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.

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.

5. why should the electrons be placed separate from each other (why not together)?
