For this case, what we can do is use the Pythagorean theorem to find the magnitude of the displacement of the car.
We have then
From here, we clear the value of d.
We have then:
Rewriting:
Answer:
The magnitude of the car's displacement is:
d = 20 miles
Answer:
0.83 m or 5.57 m
Explanation:
Destructive interference will occur when the distances from the speakers differ by 1/2 wavelength.
The length of 1 cycle of 72.4 Hz is ...
λ = v/f = (343 m/s)/(72.4 Hz) ≈ 4.738 m
So, the distance of the listener from speaker B is ...
3.2 m ± (4.738 m)/2 = {0.83 m, 5.57 m} . . . either of these distances
_____
The location could be at additional multiples of 4.738 m, but we think not. The sound intensity drops off with the square of the distance from the speaker, so identical sound waves from the speakers will sound quite different at different distances from the speakers. For best interference, the distances need to be as close to the same as possible. That will be at 3.2 m and 5.57 m.

<em>Comment on the speed of sound</em>
We don't know what speed you are to use for the speed of sound. We have used 343 m/s. Some sources use 340 m/s, which will give a result different by 2 or 3 cm.
<em>ANSWER</em>
<u>An increase in relative humidity</u>

-3 m/s

per min
oh I think 8m/s to 3m/s to 0m/s
idk probably -0.08
Answer:
Where is the text?
Explanation:
If you refer to the short sentence you wrote as text, I believe the answer is probably the word "crashes" because it shows how the momentum was transferred.
