Acertain source of sound waves radiates uniformly in all directions. at a distance of 14 m from the source the intensity level is 67 db. what is the total acoustic power output of the source, in watts? (note: the reference intensity i 0 is 1.0 × 10-12 w/m2.)

Explanation:

It is given that,

At a of 14 m from the source the intensity level is 67 db. We need to find the total acoustic power output of the source. The intensity level is given by :

(reference intensity)

or

Output power is given by :

P = 0.0123 watts

So, the output power of the source is 0.0123 watts. Hence, this is the required solution.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

answer: a. same unit
