Ms. Elizabeth pushes a trash can and it moves across the cafeteria floor. Draw a free body diagram below. Label each force: force of gravity, friction, normal force, applied force, spring force, tension
force. Not all used here.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
