to make a rubber ball travel longer distance on wooden surface,we should-a.cover the ball with piece of cloth b.sprinkle sand on the wooden surface c.sprinkle talcum powder on the surface d.spread carpet on the wooden surface
Answers
correct answer is (c) i.e. We should sprinkle talcum powder on the surface of the table which will smoothen the table surface reducing friction between the ball surface and table surfaces.
This will result and enable the rubber ball to travel longer distance on the wooden surface of the table which has become silk smooth.
ANSWER:
Sprinkle talcum powder on the surface.
EXPLANATION:
According to the friction formula of a sliding body,
F=μN
where
μ is the coefficient of friction, N is the reaction force and F is the force applied on the body.
If the force applied on the body is near to that of the reaction force, then the body might go long distance as the friction has become nonexistence.
We know that talcum powder is an excellent source of friction removal therefore to move an object on the surface for a longer distance while touching the surface can only be done by reducing the surface friction to negligible, so that there is approximately no opposing force, thereby making the rubber ball to go farther distances.
