Heya!!
For calculate velocity, lets applicate formula
<u>Δ Being Δ</u>
d = Distance = 3790 m
t = Time = 249 s
v = Velocity = ?
⇒ Let's replace according the formula and clear "v":
⇒ Resolving
Result:
The velocity is <u>15,22 meters per second.</u>
Good Luck!!
The diagram is missing; however, we know that the intensity of a sound wave is inversely proportional to the square of the distance from the source:
where I is the intensity and r is the distance from the source.
We can assume for instance that the initial distance from the source is r=1 m, so that we put
The intensity at r=3 m will be
Therefore, the sound intensity has decreased by a factor
