What is the value of the shear modulus of sulfuric acid?

When stirring with a spoon is stopped in milk,it comes to rest after some time. Why?

Water in a river $20 \ m$ deep is flowing at a speed of $10 \ ms^{-1}$. The shearing stress between the horizontal layers of water in the river in $Nm^{-2}$ is (Coefficient of viscosity of water $= 10^{-3} \ SI \ units$)

In a laminar flow,the velocity of the liquid in contact with the walls of the tube is:

The coefficient of viscosity for hot air is

When the temperature increases,the viscosity of
