The amount of solar energy received on the Earth's surface per unit area per unit time is defined as the solar constant. The dimension of the solar constant is:

The fundamental physical quantities that have the same dimensions in the dimensional formulae of torque and angular momentum are

The electrical resistance $R$ of a conductor of length $l$ and area of cross-section $a$ is given by $R = \frac{\rho l}{a}$,where $\rho$ is the electrical resistivity. What is the dimensional formula for electrical conductivity $\sigma$,which is the reciprocal of resistivity?

Dimensions of $\frac{1}{{\mu _0 \varepsilon _0}}$,where symbols have their usual meaning,are:

The dimension of the ratio of angular momentum to linear momentum is
