Question

Which of the following statement (s) is/are correct about viscosity?

A.It is a measure of its resistance to gradual deformation by shear stress or tensile stress.

B.It is typically measured in dynes/cm, the force in dynes required to break a film of length 1 cm.

C.It is the ability of a body to resist a distorting influence or stress and to return to its original size and shape when the stress is removed.​

Answer 1

Explanation:

Option A is correct

It is the measure of its resistance to gradual deformation by shear stress or tensile stress.

Thank you

Answer 2

Answer:

Option(A)is the correct answer.

Explanation:

• The resistance of a fluid (liquid or gas) to a change in shape or motion of adjacent sections relative to one another is known as viscosity.

• The right response is viscosity. Viscosity, a measurement of flow resistance brought on by internal friction between fluid layers, The majority of fluids have some motion resistance.

• This opposition to fluid motion is comparable to internal friction that occurs when a solid moves across a surface.
