Question

Which of the following is/are factors of fluid friction?

• A. The shape of the body moving through the fluid.
• B. The speed of the body moving through the fluid.
• C. The density of the fluid.
• D. The colour of the fluid.

Answer 1

Answer: (A), (B), (C)

The correct options are
A The shape of the body moving through the fluid.
B The speed of the body moving through the fluid.
C The density of the fluid.

Fluid friction depends on the speed and shape of the body moving through the fluid. It also depends on the density of the fluid. However, the colour of the fluid does not affect fluid friction.
