Intensity Sound Sound intensity

AI Thread Summary

To calculate the sound intensity of each singer in a choir of 100 voices producing 100 dB, the formula ΔS=10.log(I/Io) is used. In this context, I represents the intensity of the sound produced by the choir, while Io is the reference intensity level, typically set at 10^-12 W/m². Given that the total sound intensity is 100 dB, the intensity level can be converted to intensity using the formula. The resulting intensity for each singer, assuming equal contribution, is determined to be 80 dB. Understanding the relationship between sound intensity levels and individual contributions is key to solving the problem.

Homework Statement

A choir made up by 100 voices (i.e. 100 singers), during the execution of a song, reaches the sound intensity of 100dB. Assuming that all singers sang with the same intensity, the sound intensity of each singer was...?

Homework Equations

ΔS=10.log(I/Io)

The Attempt at a Solution

The correct answer is 80, but I REALLY have no clue on how to get it!

What is I and what is Io here?

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
