In order for an object to move in uniform circular motion, it must not be
accelerating
o a. true
ob. false

True.

Explanation:

Only in acceleration will objects move at different speeds.

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.
