unit price work

Unit work is the amount of work done when a unit force displaces a body through unit distance in the direction of the force. In International System of units, the absolute unit of work is 'joule'. 1 joule = 1 newton x ..

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..

Summary - The essential conditions to be satisfied for work to be done are: Some force must act on the object The point of application of force must move in the direction of force W = F x S SI unit of work is joule Energy is the capacity to do work The two types o..
