Question

(b) You are holding a book in your hand. Are the particles of the book vibrating? Justify. [2]​

Answer 1

Explanation:

A book is a form of solid state of matter. In case of solids, even under stationary position, the particles move around their mean position. In solids, particles are attracted to each other and do not move too much but they do move such that they don't cross other particles. So even if you are holding a book in hand, its particles will follow its routine movement
