Correct answer only !

on a cold winter morning, sound travels at only 330 m/s. you yell “hello” to your neighbor and they hear you after 0.40 seconds. how far away is your neighbor?

use the equation v=dt.

(hint: make sure you plug your numbers in for the correct variables! )

Velocity = distance / time

So: The time in which the wave propagates through air which is its medium along with the distance the wave travels so a point are needed to give us our velocity.

In this case we only have velocity and time

So lets rearrange our equation to fit what we are solving for: distance

Vt = d

Now plug in our values:

(330)(0.40) = d

d = 132 m

So the distance between you and your neighbor is 132 m as they perceive the sound at time t= 0.4 and a speed of sound of 330 m/s.

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
