AI Thread Summary
To calculate percent disagreement, the correct formula involves finding the relative error between the expected value and the measured value. In this case, the calculation should be based on the difference between the expected value (0.541) and the measured value (0.715), divided by the expected value, then multiplied by 100 to convert it to a percentage. The correct percent disagreement is approximately 32.2%. The discussion clarifies the importance of using the correct formula for relative error. The participant successfully resolves their confusion and confirms their understanding of the calculation.

Ok, I'm doing my Physics lab and I was told to give a "percent disagreement" if any.. I know it's a very simple question, but I want to make sure if I understood it right...

So say I get an expected value to be .541 and when I calculated it, the answer is .715... so is the "percent disagreement" to be 32%? (.541 + .715/.541)

Can someone verify if this is correct... thanks in advance :smile:

Eeh?
Whatever have you written here??
You are to compute the relative error!
(finding the percent from that is easy, just shift the decinal point two places in the correct direction)
 
Whoops, I got the correct answer but I meant .541 - .715/.541
and my true value was actually .541
Anyway, I got it, thanks
 

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...
