that relate H and ρ_a with repeating variables have already been determined as Π₁=H¹d^-1V⁰ρ⁰ = H/d and Π₂=ρ_a¹d⁰V⁰ρ^-1 = ρ_a/ρ respectively. In order to complete the analysis, you are tasked to identify other dimensionless Π groups
