Find the dimensions of

Question:

Find the dimensions of

a) linear momentum

b) frequency

c) pressure

Solution:

 a) Linear momentum = mv

Dimension $=\left[\mathrm{MLT}^{-1}\right]$

b) Frequency $=1 / T$

Dimension $=\left[\mathrm{T}^{-1}\right]$

c) Pressure = Force/Area

Dimension $=\left[\mathrm{MLT}^{-2}\right] /\left[\mathrm{L}^{2}\right]=\left[\mathrm{ML}^{-1} \mathrm{~T}^{-1}\right]$
