Terminal voltage and current flow

AI Thread Summary
The discussion revolves around calculating the current flow and terminal voltage in a circuit involving a battery with a voltage of 19.0 V and a resistance of 0.55 Ω. The user successfully calculated the current to be 4.52 A but is uncertain about how to determine the terminal voltage of the battery. There is confusion regarding the information provided, specifically about the battery voltages. Clarification is sought on how to approach the terminal voltage calculation. Understanding the relationship between voltage, current, and resistance is crucial for solving the problem.

I don't understand the question. It looks like you are given the battery voltages...
 

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...
