Aringing bell is sending a longitudinal wave to your ear. what else is true about the longitudinal wave? check all that apply. all sound waves are longitudinal. energy is transferred perpendicular to the wave’s motion. mechanical waves can be longitudinal. electromagnetic waves can be longitudinal. longitudinal waves require a medium to travel through.

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.
