•••Define viscosity???​

Answer 1

Answer:

important concepts within a document and make it more readable. Using italics, bold or underlined words can change the perception of the reader

Answer 2

the temporary resistance offered by the fluid to the shearing stress is called viscosity

Or

viscosity is that property of fluid due to which they opposes relative motion between the adjacent layer.

Newton found that the viscous force acting tangentially on a layer of a fluid is directly proportional to

• velocity gradient in a direction perpendicular to the layer
• the surface area of the layer

this law is called Newton's law viscous flow in streamline motion.
