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..

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..

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..

. The major problem of corrosion occurs with iron (or steel) as it is used as a structural material in industries like construction, infrastructure, bridges, rail transport power transmission, shipbuilding, automobiles, heavy industries etc. Aluminium, another useful structural metal, als..

>Three types of radiation from recognized radioactive elements are a -particles, b -particles and g -radiation. It was realized that radioactivity of an element is independent of its physical state, its chemical environment or temperature, suggesting that it is a property of the nucleus i..

Stefan-Boltzmann Law - The energy of thermal radiation emitted per unit time by a black body of surface A, is given by u = s AT 2 -----(1) where s is a universal constant known as Stefan-Boltzmann constant and T is its temperature on absolute scale. The measured value of s is 5.67 x 10 - 8 W/m 2 - ..
