Question

Why is a rubber band considered as a solid?
A.It takes the shape of the container.
B.It has fixed volume.
C.It has negligible compressibility.
D.It changes shape under force and regains the shape when the force is removed.

Answer 1

Hint:In this question first, we will learn about the particles in an object, the force of attraction on the particles, how the particles are bounded by the force of attraction in an object. Based on the bonding of the particles we discuss the elasticity of a particular object.

Complete step by step answer:
The particles of the elastic band are inexactly limited by force of attraction, so as we stretch it moves to the greatest elastic limit and when it is delivered it recaptures its shape, accordingly, it has some property of solids.
And hence option D is the correct answer.

Additional information
What is meant by force of attraction?
Force of Attraction is the powers which intercede interaction between molecules, including powers of repulsion which act among ions and different sorts of neighboring particles
What is elastic force?
The elastic force happens as a deformed item (think spring) attempts to re-visitation of its unique shape. The power consistently acts towards a path that will restore it to its unique shape.
Hooke's Law depicts the number of objects that will create a more prominent power in direct extent to the measure of deformation.
Formula of Elastic force is:
$F$ = $k\Delta x$
Where,
$F$ is Force – This is restoration exerted by the object.
$k$ is Spring Constant – $\dfrac{N}{M}$ - This shows to which extent can a string be stretched.
$x$ is Stretch of the Spring

Note:
You need to remember the elastic limit values to answer the above question. You need to know about the force of attraction between particles in an object and how that force of attraction affects the body’s elasticity.
