viscosity ?
(A)
Potential energy stored in fluid
(B)
Resistance to fluid motion
(C)
Roughness of the surface
(D)
None of the above​

Answer 1

Answer:

resistance to fluid motion is the correct answer.

hope it helps!!!

Answer 2

The following represents viscosity (D)None of the above​

Explanation:

• Often, the easiest way to answer this question is to give an example. Consider a styrofoam cup with a hole in it. When I pour honey into the cup, I notice that it drains quite slowly. This is due to honey's high viscosity when compared to the viscosities of other liquids.
• Filling the same cup with water, for example, causes the cup to empty substantially faster.
• The viscosity of a fluid is a measurement of its resistance to flow. Internal friction of a moving fluid is described by this term. Since of its molecular constitution, a fluid with a high viscosity opposes motion because it has a lot of internal friction.
• When a fluid has a low viscosity, it moves readily because its molecular nature causes very little friction.Gases have viscosity as well, albeit it's a little difficult to observe in everyday life.
