The correct answer is B. Nitrogen
Answer:
235 ms
Explanation:
- First of all, let's calculate the time the sound takes to travel through air a distance of d=10 m. The speed of sound in air is v = 343 m/s, so we have
- Then, we have to add the detection time of the ear:
- Then, the time the nerve impulse takes to travel from the ear to the brain (speed v=120 m/s, distance d=10 cm=0.01 m):
- Then, the brain processing time:
- Then, the time the nerve impulse takes to travel from the brain to the muscles (speed v=120 m/s, distance d=75 cm=0.75 m):
- Finally, the reaction time of the muscles:
Summing all together:
