 Factors affecting photosynthesis Light  Without light, a plant cannot photosynthesize very quickly, regardless of whether there are water and CO2 or not. But overdoing light is also not a good idea. In nature, balance is crucial. But increasing the intensity of light to a prudent limit will speed up the process. Carbon Dioxide … Read more Factors Affecting Photosynthesis (2)

 Determinants of Nuclear Tests: Pokhran I (1974) and Pokhran II (1998) Pokhran 1 test The emergence of China as fifth nuclear power in October 1964 constituted a significant threat to India’s territorial integrity and sovereignty. The strained relations between the two countries after the 1962 aggression sparked off an acrimonious debate on defence … Read more Determinants Of Nuclear Tests

 Fuels are any material that store potential energy in forms, which upon burning in oxygen liberates heat energy. Calorific value of fuel is the total quantity of heat liberated when a unit mass or volume of fuel is completely burnt. Higher or gross calorific value (HCV) in the total amount of heat produced … Read more Ideal Fuel Properties

 Elementary idea of LASER Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. Many different types of lasers have been developed, with … Read more Elementary Idea Of LASER

 Importance of Science & Technology as an engine for national development- Industrial development & Urbanization Professor Freeman J. Dyson, of Institute of Advanced Studies, Princeton, in his book “Infinite in all Directions,” had this to say about Technology: “Technology is a gift of God. After the gift of Life, it is perhaps the … Read more Importance Of Science & Technology As An Engine For National Development Industrial Development & Urbanization (1)

 Electric current Ohm’s law and Resistance   Electrical current is the flow of charged particles. The flow of charges will be constant in current electricity. Electric current flows from higher electric potential to lower electric potential. For the current to flow, it requires a circuit which is closed loop of a conducting material. … Read more Ohms And Resistance

 Reproduction and growth – type of reproduction Living things grow and they reproduce. Growth is a way to generate the materials for reproduction. Reproduction is a way to make new organisms that can grow. Thus, the apparent “goal” of every organism is to fill the available world with its offspring, that is, with … Read more Reproduction And Growth
