law of sets

Let * be a binary operation on the set S. * is said to be associative in S if " a, b S a * b = b ..

If A, B are two sets, then..

If A, B, C are three sets, then..

Fig: 9.9 - Experimental set up for the verification of the Second Law of Electrolysis According to the second law of electrolysis, the same quantity of electricity will produce or dissolve chemically equivalent amounts of all the substances. Therefore, the same quantit..

Law of Combination of Resistance in Parallel - Connect two resistors 'R 1 ' and 'R 2 ' in parallel to one another between the points A and B. Connect this combination to a battery of potential 'V..

Law of Combination of Resistors in Parallel - Connect two resistors 'R 1 ' and 'R 2 ' in parallel to one another between the points A and B. Connect this combination to a battery of potential 'V'. Here the potential difference across R 1 and R 2 will be equal to battery voltage. But the t..

The Algebraic Properties of set operations are: Idempotent laws, Identity laws, Commutative laws, Associative laws, Distributive laws, De Morgan's Laws..

Let us consider a student seated on a stool that can rotate freely about a vertical axis. The student, who is set into rotation at a modest initial angular speed wi, holds two dumbbells in an outstretched hand. His angular momentum lies along the vertical rotation axis, pointing upw..

Galileo Galilee (1564-1642), a great Italian scientist raised a number of questions about the action of forces on a body with respect to the motion of the body. He performed various experiments and answered those questions by studying the results of his experiments. Aristotle, a Greek philosop..

Physical, chemical and mathematical sciences follow a specific set of rules and regulations. They are governed by a set of laws such as the law of gravity, the laws of thermodynamics, the law of conservation of mass and so on. Howeve..
