Q. Define Viscosity.

  • (A) resistance to flow of object
  • (B) resistance to flow of air
  • (C) resistance to flow of fluid
  • (D) resistance to flow of heat
💬 Discuss
✅ Correct Answer: (C) resistance to flow of fluid
Explanation: viscosity is developed due to the relative motion between two surfaces of fluids at different velocities. it happens due to the shear stress developed on the surface of the fluid.
