A physical quantity $P$ is given by the relation, $P={P}_{0}{e}^{(-\alpha {t}^{2})}$. If $t$ denotes the time, P and P_naught denotes pressure, the dimensions of constant $\alpha$ are

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 :
