What type of fluid behavior is observed when there are deviations from the linear plot between viscosity and shear rate?*2 pointsNewtonian behaviorNon-Newtonian behaviorViscous behaviorInertial behavior

A small ball is held at the surface of liquid oil in a container. The ball is released from rest andfalls through the oil. The ball has velocity v. A viscous (drag) force F acts on the ball.Which graph could show the variation with v of F?

Newton’s law of viscosity states thata.the shear stress applied to the fluid is directly proportional to the  specific weight of the fluidb.  the shear stress applied to the fluid is directly proportional to the velocity gradient du/dyc.the shear stress applied to the fluid is inversely proportional to the velocity gradient du/dyd.    the shear stress applied to the fluid is directly proportional to the  specific weight of the fluid
