Question

7. Name the physical quantity that corresponds to the rate of change of momentum. Give its SI unit
8. The relative density of a substance is greater than 1. What does it signify?​

Answer 1

Answer:

FORCE

FORCE IS THE PHYSICAL QUANTITY WHICH CORRESPONDS TO RATE OF CHANGE OF MOMENTUM

If the density of a substance is greater than that of water it will sink in water so, if relative density of substance is greater than 1, then it signifies that it will sink in water or we can say that it is heavier than equal volume of water.

Hope this helps.
