The flow of liquid varies with speed of the liquid inside the pipes. Consider a pipe PQ through which a liquid flows. Let be the velocity of particles of liquid as shown in the diagram. If all the particles have the same velocity (meaning, both magnitude and direction), then the flow of liquid is o..

Decomposition - It is a chemical reaction in which molecules of a substance break down to form simpler molecules of two or more new substances. Decomposition of a substance, due to heat is called thermal decomposition, while decomposition due to electricity, is called electrolytic decomposition. Me..

When the impurity atom is a trivalent atom say indium, boron or aluminium, these atoms will replace the silicon atom as shown. The 3 valence electrons of Indium atom bond covalently with 3 of silicon atom. There is one incomplete covalent bond due to deficiency of an electron. This bond can be comp..

Therefore, environment includes nature, composition of air, characters of hydrological parameters, sunshine, air pressure, temperature, water resources - their storage and flow and all other physical paramet..

Angle - When two straight lines meet at a common point, they form an angle. and are called arms of the angle BAC. The point 'A' is called the vertex. The angle formed by the two rays AB and AC is denoted by the symbol BAC. If there is only one angle at A, then the angle BAC may be denoted ..

Nutrition - Nutrition can be defined as the process by which an organism obtains food which is used to provide energy and materials for its life sustaining activities. Thus the term nutrition includes the means by which an organism obtains its food and also the processes by which the nutrients in t..
