what a piece of work is man meaning

The ray diagram given below gives the principle of a compound microscope. The object is mounted on the stand below the microscope tube. The objective lens forms a real, inverted and magnified image (I 1 ) of the object. The image I 1 acts as an object for the eye piece. The position of th..

Introduction - For a layman the term 'work' implies any activity resulting in muscular or mental exertion. In physics, however, the term has a different meaning. It represents a physical quantity. When a force acts on an object, if the object moves in the direction of force, we ..

A piece of work can be done by 54 men in 16 days. In how many days can 9 men do the same piece of work? => 98 or 96 or 54 or none of the above..

Machine - 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 s..

When the applied force and the displacement make an angle 90 o to each other, the work done is zero. This is because cos 90 = 0. A person carrying a briefcase, moves on a horizontal road. Since, the gravitational force acts vertically downwards and the displacement of the person is in..

(i.e., the magnitude and the direction of the force do not change.). Work is the energy transferred to or from an object by means of a force acting on the object. Energy transferred to the object is positive work and energy transferred from the object is negative ..
