The viscosity of a fluid is to be measured by a viscometer constructed of two 60-cm-long concentric cylinders. the outer diameter of the inner cylinder is 15 cm, and the gap between the two cylinders is 1 mm. the inner cylinder is rotated at 300 rpm, and the torque is measured to be 0.8 n·m. determine the viscosity of the fluid.

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
