The power for a hoverting helocipter depends on its linear size, the density of air and (gxx"density of the helicopeter)as Power"oo("linear size")^(x)("density of air")^(y)(gxx"density of helicopter")^(z) where g is acceleration due to gravity. Given ,[Power] =ML^(2)T^(-3),[Linear size]=L'[Density]=ML^(-3) The ratio of power output of engines of two helicopters is one fourth of linear size of other and all other parameters remaining same is
