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.
Properties of Lines of Flux To make the imaginary lines of flux describe the behaviour of the magnetic field we must give them appropriate properties. Thus lines of flux have
Find the value of g by free fall method.
consider a star orbitining in the sperically graviational potential Y=(Vc)2 ln(r/r0). a)use conservation of energy and angular momentum to obtain equation for dr/dt and d(teta)/dt
Concept of wave front The basis of Huygens wave theory of light is his principle concerning construction of wave front. When a disturbance from a light source travels i
what is plane diffraction grating?
Le Chatelier's principle (H. Le Chatelier; 1888) If a system is in equilibrium, then any change imposed onto the system tends to shift the equilibrium to decrease the effect of
#quest. Imagine a small observer is positioned in front of the cork in your picture above. As the cork approaches, the observer measures the wavelength of the waves passing by. How
You pull a simple pendulum of length 0.240 m to the side through an angle of 3.50 degrees and release it. a) How much time does it take the pendulum bob to reach its highest speed?
Define isothermal process For isothermal process temperature remains constant i.e. Δu = 0. Thus according to first law of thermodynamics ΔQ =Δw Heat supplied to the syste
