Thermodynamics deals with the principles of heat and temperature and the inter-conversion of heat and other forms of energy. The four laws of thermodynamics govern

Most machines are created and developed to do deal with objects. All machines are typically described by a power rating. The power rating indicates the rate at which that machine can do work upon other objects.

It is among the four equations of Maxwell’s laws of electromagnetism. It was initially formulated by Carl Friedrich Gauss in the year 1835 and relates the electric fields at the points

Fluid Flow and Equation of Continuity Moving fluids are of great value. To find out about the behaviour of the fluid in motion, we consider their flow through the pipes. When a fluid is in motion, its flow can be either streamline or turbulent. The flow is stated to be streamlined or laminar, if every particle … Read more Fluid Flow and Equation of Continuity

A capacitor is a device that stores electrical energy or electric charge in an electrical field. It is a passive electronic component with two terminals.

The electroscope is an early scientific instrument used to detect the presence of electrical charge on a body. It finds charge by the motion of a test object due to the Coulomb electrostatic force on it.

This is a typical observation that the amplitude of an oscillating basic pendulum reduces slowly with time till it becomes zero. Such oscillations, in which the amplitude reduces gradually with time, are called damped oscillations.

When the source and observer are moving relative to each other, the frequency observed by the observer (fa) is different from the actual frequency produced by the source (f0).

The Bohr model was an improvement on the earlier cubic design (1902), the plum-pudding model (1904), the Saturnian model (1904), and the Rutherford model (1911).

Simple Harmonic Motion or SHM is defined as a motion in which the restoring force is directly proportional to the displacement of the body from its mean position.
