Fluid resistance to shear depends upon its_______________?
Correct answer: C. Both A. and B.
- A. Rate of transfer of molecular momentum
- B. Cohesion
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Shear resistance arises from molecular momentum transfer between fluid layers and from intermolecular cohesion. Therefore, both factors contribute to viscosity.
