AI Thread Summary
To determine the wave speed from the equation of best fit, the slope of the graph should be calculated, as it represents the relationship between frequency and wave speed. The equation f=(v/2L)n can be utilized, where f is frequency, v is wave speed, L is the length of the string, and n is the harmonic number. It is important to calculate the slope at multiple points to ensure accuracy and minimize errors. The process may seem straightforward, but careful analysis is essential for a correct solution. This exercise serves as a valuable learning opportunity in understanding wave mechanics.

Homework Statement


From the equation of best fit, determine the wave speed, v, for your string.

Homework Equations


f=(v/2L)n

The Attempt at a Solution


So I am supposed to find the speed of a wave using that graph and data. Do I just take the slope and replace the (f/n) in the equation? I feel like that is too simple.

your graph is perhaps straight line with y=0 at x=0 so write down the equation for the function- calculate slope at least 2-3 places to avoid error and see how you can get the answer -looks simple as it is a learning exercise.
 

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...
