If the dimensions of a physical quantity are given by ${\text{M}}^{\text{a}}{\text{L}}^{\text{b}}{\text{T}}^{\text{c}}$, then the physical quantity will

            be

i) Dimensions of velocity$=\left[{\text{M}}^{\text{0}}{\text{L}}^{\text{1}}{\text{T}}^{-1}\right]$

Here$a=0,b=1,c=-1$

ii) Dimensions of acceleration $=\left[{\text{M}}^{\text{0}}{\text{L}}^{\text{1}}{\text{T}}^{-2}\right]$

Here $a=0,b=1,c=-2$

iii) Dimensions of force $=\left[{\text{M}}^{\text{1}}{\text{L}}^{\text{1}}{\text{T}}^{-2}\right]$

$Here a=1,b=1,c=-2$

iv) Dimensions of pressure $=\left[{\text{M}}^{\text{1}}{\text{L}}^{-1}{\text{T}}^{-2}\right]$

Here $a=1,b=-1,c=-2$

The physical quantity is pressure.
