Certain flowering plants have the capacity to develop a part of their somatic body into a new independent plant. In artificial vegetative propagation, such plants are identified and special techniques are applied to obtain new independent plant. Horticulture have ..

Solar Cooker - A solar heating device is one which allows collection of a large amount of heat from the sunlight in a given region and restricts the loss of heat to the surrounding in the form of radiation. The following facts help us to design an efficient solar cooker: A black body abso..

Newton's First Law of Motion - Every body continues in its state of rest or of uniform motion in a straight line unless compelled by some external force to act otherwise. It is a matter of common experience that objects at rest do not begin to move of their own accord. If we place an obje..
