AI Thread Summary
The discussion revolves around a physics problem involving two microphones and a sound source, where the distance between the microphones is 1.5 meters and the speed of sound is 343 m/s. The calculations for the distances L1 and L2 from the sound source to each microphone yield L1 as approximately 1.996 meters and L2 as about 2.4968 meters. However, a critical oversight in the solution is the omission of units for the calculated distances. The importance of specifying units in physics problems is emphasized, as it is essential for clarity and accuracy.

Homework Statement



One microphone is located at the origin, and a second microphone is located on the +y axis. The microphones are separated by a distance of D=1.5 m. A source of sound is located on the +x axis, its distances from microphones 1 and 2 being L1 and L2, respectively. The speed of sound is 343 m/s. The sound reaches microphone 1 first, and then .00146 s later, microphone 2. Find the distances L1 and L2


Homework Equations





The Attempt at a Solution



L1= x
L2= x + (343 * .00146)

1.5^2 + X^2 = (x+ (343*.00146))^2
x= 1.996

L1=1.996
L2=2.4968

The answer almost looks OK. You just forgot one thing...
 
i feel its perfectly ok..
please tell what he forgot
 
Units!

L1 = 1.996 lightyears? meters? yards? GeV-1?
 

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...
