AI Thread Summary
The discussion focuses on the impact of air bubbles or water in mercury during a J-tube experiment. Participants highlight that the presence of air bubbles can affect pressure readings and the accuracy of measurements. Water contamination can alter the density of the mercury, leading to skewed results. The conversation emphasizes the importance of maintaining the purity of the mercury for reliable outcomes. Overall, both air and water can significantly influence the experiment's findings.

Hi sinicky! Welcome to PF! :smile:

Hint: what things does a "J-tube" experiment measure?

Which of those things would be affected by air bubbles? :smile:
 

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...
