The diagram shows changes of state between solid, liquid, and gas. the atoms of a substance gain energy during a change of state. before the change, the atoms are close together and cannot slide past one another. after the change, the substance can fill its container. which arrow represents the change of state described above? l m n o

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell

Amagnetic field applies forces on: a)static chargesb)moving chargesc)water flow

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.
