standard unit for work

When pure and dry H 2 gas is passed through the inlet tube, a part of the gas gets adsorbed and the excess bubbles out through the perforations. Between the H 2 gas absorbed on the surface of the metal and H + of the solution, an equilibrium is established and an electrical double layer of oppo..

When a current is passed through the coil in the direction PQRS, then the coil experiences a torque t = NIBA sin a Since the magnified field is radial the plane of the coil is parallel to the magnetic field such that a = 90 o and hence t = NIBA. The coil rotates and the phosphor bronz..

W = F x S SI unit of F is N and that of S is m [N = newto..

One joule is the work done, when the point of application of a force of one Newton moves through a distance of one meter in the direction of forc..

SI Unit of Work - W = F x s SI unit of F is N and that of s is m [N=Newton] 1Nm is defined as 1 joule. i.e., 1 joule = 1..

Power is denoted by the letter 'P'. SI unit of power SI unit of work is joule and time is second. Therefore, SI unit of power is joule/second. 1 joule/second = 1 w..

Work and Heat - In 1798, Count Rumford observed that the amount of heat produced is proportional to the amount of mechanical work done. Later, Dr. James Prescott Joule of Manchester, established a definite relation between the work done and the heat produced. It was sh..

The minimum amount of energy required to emit electrons from a metal surface is called the work function or threshold energy of that metal. The number of electrons emitted per second i.e. the rate of emission depends upon the material of the surface temperature of the surface area..

The maximum height of mercury, which can be supported by the atmospheric pressure provides a measure of that pressure. A standard pressure of one atmosphere (1 atm) is defined as the pressure that will support a column of mercury of 76 cm height at 0C (density of mercury (13.5951 gcm - ..
