If the intensity of a loud car horn is 0.005 w/m^2 when you are 2 meters away from the source. calculate the sound intensity level. a. 1.6 w
b. 0.06 w
c. 97 db
d. 223 db
e. 179 db

(c) 97 dB sound intensity level

Explanation:

We have given the intensity of the loud car horn

We know that

Now the sound intensity level is given by , which is nearly equal to 97

So the sound intensity level will be 97 dB

So option (c) will be the correct option

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
