Answer 1

Answer:

wet marble floor, dry marble floor, newspaper and towel.

Explanation:

Force of friction depends on the nature of surface in contact. The rougher the surface, the more is the friction between the surfaces in contact and vice-versa. Roughness present in the given surfaces can be arranged in an ascending order as wet marble floor, dry marble floor, newspaper and towel.

Hence, the correct sequence of these surfaces when arranged according to the increase in the force of friction acting on the car is - wet marble floor, dry marble floor, newspaper and towel.
