Question

You step onto a hot beach with your bare feet. A nerve impulse, generated in your foot, travels through your nervous system at an average speed of 103 m/s. How much time does it take for the impulse, which travels a distance of 1.87 m, to reach your brain

Answer 1

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

$=\frac{1.87}{103}=0.018sec$

So it will take 0.018 sec to complete 1.87 m
