Lab 1 #6
See Error, Uncertainty and Graphs: Propagation of Errors, addition or subtraction . For the first part note: the time measured is the difference of 2 time measurements T1 at the begin and T2 at the end. Which expression in Propagation of Errors gives the error of this difference when you use the errors for T1 and T2 given ? For the second part see "Absolute Error" (1.1).

I don't know where to start with this question. Is .2s dx?
Disregard. I read the info as start + end error = .2 instead of start error = end error = .2!
I'm having trouble determining both errors. Any help would be appreciated.
plz.. helpp!!
cant seem to figure out part a can anyone help? setting starterror+enderror=.3 solving for start error then plugging my start error into the eq 1.6 for error A. once i solve this eq i subtract to find the difference but my answer is always wrong. what am i doing wrong?
need help too. cant figure out what the problem is asking for or how to do it. I only figured out the time for each turn (but not it's error either)
ok so for this problem my numbers are .3 20.8 and 20 turns
part a i did .3squared+.3squared then i found the square root of this number and that was my answer for part b i did
20.8/20 this gave the first part
the second part is your part A answer/the number of spins in my case 20.
hope this helps
