Solving Homework Equations: The Attached Voltage Across Capacitor

AI Thread Summary
The discussion focuses on solving homework equations related to the voltage across a capacitor over time. The user rearranged the voltage equation for resistance and substituted known values for the first part of the problem. For the second part, they applied the power equation using the previously calculated resistance and a voltage of 500V. A response confirms that the capacitor does not need to be considered for the second part of the question. Overall, the user seeks clarification on their approach and the relevance of the capacitor in their calculations.

Homework Equations



The one given in the hint (as attached) for voltage across capacitor wrt time.
P=V^2/R

The Attempt at a Solution



I just wanted to know whether I've gone about this question in the right way. For the first part I simply rearranged the voltage equation for the resistance R and substituted the known values.

For the second part, I simply used the power equation above and substituted in the previously calculated resistance and 500v for the voltage. I'm not sure if that's right though, and I'm not sure how to account for the capacitor, or if it's required even. Any help?

Thanks!

That is correct. The capacitor does not matter in the second part.
 
Thanks for the reply!
 

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...
