How Is Tension Calculated in a String with Waves?

AI Thread Summary
The linear density of the string is 5.520×10-3 kg/m, and the transverse wave is described by the equation y=(0.033 m)sin(2.50 m-1x +125.7 s-1 * t). The wave speed has been calculated as 50.38 m/s using the formula v = ω/k, where ω is the angular frequency (125.7 s-1) and k is the wave number (2.5 m-1). To calculate the tension in the string, the formula T = μv² can be used, where T is tension, μ is linear density, and v is wave speed. The discussion emphasizes the need for assistance in calculating the tension after determining the wave speed.

The linear density of a string is 5.520×10-3 kg/m. A transverse wave on the string is described by the equation

y=(0.033 m)sin(2.50 m-1x +125.7 s-1 * t).

1.) What is the wave speed?




2.) What is the tension in the string?


I've already calculated the wave speed but I don't know how to do the tension in string!

HELP PLS!

wave speed (v) = w/k

y= Asin(kx-wt)

w = 125.7
k=2.5

v = 125.7/2.5 = 50.38 m/s (wave speed)But i do not know how to calculate the tension! HELP PLEASEE!
 
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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
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...
