A stretched rubber has :

A wire suspended vertically from one of its ends is stretched by attaching a weight of 200 N to the lower end. The weight stretches the wire by 1 mm. Then the elastic energy stored in the wire is:          

The Young's modulus of the material of the wire of length $$L$$ and radius $$r$$ is $$Y{ N }/{ { m }^{ 2 } }$$. If the length is reduced to $${ L }/{ 2 }$$ and radius $${ r }/{ 2 }$$, the Young's modulus will be:

In a technical sense a substance with a ________ elasticity is one that requires a ______  force to produce a distortion-for example, a steel sphere. 

The Bulk modulus for an incompressible liquid is :

Which of the following is an example of elastic deformation?

The property to restore the natural shape or to oppose the deformation is called :

In plastic deformation, deformation is 

The bulk modulus of elasticity with increase in pressure 

The property of a material due to which shape is changed permanently is known as:
