AI Thread Summary
Acoustic resonance can be produced in a 32 cm tube with a sound wavelength of 20 cm, as long as the conditions for resonance are met. The key requirement is that a doubly-reflected wave must align closely with the original wave, specifically within 1/4 wavelength. If the tube's ends are open or closed affects the resonance conditions, but this detail was not specified in the discussion. Understanding the relationship between the tube length and the wavelength is crucial for determining resonance. Therefore, further clarification on the tube's end conditions is necessary for a definitive answer.

I need help with a question about acoustic resonance.

Sound of wavelength 20cm is produced at one end of a 32 cm long tube. Is it possible for resonance to be produced?
 
Physics news on Phys.org
The condition for re-sonance is for a doubly-reflected wave
(now traveling the same direction as the original wave)
to be "almost in-step" with that original wave
"close to" an integer number of wavelengths back.

"close to" effectively means closer than 1/4 wavelength,
because 1/2 wavelength excess leads to total cancellation.

Did they say whether the ends of the tube were open or closed?
 

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...
