Question

8. Give reason for the following:
a) Gymnasts apply a coarse substance on their hands.
b) While playing carom board, we apply talcum powder.
c) Heavy luggages equipped with wheels.

Answer 1

Answer:

8. a) Gymnasts apply a coarse substance on their hands to get a better grip on objects. The course substance makes their hands' surface rougher, which provides more friction required for weight lifting and dangling with bars.

b) While playing carom, talcum powder is applied on the board because talcum is one of the finest substance in the world so it can easily fill the rough areas of the board, and thus can give an ideal platform for playing carom with less friction.

c) Heavy luggages are equipped with wheels so as to minimise the friction between the luggage and the ground, and thus to facilitate easier transportation of heavy luggages.
