Alida runs her toy car on dry marble floor, wet marble floor, newspaper, and towel spread on the floor. The force of friction acting on the car on different surfaces in increasing order will be :​

The force of friction depends on the type of surface the object is moving on. In this case, the toy car is moving on different surfaces.

1. Dry Marble Floor: This surface is smooth and hard, so the force of friction would be the least on this surface.

2. Wet Marble Floor: The force of friction would be slightly higher on a wet marble floor compared to a dry one because the water creates a thin layer between the car and the floor, increasing the friction.

3. Newspaper: A newspaper is more textured than marble, so the force of friction would be higher on this surface.

4. Towel: A towel spread on the floor would have the highest force of friction because it is the most textured surface among the four.

So, the force of friction acting on the car on different surfaces in increasing order will be: Dry Marble Floor, Wet Marble Floor, Newspaper, Towel.
