A sound wave from a siren has an intensity of 111.2 W/m2 at a certain point, and a second sound wave from a nearby ambulance has
Kazeer [188]

Answer:

The intensity level of the sound wave due to the ambulance is 153.5 dB.

Explanation:

The intensity level of the sound wave due to the ambulance can be calculated using the following equation:

\beta = 10log(\frac{I}{I_{0}})

<u>Where</u>:

I: is the intensity of the sound wave from a siren = 111.2 W/m²      

I₀: is the reference intensity = 1.0x10⁻¹² W/m²

\beta = 10log(\frac{111.2 W/m^{2}}{1.0 \cdot 10^{-12} W/m^{2}}) = 140.5 dB

Now, since the second sound wave from a nearby ambulance has an intensity level 13 dB we have:

I_{a} = 13 dB + 140.5 dB = 153.5 dB

Therefore, the intensity level of the sound wave due to the ambulance is 153.5 dB.

I hope it helps you!

20 cubic inches of a gas with an absolute pressure of 5 psi is compressed until its pressure reaches 10 psi. What is the new vol
Alborosie
Initial volume of the gas (V1) = 10 inches^3
Initial pressure (P1) = 5 psi
Final pressure after compression of the gas (P1) = 10 psi
Let us assume the final volume of the gas (V2) = x
According to Boyle's Gas law, the pressure and volume of a gas remains constant under ideal condition. Then
P1V1= P2V2
5 * 10 = 10 * x
50 = 10x
x = 50/10
   = 5 cubic inches
So the volume of the gas after it was compressed was 5 cubic inches. I hope the procedure is clear enough for you to understand.
