Answer 2

Given : dimensions of area * velocity

To Find :   The dimensions of area * velocity have the same dimensions as

Volume

Energy

Momentum

Volume of liquid flowing per second​

Solution :

Dimension of area = L²

Dimension of Velocity = LT⁻¹

dimensions of area * velocity   =L² *  LT⁻¹

= L³T⁻¹

L³  is dimension of volume

L³T⁻¹  is dimension of volume  per sec

Hence Volume of liquid flowing per second​  is correct answer

The dimensions of area * velocity have the same dimensions as Volume of liquid flowing per second​  =  L³T⁻¹

Dimension of volume  =  L³

Dimension of energy :  = M L² T⁻²

Dimension of momentum = MLT⁻¹
