Answer:
It will take 0.018 sec to complete 1.87 m
Explanation:
We have given speed of the nerve impulse in the nervous system is 10.3 m/sec
Distance traveled by nerve impulse s = 1.87 m
We have to find the time taken by nerve impulse to complete this distance
We know that time is ratio of distance traveled and average speed
So time taken by nerve impulse to compete 1.87 m will be equal to
So it will take 0.018 sec to complete 1.87 m
Answer:
v = wavelength * frequency
frequency = 5200 m/s / .2 m = 26000 / sec
20,000 / sec is optimistic for the upper frequency of human hearing
So 26,000 is above the hearing range for human ears
