Ampere's law, modified form:
The line integral of the magnetic field about a closed curve is proportional to the total of two terms: first one, the algebraic total of electric currents passing through that closed curve; and second one, the instant time rate of change of the electric flux by a surface limited by that closed curve; in differential form,
curl H = J + dD/dt,
where d/dt revel partial differentiation.
Additionally to defining electromagnetism, his equations also predict which waves can propagate by the electromagnetic field, and always would propagate at the similar speed these are electromagnetic waves; the speed can be determined by calculating (epsilon0 mu0)-1/2, which is c, the speed of light within vacuum.
When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
By what percentage should the pressure of a given mass of gas be increased,so as to decrease its volume by 10% at a constant temperature.
Two moles of an ideal gas expands reversibly and isothermally to ten times its volume at 25°C. Evaluate the change in entropy during the process. ( R = 8.314 JK -1 mol -1 )
calculate the frequency of radiation which must be incident on a substance placed in magnetic field strength so that the electron can absorb energy
