Question

please tell the correct answer please
I will mark as Brainlist him or her​

Answer 1

Answer:

here is the answer:-

1.The frictional force between two bodies depends mainly on three factors: (I) the adhesion between body surfaces (ii) roughness of the surface (iii) deformation of bodies.

2.Shyam’s suggestion of keeping iron bar below the box will help the labour more. Putting the iron bar below the box will make it to roll over the bar. As rolling friction is less than sliding friction, it will help in moving the box with much easier.

3.Putting the iron bar below the box will make it to roll over the bar. As rolling friction is less than sliding friction, it will help in moving the box with much easier.

4.Nature of surfaces in contact, weight of the object, force of adhesion and deformation.
