Answer:
Answer D
Step-by-step explanation:
The formula is
. We have our r (radius) and h (height), so plugging it all in would give us A = (3.14)(5 + sqrt(12^2)+(5^2). After computing this, you would get answer D, 282.6.
Answer:
So, the time interval between successive compression from the source is 0.002 seconds.
Step-by-step explanation:
Given that,
Frequency of the tone, f = 500 Hz
It is sitting at a distance of 450 m from the source of sound, d = 450 m
Let t is the time interval between successive compression from the source. We know that the relation between the frequency and the time period is :

<h3>So, the time interval between successive compression from the source is 0.002 seconds.</h3>
