From times immemorial, man has used machines to help him in his work. Today, we are dependent on machine for almost every task. When we think of machines we always tend to think of big and complicated units with many moving parts like wheels and rollers and gears and shafts. In Phys..

To start with, suppose the plane of the coil is perpendicular to the plane of the paper in which the magnetic field is applied, with AB at the front and CD at the back, the flux linked with the coil is maximum in this position. As the coil rotates clockwise, AB moves inwards and CD moves outwards...

Gregor Mendel was the first to carry out scientific studies on transmission of characteristics from the parent to the offspring. He selected garden peas as they showed many contrasting traits that were easy to track through the generations. Moreover, these plants are naturally self-pollin..

The Environment is everything which surrounds an organism and influences its life in many ways. It includes physical and biological components. The physical components of the environment are soil, water, air, light and temperature. These are termed as abiotic components. The plants and animal..

According to wave theory when light falls on a metal surface, energy is continuously distributed over the surface. All the free electrons receive light energy and when the energy received exceeds that of work function, an electron may escape the surface..

Crude rubber is a tough and elastic solid. It becomes soft and sticky as the temperature rises. Its specific gravity is 0.915. The most important property of natural rubber is its elasticity. When stretched, it expands and attains its original state, when released. This is due to ..
