Determine :force experienced by a current carrying straight conductor which is perpendicular to it? |
|
Answer» Fleming’s Left Hand rule gives direction of the current, magnetic field and the force experienced by the wire. The thumb, the first and the second fingers on the left hand are held so that they are at right angles to each other. If the index finger of the left hand points to the direction of the magnetic field, middle finger points the direction of the current flowing through the conductor. Then the direction of the thumb gives the direction of force experienced by the conductor.\xa0\xa0 Fleming’s Left Hand rule gives direction of the current, magnetic field and the force experienced by the wire.

How a glass prism dispersed white light into different colour? |
| Answer» White light is a mixture of lights of seven colors: red, orange, yellow, green, blue, indigo and violet. The dispersion of light occurs because the angle of refraction (or the angle of bending) of lights of different colors is different when passing through the transparent medium (glass prism).So, when white light consisting of seven colors falls on a transparent medium (glass prism) , each color in it is refracted ( or deviated ) by a different angle , with the result that seven colors are spread out to form a spectrum, The red color is deviated least , so it forms the upper part of the spectrum . On the other hand, Violet color is deviated the maximum, so violet appears at the bottom of the spectrum. | |

Define periodic table |
| Answer» The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configurations, and recurring chemical properties. This ordering shows periodic trends, such as elements with similar behaviour in the same column. It also shows four rectangular blocks with some approximately similar chemical properties. In general, within one row (period) the elements are metals on the left, and non-metals on the right.The rows of the table are called periods; the columns are called groups. Six groups have generally accepted names as well as numbers: for example, group 17 elements are the halogens; and group 18, the noble gases. The periodic table can be used to derive relationships between the properties of the elements, and predict the properties of new elements yet to be discovered or synthesized. The periodic table provides a useful framework for analyzing chemical behaviour, and is widely used in chemistry and other sciences. | |

Differentiate between food chain and food web |
| Answer» Food ChainThe series of organisms of an ecosystem through which the food and energy present in it and passes with each member is called food chain. A food chain consists of producers (green plants), consumers (animals and man) and decomposers (micro organisms). Basically there are two types of food chains: grazing food chain and detritus food chain.Food WebIn an ecosystem single food chains never occur. The same organisms may operate at more than one tropic level. So different food chains are inter connected. Thus, in an ecosystem several food chains are linked together and intersect each other to form a complex network called food web.Definition: A number of food chains form a interlinking pattern forming a web like arrangement known as food web. | |
