Velocity of Sound in Different Gases - As seen from equation (1-28), the velocity of sound in a gas depends on g , the ratio of the principle specific heats of the gas. This, in turn, depends on the atomicity of the gas. An approximate equation connecting g and the degrees of freedom is W..

As seen from equation (1-28), the velocity of sound in a gas depends on g , the ratio of the principle specific heats of the gas. This, in turn, depends on the atomicity of the gas. An approximate equation connecting g and the degrees of freedom is Where n is the number of degrees of freedom. For a..

If A and B are two sets, we define their symmetric difference as the set of all elements that belong to A or to B, but not both A and B, and we denote it by A D B. Thu..

121x 2 - 25y 2 = (11x) 2 - (5y) 2 = (11x + 5y) (11x - 5y) [Using the identity a 2 -b 2 =(a-b)(a+b)] Factorise: (5a + 6b) 2 - 49b 2 Let x = 5a + 6b Then the given expression = (x) 2 - (7b) 2 = (x + 7b) (x - 7b) Re-substitutin..

The principle of homogeneity of dimensional equation is used to derive a relation between various physical quantities. To derive a physical relation, the dependent factors of a given physical quantity is found. Assuming its dimensions in terms of these factors, the final dimensional equation is wri..

Suppose X = a - b Let D a and D b be absolute errors in measurements of quantities a and b, values of a and b and D X be maximum error in X. Maximum absolute error in X = Maximum absolute error in a + Maximum absolute error in b From equations (1) and (2) it is evident that, when result inv..

There are different forms of energy like for example, mechanical energy, heat energy, electrical energy and chemical energy. In this chapter, we shall study about mechanical energy. Kinetic energy and potential energy are the two types of mechanical energ..
