Nodal analysis voltage confusion

AI Thread Summary
The voltage across the R2 resistor is expressed as vT-0 = vT, while the voltage across the R1 resistor is noted as vT-Vs1, leading to confusion about the nodes involved. Clarification is needed on whether the nodes for R2 are the same as those for R1. Additionally, there is uncertainty regarding the voltage source Vs1 and the specific nodes it connects. The diagram provided in the discussion indicates the exact connection points for Vs1. Understanding these node relationships is crucial for accurate circuit analysis.

So the voltage across the R2 resistor is given as vT-0 = vT

But then the voltage across the R1 resistor is given as "vT-Vs1"
I'm not sure which two nodes the voltage across R2 involves. Is it the same as R1?

Also, I am not sure of the voltage source vs1. Across which two points does it apply?

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
