unit of 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 ..

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..

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..

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..

Paula earned $84 for 14 hours of work. Find the unit rate. => $7 per hour or $5 per hour or $6 per hour or $8 per hour..

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..

A manufacturer makes two models A and B of a product ,each should be processed by two machines. To complete one unit of model A, machines I and II must work 1 hour and 2 hours respectively. To complete one unit of model B, Machine I and II must work 4 hours a..
