Question

what is the intensity of 1.5 w sound at a distance of 5.2 m?

Answer 1

Answer:

4.4×10 ^-3 W/M^2

Answer 2

Given that,

Power of sound, P = 1.5 W

Distance, r = 5.2 m

To find,

It is required to find the intensity of 1.5 W sound at a distance of 5.2 m.

Solution,

The intensity at a distance of r is given by :

$I=\dfrac{P}{4\pi r^2}\\\\I=\dfrac{1.5}{4\pi (5.2)^2}\\\\I=0.00441\ W/m^2\\\\I=4.41\times 10^{-3}\ W/m^2$

So, the intensity at a distance of 5.2 m is $4.41\times 10^{-3}\ W/m^2$.
