The dimensional formula ${M^0}{L^2}{T^{ - 2}}$ stands for

The dimension of $\frac{E^2}{\mu_0}$ in mass $(M)$, length $(L)$ and time $(T)$ is ($E=$ electric field, $\mu_0=$ permeability of free space).

Time $(T)$,velocity $(C)$,and angular momentum $(h)$ are chosen as fundamental quantities instead of mass,length,and time. In terms of these,the dimensions of mass would be

Write the dimensional formula of power. Is power a vector or scalar quantity?

What is the dimensional formula of an electron volt $(eV)$, and what is its value in Joules $(J)$?

The dimension of electric current is
