In the formula : y = a sin ( at - b), where y - position, t - time and A, a, b are constants. What will be the dimensional formula of $\frac{b}{a}$?

নিচের কোনটি দুরত্বের একক নয়?  

$\left ( P + \frac{a}{V^{2}} \right ) \left ( V - b \right ) = R T$   সমীকরণটিতে a এর মাত্রা কত?

The dimensional formula for impulse is same as the dimensional

formula for

A force is given by $F = at + b{t^2}$, where $t$ is time, the dimensions of $a$ and $b$ are respectively :
