How is a pseudoscope different from a stereoscope microscope? (A)The images from the left and right eyepieces are reversed in a stereoscope microscope which inverts the 3D image vertically.
(B)A stereoscope produces a false 3D image that appears to be inverted from the original position.
(C)The images from the left and right eyepieces are reversed in a pseudoscope which inverts the 3D image vertically.
(D)A pseudoscope yields a 3D view that is reversed 60 degrees.

In a wind tunnel the speed changes as the cross sectional area of the tunnel changes. if the speed in a 6' x 6' square test section is 100 mph, what was the speed upstream of the test section where the tunnel measured 20' x 20'? use conservation of mass and assume incompressible flow. conservation of mass requires that as the flow moves through a path or a duct the product of the density, velocity and cross sectional area must remain constant; i.e., that ova-constant. a model is being tested in a wind tunnel at a speed of 100 mph if the flow in the test section is at sea level standard conditions, what is the pressure at the model's stagnation point? (a) the tunnel speed is being measured by a pitot-static tube connected to a u- tube manometer. what is the reading on that manometer in inches of water? (b) at one point on the model a pressure of 2058 psf is measured. what is the local airspeed at that point?

Ben (55kg) is standing on very slippery ice when junior (25kg) bumps into him. junior was moving at a speed of 8 m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision. give the answer in m/s. describe the work you did to get the answer.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
