Capacitors in parallel and in series

AI Thread Summary
To achieve a capacitance of 35nF with a voltage tolerance of 30V, capacitors must be connected in parallel. A single capacitor with a capacitance of 35nF and a voltage rating of at least 30V is required. Connecting capacitors in parallel allows for increased voltage tolerance while maintaining the same capacitance. The original capacitor's maximum voltage of 10V is insufficient for the 30V requirement. Therefore, using capacitors in parallel is the correct approach to meet both capacitance and voltage specifications.

The problem: A capacitor has the capacitance 35nF, the tolerance is max 10V. You have to put 30V over the capacitor . How many capacitors of same kind do you need if you want to achieve same C(35nF) that tolerate 30V?

I have translated it from swedish to english, sorry if my english isn't so good, I hope you understand the though.

Hypothesis: Has it something to do with the connection, serial or parallel? I think that the charge Q should be the same for the new connection therefore we should use parallel connection. Am I wrong?

Answer: You will need 1 capacitor with a capacitance of 35nF and a tolerance of 30V to achieve the same capacitance and voltage tolerance. The capacitors must be connected in parallel in order to achieve this.
 
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...
