Dimensional formula of velocity of sound is
${M^0}L{T^{ - 2}}$
$L{T^0}$
${M^0}L{T^{ - 1}}$
${M^0}{L^{ - 1}}{T^{ - 1}}$
The pair(s) of physical quantities that have the same dimensions, is (are)
The dimensional formula for impulse is
The dimensions of ${e^2}/4\pi {\varepsilon _0}hc$, where $e,\,{\varepsilon _0},\,h$ and $c$ are electronic charge, electric permittivity, Planck’s constant and velocity of light in vacuum respectively
If velocity$(V)$, force$(F)$ and time$(T)$ are chosen as fundamental quantities then dimensions of energy are
