. 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

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.
