Measurements
Measurements - Everything that we use in our daily life is ultimately governed by principles of physics. All gadgets we use everyday at home, bicycles and cars, all different types of machinery and instruments, work on principles of physics. Hence to understand even the elementa..
Need for Studying Biology
What is the need for studying Biology? The study of Biology becomes important for the following reasons: It brings about an awareness of the rich diversity of life forms that inhabit the Planet Earth It helps us to know and appreciate the precision and complexity of living processes An under..
Nuclear Fusion Reaction
Nuclear fusion is a reaction in which two or more light nuclei combine to form a heavier nucleus releasing an enormous amount of energy: Nuclear fusion takes place at a very high temperature of the order of 10 7 Kelvin Hence nuclear fusion reaction is called thermo nuclear reaction N uclea..
Reasons for Mendel's Success
Reasons for Mendel's Success - Many scientists earlier to the period of Mendel had attempted breeding experiments in both plants and animals. However, most of them failed to arrive at any specific conclusions or principles to explain the pattern of inheritance. In fact, many of these scie..

Ignorance about many basic facts leads to psychological problems like Misconceptions about sexual feelings, sex related issues. Misconceptions about child birth, reproduction. Misconceptions about coitus, menstrual cycles. Fear about sex and sexual issues. Guilt feeling about sex related ..
Summary
Electric charge is a basic property of all matter. Unlike charges attract, like charges repel. Conductor allow flow of electric charges through them while insulators don't. Electric charges have three basic properties (a) Additivity (b) Quantisation (c) Conservation ..
Brief history
. In 1907, Korn sent the first inter-city fax when he transmitted a photograph from Munich to Berlin. This was perhaps the greatest boost the fax machine had faced so far, and soon many people would try to perfect the machine. In France, Edouard Beeline constructed the Belinograph. His invention in..

The concepts of solubility product and common ion effect play an important role in qualitative analysis for the separation of basic radicals (cations) into different groups. Weak acids and weak bases ionise in water slightly and an equilibrium is established in their solutions. For examp..
