Here column-I represents the some prefixes and column-II represents the power of ten corresponding prefixes.
Deca $=10^1$ , hecto = $10^2$ , kilo = $10^3$ , mega $=10^6$ , giga $=10^9$
Thus, A-r, B-s, C-p, D-q, E-u

The frequency of vibration of the string is given by

$v=\dfrac {p}{2l}\left [ \dfrac {F}{m} \right ]^{1/2}$

Here, p is the number of segments in the string and l is the length. The dimensional formula for m will be

নিচের কোনটি দুরত্বের একক নয়?

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

The Van der Waal's equation of state for some gases can be expressed as:

$(P + \dfrac{a}{V^2})(V - b) = RT$

where P is the pressure, V is the molar volume, and T is the absolute temperature of the given sample of gas and a,b and R are constants.

The dimensions of a are
