Question

Give reasons for the following :
(i) Treaded tyres are used in a car instead of flat tyres.
(ii) When we shake a wet piece of cloth after washing, water droplets come out of it.

Answer 1

Answer:

1) threaded tyres are used in a car to increase the friction between the tyre and ground.

2)When we shake a wet cloth, water droplets come off from it, because of inertia of rest. Water drops in the wet cloth were in a position of rest. When shaken, the cloth moves suddenly, but the droplets have a tendency to remain at rest owing to the property of inertia and they are detached from the cloth
