Physics - ICS Part 2 Physics Chapter 17 Short Questions Preparation

Question # 1

Distinguished between elasticity and plasticity.

  • Ans 1: Elasticity: In deformed crystalline solid,the atoms return to their equilibrium position after the removal of external force.This ability of the body to return to its original shape is called elasticity.
  • Ans 2: Plasticity:If the stress is increased beyond elastic limit,the specimen becomes permanently deformed.This is called plasticity.

Question # 1

Distinguished between soft magnetic material and hard magnetic materials.

  • Ans 1: Soft magnetic: The materials in which their domains can be easily orientated on applying external magnetic field and also return to original positions when field is removes.E.g iron.
  • Ans 2: Hard magnetic:The material in which their domains can not easily orientated on applying external magnetic field.But once the domains are lined up by a very strong magnetic field,they will restrain their position after the removal of magnetic field.
