What is the magnitude of the current in this ionic solution?

AI Thread Summary
To calculate the magnitude of current in the ionic solution, the positive ions with a charge of +2e and the negative ions with a charge of -e must be considered. The current is determined by the total charge passing per unit time, which involves multiplying the number of positive ions by their charge and the number of negative ions by their charge. The user initially calculated the current incorrectly by not accounting for the charge of the positive ions properly. The correct approach requires multiplying the positive ion count by 2e to find the total charge contribution. Accurate calculations will yield the correct magnitude of current in the solution.

Homework Statement



In an ionic solution, 3.93×10^15 positive ions with charge +2e pass to the right each second while 9.01×101^5 negative ions with charge -e pass to the left. What is the magnitude of current in the solution?

Homework Equations



I = Ch in Q / Ch in T

The Attempt at a Solution



So I did...
R = 1.6x10^-19 * 3.93x10^15 / 1
R = -1.6x10^-19 * 9.01x10^15 / 1
and then I added them...what am I doing wrong?

You forgot to multiply by two here.
 

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...
