A cleansing cream or lotion is used for the removal of facial make - up, surface grime and excess oil. The mineral oil in the cream acts on the grease and excess oil that bind grime or make up on the skin and removes the..

This law is used in comparing the temperature of any two or more systems by the common use of thermometer. For example, in order to compare temperature of two bodies X and Y, the thermometer (analogous to body C) is allowed to come into thermal equilibrium first with body X and then with..

Mechanical properties like strength, stiffness (Rigidity), ductility, malleability and brittleness have to be carefully studied to select a material for a particular job. The metallic parts of machines should not be subjected to stress beyond the elastic limit otherwise they will be deformed. ..

A number which is a factor of two or more numbers is called a common factor of these numbers. e.g., 4 is a common factor of 16 and ..

One of the important applications of Newton's law is to estimate masses of binary stars. A binary star is a system of two stars orbiting round their common center of mass. Any irregularity in the motion of a star indicates that it might be another star or a planet going round t..

A good illustration of the ideas discussed in this chapter is the motion of a cart pulled by a horse. Suppose the cart is at rest when the driver whips the horse. The horse pulls the cart and the cart accelerates forward. The question posed is as follows. The horse pulls the cart with a force..

This heating is inevitable in any electrical circuit. Since the energy lost by the flowing charges ends up as disorderly thermal motion, the phrase 'ohmic dissipation' is also used to describe it. Often, this is an undesirable effect. For example, in electric circuits, the heat produced in a small ..

A hydraulic lift is used to lift heavy loads. It consists of two pistons of varying cross-sectional area. The two pistons are connected to each other with a horizontal pipe. The container is filled with an incompressible liquid. The load to be lifted, is placed on the piston of larger cros..

. If m 1 m 2 = -1 the curves are orthogonal. The condition for the function f(x) to be increasing at x = a if f ' (a) >0. The condition for f(x) to be decreasing at x = a if f ' (a) < 0. A function f(x) is said to be strictly increasing at x = a if f(x) > f(a) whenever x > a in the..
