The contribution of ionic polarization takes account of the fact that when in a molecule some of the atoms have an excess positive or negative charge (resulting from the ionic character of the bonds),an electric field tend to shift positive ions relative to negative ones. This leads to an induced moment of other origin from the moment induced by electron clouds shifting relative to nuclei. In this case a solid material should have some ionic character. It then automatically has internal dipoles, exactly cancels each other and is unable to rotate. The external field them induces net dipoles by slightly displacing the ions from their rest position. The paradigmatic materials are simple ionic crystal like NaCl. The polarization of a given volume, though, is exactly zero as for every dipole moment there is a neighbouring one with exactly the same magnitude, but with opposite sign. Note that the dipoles cannot dipoles, their direction is permanent. In electric field, the ions feel forces in opposite directions. The Na+ ions moved a bit to the right, the Chlorine ions to the lift. The dipoles moments between adjacent NaCl pairs in field direction are now different and there is a net dipole moment in a finite volume now. It can be observed that it is enough to take one dipole in field direction.
In single sided PCB the conductor tracks run only on one side of copper clad board. Thus crossing of conductors is not permitted. Base material is chosen as per the application. It

Gamma Rays: The wave length of gamma rays is less than 10-11 m.
#question.A tortoise can run with a speed of 0.12 m/s, and a hare can run 20 times as fast. In a race, they both start at the same time, but the hare stops to rest for 4.0 minutes.
Solar Cells: The solar cells that we see on calculators and satellites are photovoltaic cells or modules (modules are easily a group of cells electrically connected and packaged
The waves which do not needs medium for their propagation are known as non- mechanical or electromagnetic waves. Examples : Light, heat (Infrared), radio waves, gamma- rays, X-r
Regard as two charged particles. At a given separation each one particle exerts a force of 12 N on the other. What force does every one exert on the other after someone moves the p
Elasticity is defined as the ability of a solid to return to its original shape even after being expanded or contracted. Elasticity is termed as the property of a solid to return t
