Electroplating is very useful because of the following reasons: Surface protection e.g. nickel plating of iron to prevent corrosion. Makes the article attractive e.g., electroplating of silver or gold on brass etc. Repair of finer machine parts..

Friction as a Contact Force - In real life an object which is moving over a horizontal surface does not continue with constant velocity when the accelerating force is removed. Instead the object slows down and eventually stops. The deceleration is caused by a frictional force between the object and..

1 and B 2 . When the coil rotates, the split rings rotate but the brushes do not move. A wheel can be mounted on the axle placed along the axis of the coil so as to drive the desired parts of the machine such as electric fan, washing machine etc. where the motor is u..

Humans can only live about five minutes without air. Dry air is generally a homogeneous mixture (solution) of nitrogen gas (78%), oxygen gas (21%), and traces of other gases. Some of the other gases are waste products of human activities and are known as air pollutants. Air pollution may be defined..
