Question

Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a man accidentally stubs his toe. About how much time does it take the nerve impulse to travel from the foot to the brain (in s)? Assume the man is 1.80 m tall and the nerve impulse travels at uniform speed.

Answer 1

t = 0.018 s

Step-by-step explanation:

given,

nerve impulse in human body travel at a speed of = 100 m/s

height of the man = 1.80 m

time taken by the impulse to travel from foot to brain = ?

distance = speed × time

1.80 = 100 × t

t =
`(1.80)/(100)`

t = 0.018 s

hence, the time taken by the nerve to reach brain from toe is 0.018 s
