The ratio of the shearing stress to the velocity gradient (correct)

The force per unit area required to maintain a unit difference in velocity between two parallel layers of fluid

The measure of the fluid's resistance to shear or tensile stress

The ratio of the mass density of the fluid to the acceleration due to gravity

The weight per unit volume of the fluid (correct)

The measure of the fluid's resistance to shear or tensile stress
