a) smooth
b)rough
c) very rough
d) none of these

Answer 1

Answer:

The use of lubricants makes the surface

(a) => Smooth.

On applying lubricants , the area of contact between the two surfaces is reduced , resulting in the reduction of friction too.

Explanation:

Answer 2

The use of lubricants makes the surface smooth.

Explanation:

1. The correct answer of the asked question is Option A.

2. Lubricants helps to make the surface smooth by reducing friction of the surface.

3. Example of lubricant is grease. Lubricants may be available in the form of solid, plastic substances or even in fluid form.

4. Lubricants allows the surfaces to slide on one another very smoothly without any friction.

5. We can find the application of lubricants in the machines where it is applies in the machine's rubbing surfaces. This helps to remove the roughness of the surface and reduces friction to a great extent which then helps the machine to work smoothly and properly.

6. Those lubricants are good which has high viscosity.
