Maximum EMF E 0 = NBA w = 20 x 3 x 10 - 2 x 3.14 x (8 x 10 - 2 ) 2 x 50 volt = 0.6 volt Average EMF for one cycle is zero. Maximum current, Power loss The source of this power is the external agent (motor) which helps the coil rotating against the torque of the induce..

= 200 Mev = 200 x 1.6 x 10 - 1 3 J = 3.2 x 10 - 1 1 J 1kW = 1000 W = 1000 Js - 1 If x be the number of fissions per second required to generate a power of 1kW, then..

The law of mass action correlates the rate of a chemical reaction and the concentration of the reactants. C.M. Guldberg and P. Waage (1864-67) suggested this relationship. This law states that, at a constant temperature and pressure, the rate of a chemical reaction is directly propo..

The principle of quantisation of electric charge states that "in nature there is a smallest amount of charge and all other charges are integral multiples of this smallest unit ". That is, if e is the minimum charge then the total charge on the body is equal to ne where n is an integer. This fact t..

Upto the year 1924, electron was exclusively regarded as a particle. However, in 1924, de-Broglie suggested that an electron behaves both as a material particle and as a wave. Just like light, some experimental facts can be explained by assuming electrons as tiny particles while some oth..

> How do infrared and g - rays differ in their (i) wavelength and (ii) penetrating power. Suggested Answer:- (i) g - rays have much shorter wavelengths of the order of 10 - 1 3 m while the infrared have longer wavelengths of the order of 10 - 6 or more. (ii) g - rays have a much higher pe..

Steering wheels, spanner, screw drivers and bicycle pedals all use the principle of wheel and axle. Solved Examples: Example 1 : Figure below shows the use of a lever to lift a boulder of weight 3000 N by applying a suitable effort at C. If AB = 1 m and BC = 6 m, calculate the effort required to li..
