What is the wave speed in a brass wire

AI Thread Summary
The wave speed in a brass wire can be calculated using the formula v = √(T/μ), where T is the tension and μ is the mass per unit length. The mass per unit length is determined by multiplying the density of brass (8.60×10^3 kg/m^3) by the cross-sectional area of the wire. The user has already calculated the cross-sectional area but is seeking guidance on the next steps to find the wave speed. Proper application of the formula will yield the wave speed in the brass wire. Understanding these calculations is essential for solving similar physics problems.

Homework Statement


What is the wave speed in a brass wire with a radius of 4.65×10-4 m stretched with a tension of 128 N? The density of brass is 8.60×103 kg/m^3.


Homework Equations



v=square root of T/u


The Attempt at a Solution



I have already found the cross sectional area but am unsure of what to do from there.

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...
