The conduction velocity of an axon is determined by myelin sheath
thickness and internode distance.
Axon are structures in the neuron which is involved in the conduction of
impulses away from the cell body. Axons which have myelin sheath conduct
impulses faster than those without it.
Axons which have thicker myelin sheath and longer internode distance will
increase the conduction velocity of an axon and vice versa.

Answer:
Acceleration,
Explanation:
Given that,
Height from a ball falls the ground, h = 17.3 m
It is in contact with the ground for 24.0 ms before stopping.
We need to find the average acceleration the ball during the time it is in contact with the ground.
Firstly, find the velocity when it reached the ground. So,
u = initial velocity=0 m/s
a = acceleration=g
It is in negative direction, u = -18.41 m/s
Let a is average acceleration of the ball. Consider, v = and u = -18.41 m/s.
So, the average acceleration of the ball during the time it is in contact is .
