Dmitriy789 [7]

Answer:

4

Explanation:

I_0 = Threshold intensity for woman

I = Intensity of sound for man

\beta = Intensity level of sound = 6 dB

Intensity level of sound is given by

\beta=10log\dfrac{I}{I_0}\\\Rightarrow 6=10log\dfrac{I}{I_0}\\\Rightarrow \dfrac{6}{10}=log\dfrac{I}{I_0}\\\Rightarrow 10^{\dfrac{6}{10}}=\dfrac{I}{I_0}\\\Rightarrow \dfrac{I}{I_0}=10^{\dfrac{6}{10}}\\\Rightarrow \dfrac{I}{I_0}=10^{0.6}\\\Rightarrow \dfrac{I}{I_0}=3.98\approx 4

The ratio is 4

meriva

Answer:

m = 17.87 kg

Explanation:

As we know that tank itself has mass given as 13.4 kg

so it is given as

m_1 = 13.4 kg

also the tank contains air in it and the mass of air inside the tank is also given as 4.47 kg

so it is

m_2 = 4.47 kg

so total mass of the tank is the mass of the empty tank and mass of air in the tank

m = m_1 + m_2

m = 13.4 + 4.47

m = 17.87 kg
