Applications of Newton's Second Law of Motion - In a cricket match a fielder moves his arms back while trying to catch a cricket ball because if he tries to stop the fast moving ball suddenly then the speed decreases to zero in a very short time. Therefore the retardation of the ball will..

Application of Plane Mirrors - Periscope - It is an instrument in which plane mirrors are used to fold light so that the image of an object can be brought down to a lower level. It is used for observing enemy movements from trenches without any danger of being seen. Sailors on submarines ..

The heating effect of current is utilized in electrical heating appliances such as electric iron, room heaters, water heaters, etc. All these heating appliances contain coils of high resistance wire made of nichrome alloy. When these appliances are connected to power supply by insulated copper wire..

Stokes' law explains why the speed of a raindrop is less than a freely falling body with constant velocity, from the height of clouds. The same law helps a man coming down with the help of a parachute, to slow down. Terminal velocity refers to the constant velocity, acquired by a freely fallin..

We know that the moon revolves around the Earth in a circular orbit and the Earth revolves around the sun in an elliptical orbi..

In a cricket match a fielder moves his arms back while trying to catch a cricket ball because if he tries to stop the fast moving ball suddenly then the speed decreases to zero in a very short time. Therefore the retardation of the ball will be very large. As a result the fielder has to apply a lar..

Gibberellin induces stem elongation in rosette plants. Cabbage is a rosette plant with profuse leaf growth and retarded internodal length. Just prior to flowering, internodes elongate enormously. This is called bolting. Bolting needs either long days or cold nights. When a cabbage head is kept unde..
