Write the dimensional formula of gravitational constant and latent heat.
Check the correctness of the relation, \(h=\frac{2T\cos\left(\theta\right)}{r\rho g}\), where symbols have usual meaning.
Check the correctness of the formula, PV = RT using the dimensional method.
A student writes an expression of the momentum (p) of a body of mass (m) with total Energy (E) and considers the duration of the time (t) as \(p=\sqrt{2m\frac Et}\). Check its correctness by using dimensional analysis.
Is a dimensionally correct equation necessarily be a correct physical relation? What about dimensionally wrong equation?
The energy of a photon is given by E = hf. Find the dimension and unit of the plank's constant, where f is the frequency of radiation.
