AI Thread Summary
The discussion focuses on calculating the frequency of a traveling wave on a string with a linear mass density of 3.4 g/m and a wave speed of 32.8 cm/s. The wave equation provided is y=4.4sin[1.1-3.3t] cm, prompting questions about the wave number (k) and angular frequency (ω). Clarification is provided that ω should be taken as 3.3, not -3.3, which resolves the confusion regarding negative frequency values. The relationship between wave speed, frequency, and wavelength is emphasized, guiding the calculation process. Understanding these parameters is crucial for determining the frequency of the wave accurately.

A string has a linear mass density of 3.4 g/m. When a sinusoidal wave is created on the string with a speed of 32.8 cm/s the displacement of the particles on the string at x=13.3 cm varies with time according to the following equation: y=4.4sin[1.1-3.3 t] cm. Find the frequency.

Well, I am stuck on this question and need a kick in the right direction...

v=f*lambda
angular velocity=2*3.14*f=wave#*velocity

I really don't have a clue as to where to begin...

The equation of a traveling wave moving in the positive x direction is:

y = A \sin(kx - \omega t)

where

k is the wave number
\omega is the angular frequency
A is the amplitude.
 
the equation I am given doesn't have an x variable so am I to assume k= 1.1? or w=-3.3? And if w=-3.3 then the frequency would be a negative number? is that possible?
 
You're given x=13.3 cm.

Also, w is not -3.3, but 3.3.
 
oh ok, thanks for the 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...
