b There are $3$ stgnificant figures in the measured mass whereas there are only $2$ significant figures in the measured volume. Hence the density should be expressed to only $2$ significant figures.
$\text { Density } =\frac{5.74}{1.2} \;g \,cm ^{-3}$
$=4.8\; g \,cm ^{-3}$

To find the distance $d$ over which a signal can be seen clearly in foggy conditions, a railways engineer uses dimensional analysis and assumes that the distance depends on the mass density $\rho$ of the fog, intensity (power/area) $S$ of the light from the signal and its frequency $f$. The engineer find that $d$ is proportional to $S ^{1 / n}$. The value of $n$ is:
If velocity $v$, acceleration $A$ and force $F$ are chosen as fundamental quantities, then the dimensional formula of angular momentum in terms of $v,\,A$ and $F$ would be
If the speed of light $(c)$, acceleration due to gravity $(g)$ and pressure $(p)$ are taken as the fundamental quantities, then the dimension of gravitational constant is
If the acceleration due to gravity is $10\,m{s^{ - 2}}$ and the units of length and time are changed in kilometer and hour respectively, the numerical value of the acceleration is
The distance of the Sun from earth is $1.5 \times 10^{11} \,m$ and its angular diameter is $(2000) \,s$ when observed from the earth. The diameter of the Sun will be ...........
The dimensions of Stefan-Boltzmann's constant $\sigma$ can be written in terms of Planck's constant $h$, Boltzmann's constant $k_B$ and the speed of light $c$ as $\sigma=h^\alpha k_B^\beta c^\gamma$. Here,
