Answer:

$\frac{I}{I_0}=113.68$

Explanation:

P = Acoustic power = 63 µW

r = Distance to the sound source = 210 m

Acoustic power

$P=IA\\\Rightarrow I=\frac{P}{A}\\\Rightarrow I=\frac{63\times 10^{-6}}{4\times \pi \times 210^2}$

Threshold intensity = $I_0=1\times 10^{-12}\ W/m^2$

Ratio

$\frac{I}{I_0}=\frac{\frac{63\times 10^{-6}}{4\times \pi \times 210^2}}{1\times 10^{-12}}\\\Rightarrow \frac{I}{I_0}=113.68$

Ratio of the acoustic intensity produced by the juvenile howler to the reference intensity is 113.68

if the roller coaster is 127 meters tall and has 622,300 J of potential energy how much does it weigh/ what is the mass?

Xelga [282]

Answer:

500 kg

Explanation:

using the formula Potential energy (p.e)=mgh where g= acceleration due to gravity whose value is 9.8

so,pe =mgh

622300=m*9.8*127

m=500kg
