AI Thread Summary
The discussion centers on a problem involving a 6V DC voltage source connected to a 5kohm resistor and a 10 nF capacitor in series. The main question is about determining the voltage drop across the resistor. Clarification is needed regarding whether the voltage drop is being asked for immediately after the connection or after some time has passed, as the answers differ significantly. The initial state requires understanding the behavior of the circuit at the moment of connection, while the final state involves the capacitor charging. The conversation emphasizes the importance of distinguishing between these two scenarios for accurate problem-solving.

Your "attempt" is not a valid line of reasoning. Try again, but first:

Does the question indicate whether the initial state (immediately after the connection) or the final state (after "some time" has passed) is wanted? The answers are completely different.

Answer the answers to either state requires no calculation.

it is immediately after the connection
 

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...
