Detailed Solution

Alida runs her toy car on a dry floor made of marble; wet marble floor, newspaper, and towels are spread on the floor. The friction force acting upon a car for different surfaces in increasing order will be wet marble floor, dry marble floor, newspaper, and towel.
The force that resists the motion between any surfaces in contact is known as friction. Rough surfaces have more friction than smooth surfaces, and liquids such as oil or water are sometimes used as lubricants to reduce the effect of friction. There is no mystery behind friction. It acts on objects on the surfaces to prevent or reduce movement between the surfaces. Compared to other surfaces, the toy car experiences less friction when running on the wet marble floor and more friction when running on the towel. Running on dry marble causes less friction than on newspaper. Therefore, a wet marble floor, dry marble floor, newspaper, and towel are in increasing order of friction produced.
