4 physical properties of

1) No point can be at different potentials, so equipotential surface for different potentials can never touch or intersect. 2) Potential energy does not change as a test charge moves over an equipotential surface and hence the electric field can do no work on such a charge. Because of this reason ..

(i) a - rays consists of a -particles carrying double positive charge having a mass roughly four times that of hydrogen atom. (ii) Due to large mass, their penetrating power is very small. (iii) Due to large mass and velocity they have a large ionizing power. (iv) a - rays produce ..

. Hence, a diode acts like a one-way valve in a circuit, and is then called a rectifie..

.98U, which are nearly integral multiples of the mass of hydrogen atom. Their relative abundances are 75.4 and 24.6 percent respectively. Mass of natural chlorine atom can be found as = 35.47. The isotope can occur either naturally or can be produced artificially in the laborator..

Predict the effect on the electrical properties of a silicon crystal at room temperature (300 K) if every millionth silicon atom is replaced by an atom of indium. Given: concentration of atoms = 5 x 10 2 8 m - 3 ; intrinsic carrier concentration = 1.5 x 10 1 6 m - 3 ; intrinsic conductivi..

Even though the laws of friction have been understood since a long time, some properties were understood properly, only after the discovery of atoms and molecules. No matter how well polished two surfaces are, at the atomic level they are never plane. Sometimes, when these extremely well..

Radioactive Decay or Disintegration - A radioactive nucleus or element emits an alpha or a beta particle and gets converted into a new nucleus or element. The process of destruction of the original nucleus during the formation of new nucleus due to radioactivity is called Radioactive decay or disin..

The restoring force in a spring (or in general, any elastic body) obeys Hooke's law. An English scientist Robert Hooke, in the year 1679, enunciated the fundamental law of elasticity in the form ut tensio sic vis which means, As the tension, so is the extension. Within the elastic limits, the defor..

An optical fiber is a dielectric wave guide that transports light signals from one place to another just as a twisted-wire pair or a coaxial cable transports electrical signals. It consists of a central core within which the propagating electromagnetic field is confined and which is surrounded by a..
