How Does Removing Pigs Affect the Decibel Level in a Pig Pen?

AI Thread Summary
The noise level in a pig pen with 213 pigs is measured at 78.1 dB. When 77 pigs are removed, the remaining pigs are assumed to maintain their original squeal intensity, prompting a calculation of the new decibel level. Additionally, the discussion compares the intensity of an orchestra at 87 dB to a single violin at 62 dB, highlighting the significant difference in sound intensity. The forum explores how to derive the intensity of sound produced by one pig using the decibel definition. Ultimately, understanding these sound levels can provide insights into the impact of pig removal on overall noise in the pen.

1- The noise level coming from a pig pen with 213 pigs is 78.1 dB. Assuming each of the remaining pigs squeal at their original level after 77 of their companions have been removed, what is the decibel level of the remaining pigs? Units dB

2- The intensity level of an orchestra is 87 dB. A single violin achieves a level of 62 dB. How does the intensity of the sound of the full orchestra compare with that of the violin’s sound? Find the ratio

You know the noise level and the total intensity. How can you, using the information you have, solve what intensity one of the 213 pigs has?

Hint: Use the definition of decibel.
 
Ardahl O`Hanlan wrote a book and remembered listening to Radio Luxembourg for the Pop music . He said the reception was so bad it sounded like they were --- Deep frying a herd of live pigs.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
