This action potential is moving along the axon at 20 m/s in the positive direction.1.1 Sketch the shape of the action potential as a function of position at some arbitrary moment in time.1.2Label the features of your sketch (A, B, C, D, E).1.3 What is the approximate distance between points A and E on your sketch

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

The answer would be d. hope this : ))
