A 2.4kg toy falls from 2 m to 1 m
What is the change in GPE?

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

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.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
