Binary Operations - Binary Operations are as given below, Commutative Law Associative Law Let S be any non-empty set. An operation * is called a binary operation on S if " a, b Î S a * b Î SLet S be any non-empty..

binary operation: Let S be any non-empty set. An operation * is called a binary operation on S if " a, b S a * b S Commutative law: Let * be a binary operation on the set S. * is said to be associative in ..

Let us refer to a circuit consisting of two switches p and q connected in series with a lamp and battery as shown in figure. The lamp will glow, only if switch p and switch q are closed. If we replace the word 'closed' by T and 'open' by F, the switch will glow only if p = T ..

A is called the composite function of f and g. (ii) If f and g be functions from A to A then fog and gof are both defined. In general fog gof. A function from A x A into A is called a binary operation on A..

can be Pollution due to use of aerosols due to high density of population due to waste disposal system Out of them, major contribution of air pollutants is from industrial pollution and transport related pollution - because industrial activity and transport are continuously ..

Summary - Cell is the structural and functional unit of the organism. Water is the principal constituent of plants and is essential for the maintenance of life, growth and development. Plants absorb water from the soil through their roots, transport it to other parts of the plant through the xylem ..

Relation Between Atomic Number and Atomic Mass - While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well. ..

While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well. If you recall from earlier lessons, Atomic number (Z) is th..

If the aperture of the mirror is small, B lies close to P, \ BF = PF or FC = FP = PF or PC = PF + FC = PF + PF or R = 2 PF = 2f Similar relation holds for convex mirror also. In deriving this relation, we have assumed that the aperture of the mirror is smal..
