origin of mean

In electrostatic situations, the electric field is zero everywhere within the conductor, and there is no current. This does not mean that all charges within the conductor are at res..

In electrostatic situations, the electric field is zero everywhere within the conductor, and there is no current. This does not mean that all charges within the conductor are at rest. In metals such as copper or aluminium, some of the electrons are free to move within the conducting mate..

Colored substances used for dyeing fabrics are called dyes. A true dye must: Have a suitable color Be able to attach itself to the material from solution or be capable of being fixed on it Be fast to light and washing when fixed. For this it must be resistant to water, acid and alkali Graebe and Li..

, called the moment of inertial of the body about the axis of rotation. Let us note the similarity between 'm' is the mass of the body and does not depend on the choice of the origin or the axes of rotation or the kind of motion. But, the moment of inertia depends on the choice of axis. Ho..

The statement "If each value in a set of data is multiplied by a constant ' a ' and is decreased by a constant ' b ', then the mean of the new set of data is equal to ' a ' times the mean of the original set of data decreased by a constant ' b ' ", is _______.Use follo..

We are familiar with plane figures bounded by straight line segments as sides. They are known as Polygons . Polygon is a word of Greek origin. It means figure with many angles implying many sides. Squares, rectangles and other four-sided geometric figures formed by the union of ..

Population is the next level in ecological hierarchy the word population has its origin in the Latin word populus meaning 'people..

A collision is said to be an inelastic collision if the kinetic energy is not conserved in the collision. However the momentum is conserved. The kinetic energy lost in the collision appears in the form of heat energy, sound energy or light energy. The forces of interaction in an inelastic collision..

The word 'geometry' is derived from the Greek words 'geo' meaning 'earth' and 'metron', meaning 'measuring'. Geometry originated when man felt the need to measure his land. Ancient Egyptians were perhaps the first people to study geometry. Later, the Babylonians studie..
