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
distance, distance, acceleration, time
distance, acceleration, distance, time
acceleration, distance, distance, time
none of above
Newton-second is the unit of
The unit of potential energy is
In which of the following systems of unit, $Weber$ is the unit of magnetic flux
The velocity of a particle depends upon as $v = a + bt + c{t^2}$; if the velocity is in $m/\sec $, the unit of $a$ will be
The units of modulus of rigidity are
