In this case, q = 0 0 b = 0 0 i.e., the resultant vector also points in the direction of the given vector. In this case, ..

Example, Collision between two billiard balls. Case (ii) When v 2 i = 0 i.e., when the body B is initially at rest. From equation (iv), From equation (v), Now, three special sub-cases arise. Sub-case (a) When m 2 << m 1 i.e., when the mass of body B is negligible as compared to the ..

(1) It is used for medical diagnosis and therapy and also as a surgical tool. (2) Bats and porpoises use ultrasound for navigation and to locate food in darkness. (3) It is used to detect defective foetus. (4) It is used as a tool in the treatment of muscular pain. (5) Sonogram (is a tech..

It is special type of hydrometer used for testing the purity of milk or to check richness of milk. It has a range of relative density 1.105 to 1.0..

Liquid and gaseous fuels form explosive mixtures making them difficult to handle. Since they require special leak proof containers their storage is difficult. They are expensive compared to solid fuel..

The meter scale enables us to measure the length to the nearest millimeter only. Engineers and scientists need to measure much smaller distances accurately. For this a special type of scale called Vernier scale is use..

is waveform perturbation caused by imperfect response of the systems to the desired signal itself. Unlike noise and interference, distortion disappears when the signal is turned off. If the channel has a linear but distorting response, then distortion may be corrected, or at least reduces, with th..

Radio isotopes are used in detection of diseases and also in radio therapy: The rays from radium is used in the treatment of skin diseases. Radiation from Co 6 0 ( - rays) is used to diagnose and treat thyroid disorders. Radio iodine (I 1 3 1 ) is used to diagnose and treat ..

A device in which wind is used to rotate the blades of a fan like structure is called a windmill. The windmill works on a very simple principle. When the blowing wind strikes across the blades of a windmill it exerts a force which rotates its blades. The rotational effect is due to a special..

Principle of electrostatics and electromagnetism play a very vital role in all modern scientific developments. Coulomb's law may be regarded as merely a special case of Gauss' law or we can say Gauss's law is generated form of Coulomb's law. Gauss' law makes it possible to calculate in a ..
