Surface tension can be explained in given possible ways:
(i) The property of a liquid on account of which it tends to keep minimum number of molecules in its free surface is described as surface tension.
(ii) The characteristics of a liquid, on account of which it leads to minimize it's free surface area, is called as surface tension.
(iii) The work, required to be done in increasing the free surface of a liquid by unity at constant temperature, is described as surface tension.
(iv) The force operating per unit length of an imaginary line drawn on the free liquid surface at right angles to the line and in the plane of liquid surface is described as surface tension.
Total magnetic flux density B in a material is the amount of magnetic flux density in vacuum formed by magnetizing force and magnetic flux density because of magnetization of mater

It is the degree or extent by which magnetic lines of force can enter a substance and is expressed by µ.
(1) Holes works as virtual charge, although there is no charge on holes. (2) Effectual volume of hole is more than electron. (3) Mobility of hole is fewer than electron.
UNIFORM ACCELERATION: If velocity of a body alters by equal amounts in equivalent intervals of time, then the body is said to have uniform acceleration. OR If average a
