dimensions of A and B when given the formula speed is equals to A multiplied by acceleration due to gravity squared times density to the power negative one plus B squared multiplied by t
v=Ag2ρ−1+B2t,v=Ag^2\rho^{-1}+B^2t,v=Ag2ρ−1+B2t,
[A]=vρg−2=1 ms⋅kgm3⋅s4m2=1 kg⋅s3m4.[A]={v\rho }{g^{-2}}=1~\frac ms\cdot \frac{kg}{m^3}\cdot \frac{s^4}{m^2}=1~\frac{kg\cdot s^3}{m^4}.[A]=vρg−2=1 sm⋅m3kg⋅m2s4=1 m4kg⋅s3.
[B]=vt−1=1 ms.[B]=\sqrt{vt^{-1}}=1~\frac{\sqrt m}s.[B]=vt−1=1 sm.
