Structure of Atom
When scientists started exploring matter, they discovered that the smallest particle of an element that maintains its chemical identity through all chemical and physical changes is called and 'atom'. Just how small these atoms are can be made out if you realize that there are about 60,000,000,000,..

Villi are finger-like projections in the small intestine. Each villus is made up of connective tissue and smooth muscles. The villi are lined by a single layer of thin walled epithelial cells through which the absorption takes place. The fats are absorbed into the lymphatic system. In the centre o..

Light Intensity - Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However, after reaching an intensity of 10,000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may, in fact, slow d..

Law of conservation of energy states that the energy can neither be created nor destroyed but can be transformed from one form to another. Let us now prove that the above law holds good in the case of a freely falling body. Let a body of mass 'm' placed at a height 'h' above the ground, start fa..

In 1869, Mendeleev classified the then known 56 elements on the basis of their physical and chemical properties in the increasing order of the atomic masses, in the form of a table. Mendeleev had observed that properties of the elements orderly recur in a cyclic fashion. He found that the elements..
