Vedclass · Answer

(C) The velocity of sound is a type of speed or velocity,which is defined as the rate of change of displacement with respect to time.Dimensional formula of velocity = $\frac{[	ext{Displacement}]}{[	ext{Time}]}$.Since displacement has the dimension of length $[L]$ and time has the dimension $[T]$,the dimensional formula is $\frac{[L]}{[T]} = [L{T^{ - 1}}]$.Expressing this in terms of mass,length,and time,we get $[{M^0}L{T^{ - 1}}]$.
