If the speed $v$ of transverse waves on a stretched string depends on the tension $T$ in the string and the mass per unit length $μ$ of the string, which of the following is dimensionally consistent?

If 1 g cm ${{\rm{s}}^{ - 1}} = x$ newton-second, then the number x is equal to

In the equation $F = ma$, if the unit of force ($F$) is newton (N), mass ($m$) is kilogram (kg), and acceleration ($a$) is $ms^{-2}$, is the equation dimensionally homogeneous?

A pressure of ${10^6}$ dyne ${\rm{c}}{{\rm{m}}^{ - 2}}$ is equivalent to
