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.
show that in a glass prism that the refractive index n = sin1/2(A+Dmin)/sin1/2A where a = refracting angle. hence if the angle of incidence i on oan air boundary is 60degrees. calc

Using cross belts cross the belt on the spool pulleys used in C 1 above and turn one of the pulleys. Note that they now turn in opposite directions.
Q. A twelve-slit strobe disc is rotated at the max stopping frequency for a vibrating object. The strobe is rotated at 4.0 Hz. (a) Evaluate the period of the vibrating object?
It is the property of the substance which defines how easily a substance can be magnetized. It may also be defined as the ratio of intensity of magnetization (I) in a substance to
Suppose a fluid (say, water) occupies a domain D ⊂ R 3 and has velocity field V=V(x, t). A substance (say, a day) is suspended into the fluid and will be transported by the fluid
Force: Force may be defined as a push or a pull upon an object. In the English system the pound (1b) is used to express the value of a force. For example, we say that a force
