North and South of an electromagnetic solenoid

AI Thread Summary
The discussion focuses on identifying the poles of an electromagnetic solenoid. The Right-Hand Rule (RHR) is referenced to determine the pole orientation. It is confirmed that the left side of the solenoid is the south pole, while the right side is the north pole. Participants seek and provide validation for this understanding. The conclusion affirms the correct pole locations based on the RHR.

Is this correct?or are the poles opposite of what they are meant to be.
I believe it is south on the left a confirmation would be great thank you :)

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'

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...
