Force and impulse

Vedclass · Answer

$	ext { For (A): }	ext { Energy }= kg \cdot m ^2 \cdot s ^2=\left[ ML ^2 T ^{-2}ight]$
$	ext { Torque }= kg \cdot m ^2 \cdot s ^2=\left[ ML ^2 T ^{-2}ight]$
$	ext { For (B) : }	ext { Force }= kg 	imes m / s ^2=\left[ MLT ^{-2}ight]$
$	ext { Impulse }= kgm / s =\left[ MLT ^{-1}ight]$
$	ext { For (C) : }	ext { Angular momentum }= kgm ^2 / s =\left[ ML ^2 T ^{-1}ight]$
$	ext { Planck's constant }= kgm ^2 / s =\left[ ML ^2 T ^{-1}ight]$
$	ext { For (D) : }	ext { Elastic modulus }= kg / m ^2=\left[ ML ^{-2}ight]$
$	ext { Pressure }= kg / m ^2=\left[ ML ^{-2}ight]$
From the above data, only Force and Impulse does not have equal dimensions.
