Tanya was reading a novel, which had 10 chapters. She spent 1 hour(s) reading the first chapter and took the same amount of time to read all the other chapters of the novel. She completed reading the novel in 19 hours. Solve the equation 1 + 9 h = 19, to find h , the n..
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 Where n is the number of degrees of freedom. For a..

Consider two points in an electric field. If a free test charge +q o was placed in the field, it would flow from b to a. So we say b is at higher potential. The electric field does negative work in moving the test charge q o from a to b. If a and b are two points in an electric f..

Consider a carrier wave represented by Here e c is instantaneous value, E c is amplitude (maximum value), w c is angular frequency and q is the phase angle of carrier voltage. Corresponding to the three variables E c , w c and q, we can have three different types of modulatio..

An electron is accelerated from rest through a potential difference of 3 KV. It enters into the region of a uniform, perpendicular magnetic field of 0.2T. What is the radius of the path of electron inside the fiel..
Potential Difference
(higher potential to lower potential). Note that the free electrons flow in the direction opposite to the conventional current. For electrons to be driven through a resistance, there has to be a potential difference across its ends. Work is done by the electrical force due to this potenti..

The length of a cabin is 13 m and the length of a table in the cabin is 6.87 m. Find the difference between their lengths. => 7.13 m or 5.13 m or 7.33 m or 6.13 m..
Different Forms of Energy
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..
