Graphite is a naturally-occurring form of crystalline carbon. It is a native element mineral found in metamorphic and igneous roks. It is extremely soft, cleaves with very light pressure, and has a very low specific gravity.
Water is made up of two elements. They are Hydrogen and Oxygen. There are 2 Hydrogen molecules bonded to 1 Oxygen molecule. Thus, the chemical formula of water is H2O ( Dihydrogen monoxide .....
Gravitaitonal field intensity is defined as gravitational force experiend per unit mass. ie. Gravitational foeld intensity (I) = F/m where F = GMm/R2 so, I = GM / R2 For calculation of gravitational field intensity can be calculated using .....

You may have seen seeds dispersed on ground and covered with mud. When water is plentiful, the seed fills with water. The water activates special proteins, called enzymes, that begin the process of seed growth (germination) As a result, a new .....
The solar wind is a stream of energized, charged particles, primarily electrons and protons,flowing outward from the Sun, through the solar system at speeds as high as 900 km/s and at a temperature of 1 million degrees Celsius. It is made of .....
Mineral oil is a colorless and odorless oil that's made from petroleum—as a by-product of the distillation of petroleum to produce gasoline. Mineral oil is also used to treat certain scalp .....
Since acceleration due to gravity depends on the radius of the planet. Value of radius is more at the equator, so gravity is camparatively less than that at the poles. As, gravity at poles is more, so object will reach the earth at .....
Matter is made up of atoms and molecules (groupings of atoms) and energy causes the atoms and molecules to always be in motion - either bumping into each other or vibrating back and forth. The motion .....
