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.
Define the term scanning electron microscope. Scanning electron microscope: The scanning electron microscope (SEM) is a form of electron microscope which images the sample s
A scooterist is racing at a speed of 72 km per hour. If the radius of the wheel is 20 cm, find the angular speed of the wheels. Ans) 72kmph=20m/s 20cm=0.2m; v=rw w=v/r w=20/0
Defect of short sightedness In this defect the image of the object is formed in front of retina or the lens become so converging.
Consider a horizontal cylinder with diameter D and length L. The center of the cylinder is a distance a above the ground. A wall with length W and height H is located to the side o
Light propagates as transverse EM rays. The magnitude of electric field is much larger as compared to magnitude of magnetic field. We generally prefer to define light as electric f
Hi i am doing research right now on anti-matter. I am just wondering if it is present in the human body?
Medical uses of cryogenics Low temperature have been used for long term preservation of blood, sperms, bone marrow and tissues. Cryosurgery The cryogenic methods used to
Consider the 4-f system below where an object is placed at the input plane and is illuminated by a plane wave With the object from part a) inserted in the input plane, a m
There are two major differences between "center of gravity" and "center of mass": 1) The term "center of gravity" aplies to the bodies with mass and weight, while the term "cent
