# Find the  dimensions of (a) linear momentum,(b) frequency and (c) pressure.

##### SOLUTION

(a) Linear momentum:

$=\,mass\,\times \,velocity=[{{M}^{1}}{{L}^{0}}{{T}^{0}}][{{M}^{0}}L{{T}^{-1}}]$

$=\,[ML{{T}^{-1}}]$

(b) Frequency $=\dfrac{1}{time}=[{{M}^{0}}{{L}^{0}}{{T}^{-1}}]$

(c) Pressure

$=\dfrac{Force}{Area}=\dfrac{mass\times acceleration}{Area}=\dfrac{[{{M}^{1}}{{L}^{0}}{{T}^{0}}][{{M}^{0}}L{{T}^{-2}}]}{[{{M}^{0}}{{L}^{2}}{{T}^{0}}]}$

$=[{{M}^{1}}{{L}^{-1}}{{T}^{-2}}]$
