Answer:
Speed of a car and the distance from earth to sun are the only physical quantities, as they both can be measured and expressed in terms of fundamental quantities. But, how angry a person is or how much a mother loves her child are the emotions and can not be measured or expressed in terms of fundamental quantities. So, they are not physical quantities.
