III. (3 pts) What is Newton's Law of viscosity? Write the mathematical expression with explaination for each term 2) An incompressible Newtonian liquid with a density of 850kg/m3 is confined between two horizontal parallel plates separated by a distance equal to 0.5cm. The top plate moves in the positive x-direction with a velocity of 10cm/s by applying a force of 0.0066N in the direction of motion. If the area of each plate in contact with the liquid is 200cm2, determine the viscosity of the liquid in units of Pas
