If average speed is calculated using the equation, "distance traveled/elapsed time," what is the average speed of an object that travels 65m in 5s?

13m/s

Explanation:

The speed= distance traveled/elapsed time

Therefore speed=65/5

=13m/s

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.
