AI Thread Summary
When the amplitude of a sound wave is quadrupled, the intensity increases by a factor of 16, as intensity is proportional to the square of the amplitude. The discussion highlights confusion regarding the relationship between amplitude and intensity, emphasizing the need for clarity on this concept. Participants suggest looking up the relationship in textbooks for better understanding. The original poster expresses frustration over not finding a direct explanation in their materials. Understanding this relationship is crucial for solving related physics problems effectively.

Stupid Amplitude...HELP!

So I am working on some phys homework and I had a question about this problem:
If the Amplitude of a sound wave is quadrupled, by what factor will the intensity increase?

And I thuoght that the relationship between Intensity and amplitude was that Intensity is proportional to the Square of Amplitude...and i don't know for sure...Can you all help?

This looks very much like a question that was in the k-12 section
and I will give the same answer:

You CAN'T do this if you don't know the relationship between amplitude and intensity- I'll bet that's in your textbook: Look it up!
 
well the whole reason i came here was because i couldn't find a direct relationship in my book about it...I tried figuring different things out but its still not the right answer. So, that's why I am totally lost with this question.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
