= 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..

Due to depletion of underground water, the tube wells dry up, thereby causing severe water shortage. Environmentalists have suggested the following measures for avoiding misuse and wastage of potable water: Development of integrated watershed for drinking, irrigation and industrial use Ad..

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..

Chemical disinfection is brought about with the use of chemical disinfectants such as bleaching powder, chlorine solution, ethanol solution of iodine and potassium permanganate. Chlorine tablets are available at cheap rates to disinfect water. A single tablet of 0.5g is sufficient to disinfect 20 l..

. In 1858, a German biologist Rudolph Virchow found that all living cells arise from pre-existing cells ('omniscellula e cellula'). In 1866 Ernst Haeckel suggested that nucleus might store and transmit the hereditary information. The improvement made in the field of microscopes and t..

Applications of Lasers - The development of the laser has opened many avenues of investigation and improved many others. The important characteristics that have contributed to its usefulness in these many areas are tile coherence, monochromaticity and great intensity of its radiation. (i) The small..

> 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..
