Scattering is a general physical process whereby some forms of radiation, such as light or moving particles, for example, are forced to deviate from a straight trajectory by one or more localized non-uniformities in the medium through which it passes. A large number of molecules are ..

If the area of a triangle is equal to one fourth the product of the lengths of two sides, then find the included angle? => 45° or 30° or 120° or 60° or 90° or 90° or 30°..

1) Oxygen is mainly produced during photolysis of water in the light phase of photosynthesis during which molecular oxygen is released into the atmosphere for reuse in respiration. 2) Oxygen is made available to the environment in combination with carbon in the form of carbon dioxide (by..

Crop Production - Crop improvement technologies improve the potentialities of higher yield and food quality in crops. New varieties and hybrids of various crops released by various crop improvement techniques are ultimately aimed to increase the yield and better quality. But, these potent..

When the pressure of air in the discharge tube is reduced to .001 mm of mercury and a high voltage is applied to the electrodes, the emission of light by air stops. But the phenomenon of fluorescence is observed in which the walls of the discharge tube at the end opposite to the cathode b..

Goldstein experimentally proved the existence of positive charge in matter. In his experiments, a perforated cathode was used in a discharge tube along with air at very low pressure of about 0.001 mm of mercury. When a high voltage of about 10,000 volts was applied to this cathode in the discharge..

(milch) animals like cows, buffaloes and goats. Eggs are obtained from egg laying birds like fowl and duck. Meat is obtained from fowl, cow, sheep, goat and pig. Fish are either fresh water or marine and include crabs, shrimps and prawns. To meet the ever-increasing demand of food to feed..

The Sun radiates energy in the form of heat and light. We utilize these forms of energy either directly or indirectly, after conversion into some other forms. Utilization of solar energy in various ways is as represented. Besides the primary role of the Sun's energy, it is now belie..

Maximum yield of eggs is obtained by keeping the poultry in comfortable, well ventilated, dry, clean and properly lighted houses. Birds of different ages should be kept separately. The first phase in the life of poultry is called the growing period and the chickens are called growers. Dur..

This factor includes rainfall, temperature, light, wind and humidit..
