Viscous force is somewhat like friction as it opposes the motion and is non-conservative but not exactly so because

Options

A. It is velocity dependent while friction is not
B. It is velocity independent while friction is not
C. It is temperature dependent while friction is not
D. It is independent of area while friction is dependent

Answer

ac

Explanation

Friction is independent of velocity and temperature. Viscous force depends on temperature as `eta` varies with temperature.
