Give reason We have two identical metal sheets. One of them is rubbed with sand paper and the other with ordinary paper. The one rubbed with sand paper shines more than the other.

Answer

The friction between sand paper and metal sheet is very large, compared to that between the ordinary paper and the metal sheet. Thus, the sand paper is able to remove the outer dull layer from the metal sheet more effectively and makes it more shining.
