Detailed Solution

Energy of photon is given as E=hv

                                                    h=Ev;E=ML2T2;ν=1T

The dimensional formula of plank's constant is ML2T-1

similarly dimensional formula of gravitational constant is M-1L3T-2

Bulk modulus ML-1T-2

coefficient of viscosity ML-1T-1
