(a) Linear momentum = mv Here, [m] = [M ] and [v] = [LT−1 ]∴ Dimension of linear momentum, [mv] = [MLT−1 ](b) Frequency = 1/ ( Time ) ∴ Dimension of frequency = [T1​]=[M0L0T−1](c) pressure = Dimension of force =[MLT−2 ] Dimension of area = [ L2 ] ∴ Dimension of pressure =[ MLT−2 ]/ [L ] = [ ML−1T−2 ]
