Using the focal point and the optical axis, you can diagram how some of the light rays that travel to a concave mirror are reflected. True or false?

Which describe reflection? check all that apply. light bounces off a boundary.

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
