AI Thread Summary
Sound behaves differently in various gases and media due to differences in density and elasticity, which affect wave propagation. When inhaling helium, the reduced density causes higher pitch sounds, while other gases can lower pitch due to their unique properties. Sound waves do not travel the same in water as in air, as their speed and wavelength are influenced by the medium's characteristics. The discussion emphasizes the importance of understanding physical terms related to sound behavior in different environments. Overall, the interaction of sound waves with various media is crucial for comprehending their distinct behaviors.

Homework Statement


If light travels forever in space..Why does sound die off in air?

When a person inhales helium, his voice sounds high. There is another gas when you inhale it, your voice sounds low.
How does this effect work..?

Does a music note of frequency 440Hz have the same wavelength in water as it does in air?


2. The attempt at a solution
The waves span out..? No idea.

Magic?

No, because it doesn't travel through the same medium..?

Thanks for answering!

Call the questions a, b and c.
I think you may have the idea of (a), but the word "span" is not very clear to me.
You must play with (b) a bit. How would you say "sounds high" in physics terms?
Good start on (c). Now what is different about the two media that affects the sound waves? Again, looking for a physics term whose value is different in the two media.
 

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 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

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...
