Question

take 4 marbles rap 1 marble with chocolate paper second one with aluminium foil and third one with Sandpaper leave the fourth marble without a wrap now roll these Marbles on a smooth surface and measure the time they take to cross A certain distance not down your findings and correlate them with friction​

Answer 1

Answer:

answer is in explaination.

Explanation:

Let the Marble with Chocolate be M1 and F1 be the coefficient of friction.

and Marble with aluminium foil be M2 and F2 be the coefficient of friction. .

and Marble with Sandpaper leave be M3 and F3 be the coefficient of friction.

and Mable with no wrap be M4 and F4 be the coefficient of friction.

As distance travelled is inversely proportional to coefficient of friction.

and

F3 > F2> F1> F4.

so distance travelled will be

M4> M1> M2> M3.
