At a distance 30 m from a jet engine, intensity of sound is 10 W/m^2. What is the intensity at a distance 180 m?
AleksandrR [38]

Answer:

I_{2}=0.27 W/m^2

Explanation:

Intensity is given by the expresion:

I_{2}=Io (\frac{r1}{r2} )^{2}

where:

Io = inicial intensity

r1= initial distance

r= final distance

I_{2}=10 W/m^2 (\frac{30m}{180m} )^{2}

I_{2}=0.27 W/m^2

What is the wavelength of a wave whose speed and period are 72.0 m/s and 5.00 s , respectively ?
uranmaximum [27]

Answer:

The distance between the two successive crests of the wave is 360m

Explanation:

Wavelength is defined as the property of wave in which the distance between identical points between two successive waves are calculated

Wavelength is referred to as the <em>distance between two successive crests or troughs</em>

<em>Given that:</em>

speed = 72.0 m/s

time = 5 seconds

Using the formula

C = fλ

Where C = speed, f = freequency and λ = wavelength

F = 1 / time

F = 1/5

F = 0.2Hz

From the fomula C = fλ

make λ the subject of the formula

λ = C / f

λ = 72/0.2

<em>λ = 360m</em>
