Students drop objects from a height and measure the time it takes each object to reach the ground. What is the dependent variable in the experiment? A) falling time b) shoe c) drop height d) paper

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.
