Answer:

The sound level produced by a chorus of 36 singers will be 86.96 dB.

Explanation:

Let I, the intensity of a sound produced by a singer, therefore, the intensity of the sound produced by 36 singers is equal to 36I. Therefore, the intensity is:

x = 10log(36I/Io)

x = 10log(36) + 10log(I/Io)

The second term in the equation is the sound intensity produced by a single singer. We calculate that the sound intensity of 36:

x = 10log(36) + 71.4 = 86.96 dB

Answer: The sound level of the singers is

86.96dB

Explanation:

sound wave can be described by the intensity of sound, which is measured in decibels. The actual intensity, in watts per square meter, varies over a very wide range, so the logarithmic scale is more convenient in intensity characterization. The intensity in decibels is given by 10log10 (I/Io)

Where Io= 10^-12W/m^2 is called the threshold of hearing.

If the intensity of sound produced by 1 singer is I the intensity of sound of 36 singers will be 36I

X = 10log10 (36I/ Io)

Transforming, we have,

X = 10log10 36 + 10log10(I/Io)

X = 10log10 36 + 71.4 fb

X = 15.56 + 71.4 fb

X = 86.96dB

In what fundamental way did the work of Galileo differ from his predecessors who had thought about the sky?
kompoz [17]

Answer: The correct answer is:

Galileo used instruments and experiments to show him what nature was doing, instead of relying on pure logic

Explanation:

Galileo can be considered as one of the precursors of experimentation and the scientific method. A method that doesn't rely on "common sense" and rationalization and logic, but instead is fuelled by a disposition of skepticism and rather makes claims about reality based on experimentation and empirical data shows.

Galileo differed from his predecessors because he actually used and developed instruments and method to reliable measure and observe what nature was doing, instead of relying on pure logic.
