AI Thread Summary
To solve for the currents in the circuit with resistances of 2.00, 3.00, 1.00, 4.00, and 10.0 ohms, a clear circuit diagram is necessary. The discussion emphasizes that this question belongs in the homework help forum and highlights the importance of showing working steps and identifying specific areas of difficulty. Participants are cautioned against submitting answers from the internet to avoid academic penalties, as plagiarism detection is increasingly effective. The thread encourages self-learning and problem-solving rather than seeking direct answers. Understanding Kirchhoff's rules is essential for accurately calculating the currents in the given circuit.

Welcome to PF aly1188;

This belong in the homework help forum. Also, it is PF policy to show your working and specifically where you are stuck. We will try to nudge you in the right direction, but you will have to do the leg-work yourself.

A word of warning, if your lecturer/tutor catches you submitting stuff off the internet you can face some pretty severe penalties. And don't be fooled, it is VERY easy to get caught (even the old fuddy-duddies are pretty awake to online plagiarism these days). I myself issued 45 separate warnings to my students last year.

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...
