$\mathrm{VS}$ is unit of which physical quantity ?
The unit of reactance is
If $x = at + b{t^2}$, where $x$ is the distance travelled by the body in kilometres while $t$ is the time in seconds, then the units of $b$ are
If ${u_1}$ and ${u_2}$ are the units selected in two systems of measurement and ${n_1}$ and ${n_2}$ their numerical values, then
$Erg - {m^{ - 1}}$ can be the unit of measure for
The velocity of a particle depends upon the time $t$ according to the equation $v = \sqrt {ab} + bt + \frac{c}{{d + t}}$ The physical quantities which are represented by $a, b, c$ and $d$, are in the following order
