multiple question question of physical chemistry question

The study of structure of atoms, radioactivity, X-ray, diffraction, etc., in physics has enabled chemists to rearrange elements in the periodic table and to have a better understanding of chemical bonding and complex chemical structure..

Coulomb's law describes only the interaction of two point charges. Experiments show that when two charges exert forces simultaneously on a third charge, the total force acting on that charge is the vector sum of the forces that the two charges would exert individually. This important property..

When an object is kept between two plane mirrors inclined at an angle q , more than one image forms. The total number of images formed in such a case can be related to the angle as follows :..

The multiplication of a vector by a real number assumes a lot of significance in such statements as - velocity of car B is double the velocity of car A l..

Introduction - Humans have always been curious about the world around them. The world has an astonishing variety of materials and bewildering diversity of life and behaviour. The inquiring and imaginative human mind has responded to the wonder and awe of nature in different ways. This human endeavo..

Arithmetic operations such as addition, subtraction and complex operations such as multiplication, division etc., are performed by using digital circuits called adders, which again consists of basic logical gates. Repeated addition gives multiplication. Repeated subtraction give..

It was mentioned earlier that, displacement vectors are added to displacement vectors, or velocity vectors are added to velocity vectors. Just as it is meaningless to add scalar quantities of different kinds, such as mass and temperature, so also it is meaningless to add vector quantities of diffe..

It is a device which helps us to do the work at one point and deliver at another point with a view of accomplishing the work more easily or with a gain in speed. We use machines to multiply force or to change the direction of the force or to increase or decrease the speed etc. Cutting pliers, claw..
