Soddy and Fajan summarised the a and b - particle emission in the form of the law known as Group Displacement Law. "The emission of a - particle by an element results in the formation of a new element which lies two places to the left of the parent element an..

Halogens are the most electronegative elements. Fluorine is the most electronegative, followed by chlorine then bromine and then iodine. Fluorine being the most electronegative halogen can displace all the other elements of this group (chlorine, bromine and iodine) from the aque..

Lindemann (1942) put forth ten percent law for the transfer of energy from one trophic level to the next. According to the law, during the transfer of organic food from one trophic level to the next, only about ten percent of the organic matter is stored as f..

This is a reaction in which an atom or a group of atoms present in a molecule gets displaced by another atom. a) Displacement of a less active metal by a more reactive one i) When a piece of iron is added to a solution of copper (II) sulphate, iron displaces..

. The acceleration produced in the Earth being very small, the displacement of the Earth is negligible whereas in the case of the stone, the acceleration produced is very large and hence we see the stone moving towards the Earth. This example shows that Newton's third law..

Boyle's Law Robert Boyle proposed this law in the year 1662, giving the relationship between pressure and volume of given mass of a gas at constant temperature. This law states that volume (V) of a given mass of gas is inversely proportional to the pressur..

The incident ray, the reflected ray and the normal at the point of incidence lie in the same plane. The angle of incidence is equal to the angle of reflection. gives the number of images formed when the mirrors are inclined at an angl..

Laws of Refraction - The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane. For any two given pair of mediums, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. The above la..
