AI Thread Summary
A wave pulse travels along a steel wire in 24.0 milliseconds, with the wire's mass being 60.0 grams. The speed of the wave depends on the tension in the wire and its linear mass density, represented by the formula √(T/μ). The discussion highlights the need to understand these factors to calculate the wave speed accurately. The initial uncertainty about tackling the problem is resolved by referencing the appropriate formula. Understanding the relationship between tension and mass density is crucial for determining wave speed in this context.

Problem
The figure shows two masses hanging from a steel wire. The mass of the wire is 60.0 g. A wave pulse travels along the wire from point 1 to point 2 in 24.0 ms.

Attempt
None yet, I don't really know how to tackle this :/

What does the speed of a wave traveling down a wire depend on? Look it up.
 
Ohh ok, so by using \sqrt{\frac{T_{N}}{\mu}}, I can find it :D
Thanks for your help
 

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...
