Please answer extra points—From the rules that a good absorber of radiation is a good radiator and a good reflector is a poor absorber, what can you say about the relationship between the ability to reflect and radiate energy?

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.
