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.
A boat can travel at a speed of 3 m s -1 on still water. A boatman needs to cross a river whilst covering the shortest possible distance. In what direction should he row with resp

Passing Lane A passing lane or overtaking lane is the lane on a multi-lane highway or motorway closest to the center of the road or the central reservation.
Find the lowest frequency for which destructive interference Two loudspeakers, A and B, are driven by the same amplifier and emit sinusoidal waves in phase. Speaker B is 2.00 m
Suppose the sides of a closed polygam represent vector arrangend head to tail rule , what is sum of these vectors ?
Q. How do you compute tensile strength? Answer:- Tensile strength is not actually calculated it's measured. It is classified as the point at which a sample of material fai
Phase in sinusoidal functions or in waves has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called
