. You conducted an experiment in the lab to determine the viscosity of a Newtonian fluid between two concentric cylinders. The diameter of the inner cylinder is 33 mm and that of the outer cylinder is 36 mm. You rotated the inner cylinder, which is 36 mm in length and completely submerged in the fluid, at 7000 rpm and found the torque to be 0.04 Nm. What viscosity (cP) did you get if you neglected viscous effects at the ends of the inner cylinder and also assume the space between the two cylinders can be modeled as two parallel plates separated by a fluid

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
