In order to achieve very large amounts of plastic strain in a forming operation, we should a) cold work at a temperature above 0.4 t b) cold work at a temperature below 0.4 tm e) hot work at a temperature above 0.4tm d) hot work at a temperature below 0.4 t e) none of these

Two microscope slides are placed horizontally, one on top of the other, with a drop of a dishwashing liquid between them. the gap between the slides is 1 mm. a machine pulls the top slide to the right with a velocity of 0.15 millimeters per second while the bottom slide is held stationary. a stress gage indicates that a shearing stress of 0.5 pa is required to pull the top slide with this velocity. if the dishwashing liquid adheres to both slides during this process, what is the viscosity of the liquid? specify whether your answer is dynamic or kinematic viscosity, and use appropriate units.
