Answer:The equation relating I, r, and k is I =K/r²
Step-by-step explanation:
The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound can be written as
I ∝ 1/r²
Introducing the constant of proportionality, K we have that
I =K x 1/r²
Therefore , the equation relating I, r, and k is I =K/r²
Answer:
(2000÷25) x 10= 800mm
First you have to divide 2000 by 25 to see what the other side is. If you divide it you get 80. Then you have to times it by 10 to convert it
−
3 x = 15 Divide each term in − 3 x = 15 by - 3 . − 3 x − 3 +15 =− 3 Cancel the common factor of − 3 . Cancel the common factor. − 3 x − 3 = 15 − 3 Divide x by 1 . x = 15 − 3 by − 3 . x = − 5
I'll help if you need it.
