Two quantities $A$ and $B$ have different dimensions. Which mathematical operation given below is physically meaningful
$A/B$
$A + B$
$A - B$
None
If mass is written as $\mathrm{m}=\mathrm{kc}^{\mathrm{p}} \mathrm{G}^{-1 / 2} \mathrm{~h}^{1 / 2}$ then the value of $P$ will be : (Constants have their usual meaning with $\mathrm{k}$ a dimensionless constant)
If $C$ and $L$ denote capacitance and inductance respectively, then the dimensions of $LC$ are
A massive black hole of mass $m$ and radius $R$ is spinning with angular velocity $\omega$. The power $P$ radiated by it as gravitational waves is given by $P=G c^{-5} m^{x} R^{y} \omega^{z}$, where $c$ and $G$ are speed of light in free space and the universal gravitational constant, respectively. Then,
The physical quantity $'$Energy Density$'$ has same dimensional formula as
The dimensions of angular momentum , latent heat and capacitance are, respectively.
