AI Thread Summary
The discussion focuses on determining the appropriate susceptibility of Bismuth to calculate for an experiment. The user is uncertain whether to use molar, mass, or volume susceptibility, as the experiment did not specify. The formula provided involves susceptibility (X) and requires matching its units with the different types of susceptibilities listed. It is noted that volume susceptibility is unitless, which aligns with the experiment's findings. Ultimately, clarity on the units of susceptibility is essential for accurate calculations.

I am trying to find the susceptibility for Bismuth, but I don't know which one I am after. Wikipedia gives molar, mass and volume. In my experiment we where asked to calculate the susceptibility, but not which one so I don't know which one I should compare with.

In the experiment we used the formula

Fz = -(1/2mu0)*XA(B21-B22)

Where Fz is the force in direction z, against gravity
X is the susceptibility
A is the area
B1 is and B2 are magnetic flux at different points,

MaxManus is hoping for the best

What are the units of X that is used in your formula or textbook? If you compare that with the units of the molar-, mass-, volume-based susceptibilities, one of them should have the same units.
 
Thanks. Volume was unit less, the same was the answer in my experiment
 
Sounds good!
 

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...
