Answer:
Time taken t = 4.167 seconds (Approx)
Explanation:
Given:
Initial Speed u = 12 m/s
Final speed v = 0 m/s
Acceleration a = -50 m/s²
Find:
Time taken t
Computation:
v = u + at
0 = 12 + (-50)t
t = 4.167 s
Time taken t = 4.167 seconds (Approx)
It acts an insulator on the neurons. The neurons are covered with it and hence the nerve impulses have to jump over the myelin sheath to reach other neurons. This causes nerve impulses to move rapidly from neuron to neuron.
