Why material in solid state are crystalline
Most of the materials in solid state are crystalline. Between these many are in the polycrystalline state. To get single crystal one has to employ a suitable crystal growth process. This may differ from one material to another. To understand the dissimilar material properties, the structure of the material is very important. The unit cell which is the building block of a crystalline material can be made of the basic units namely the basis or the pattern unit or the motif.
Write two characteristic features of nuclear force which differentiate it from the Coulomb force.
Constancy principle (A. Einstein): One of the postulates of A. Einstein's special theory of relativity, that puts forth that the speed of light in vacuum is calculated as the
Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential in the hollow conducting shell is found to be:
