Who noticed the deflection of the compass needle every time the current was passed through the wire? When an electric current flows through a wire, it behaves like a magnet.
By connecting a high resistance in series with the galvanometet
what is the difference between the two ?
pressure inside a liquid jet in excess of atmostpheric pressure . for example if aglass tube of samll diameter is partially immersed in water , the water will wet the surface of the tube ant it will rise in the tube to some height above the normal water surface . In this case, the water surface is concave upward.
In this collision
Coefficient of restitution 0 < e < 1
The loss in kinetic energy appears in other forms, such as heat, sound etc.
Ex- Collision between two billiard balls. All majority of collision belong to this category.
momentum is conserved whereas KE is not conserved as in elastic collision
