Find amplitude of electric field ina parallel beam of light of intensity 2W/m2Ans:Given that intensity I=power/area=2W/M2by using this formula :intensity I=(Emax^2/2c mue not)from that Emax=magnitude of electric fieldc=velocity of light=3*10^8m/secmue not =4pi*10^-7Emax=38.82 N/m
Earth and Moon two are act as a two magnets. and when they rotating the flux changes . then the current produces or not . if not what is the reason? Ans) E.M.F is induced only whe
A point charge q is imbedded at the center of a sphere of linear dielectric material (with susceptibility and radiusR). Find the electric field, the polarization, and the bound cha
why can one ignore quantization of charge when dealing with macroscopic charges
They are exactly analogous to water pressure and water flow by a hose. That's why flowing electrons is known as a current, just like a water current. Voltage is the electromotiv
Q. Define critical temperature. The temperature at that electrical resistivity of the material suddenly drops to zero and the material changes from normal conductor to a super
The microwave (rotational) spectrum of 12 C 16 O having a series of lines spaced by 115.3 GHz. Suppose that the rotational energy levels of this molecule can be approximated by
The current in a coil changes of 5A to 10A in 10 -2 s. Then an emf of 50 mill volts is induced in a coil neat it. Determine the mutual inductance of the coil.
I need 4 numerical question about mobility
