On which of the following factors fluid friction does not depend?
-
Speed of body
-
Shape of object
-
Nature of fluid
-
Nature of object
D
Correct answer
Explanation
Fluid friction depends on: speed of body (higher speed = more drag), shape of object (streamlined shapes reduce drag), and nature of fluid (more viscous fluids create more resistance). It does NOT depend on the nature (material/composition) of the object itself.
