To describe the phenomena related to magnets, lines are used to depict the force existing in the area surrounding the magnet. These lines are called the magnetic lines of force. These lines do not exist actually, but are imaginary lines that are used to illustrate and describe the pattern of the magnetic field. As shown … Read more
FSOC technology uses beams of light to deliver high speed, high capacity connectivity over a long distance. The energy beam is sent through clean air or space from the source to the destination, rather than guided through an optical fibre. As long as there is a clear line of sight between the source and the … Read more
Insat (Indian National Satellite System) was a multipurpose satellite system for telecommunications, broadcasting, meteorology and search and rescue services.

Chronic NCDs comprise diabetes, high and low blood pressure, cancer, chronic respiratory problems, mental disorders and cardiovascular diseases. Malnutrition and infection at early age prevalent in poor are important triggers for NCDs. Low literacy and inadequate information among people are the main cause for non- awareness about these chronic diseases. Status of burden of Non … Read more
It is light weighted and is one-third the weight of lead acid batteries. It is nearly 100% efficient in both charging and discharging as compared to lead battery which has 70% efficiency. It completely discharges i.e. 100% as compared to 80% for lead acid. It has life cycle of 5000 times or more compared to … Read more
There are several ways of removing particulate matter; the most widelyused of which is the electrostatic precipitator, which can remove over 99 per cent particulate matter present in the exhaust from a thermal power plant. It has electrode wires that are maintained at several thousand volts, which produce a corona that releases electrons. These electrons … Read more
Mendel’s laws Mendel discovered that, when he crossed purebred white flower and purple flower pea plants (the parental or P generation), the result was not a blend. Rather than being a mix of the two, the offspring (known as the F1 generation) was purple-flowered. When Mendel self-fertilized the F1 generation pea plants, he obtained a … Read more
