AI Thread Summary
The discussion focuses on the refraction of sound when transitioning from air to water, highlighting that the principles of refraction and reflection apply similarly to both sound and light. The speed of sound is noted as 340 m/s in air and 1510 m/s in water. The problem presented involves calculating the angle of refraction for a sound wave entering water at a 12° angle of incidence. Participants initially expressed confusion about the appropriate value for 'c' in the context of sound. Ultimately, they resolved their uncertainty and found the solution.

Homework Statement


the laws of refraction and reflection are the same for sound as for light. the speed of sound is 340 m/s in air and 1510 m/s in water. if a sound wave traveling in air approaches a plane water surface at an angle of incidence 12°, what is the angle of refraction?

Homework Equations



n=c/v snells law of refraction: n1(sinθ1)=n2(sinθ2)

The Attempt at a Solution


we attempted to use n=c/v but we weren't sure what the c value should be when the equation is used for sound as opposed to light. a push in the right direction?

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...
