it looks like I got too big numbers for the uncertainty
Oh, thank you so much I got 38.98 now for part b). I hope that this is correct.You seem to have crossed over terms, e.g. you have ##\frac{\partial Z}{\partial A}\alpha_B## instead of ##\frac{\partial Z}{\partial A}\alpha_A##.
Looks ok. Notice that the fractional uncertainty in d (1 in 14) is far higher than that in M. This means you can ignore the uncertainty in M and write down immediately that the uncertainty in g is 1 in 7 (doubled because of d^{2}).Oh, thank you so much I got 38.98 now for part b).
