Question

5. People often rub their hands in winter. Why?
6. Why Pluto is not considered as planet?​

Answer 1

Answer:

5) When we rub our palms, friction is produced and in turn we feel warmth due to the production of heat. So, to get warmth we rub our palms during winters.

6) The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighbouring region of other objects.”
