# uncertainty question watch

1. say log(k)= 10 +/- 0.1 (that means 10 plus or minus 0.1)
how do you find the uncertainty of k?

It means the range of values for log(k) falls between 9.9 and 10.1

The range is found from log(k) = 9.9 (lower limit) and, log(k) = 10.1 (upper limit).

what would the percentage error of k be?

Use log(k) = 10 and work out the pecentage value from the upper and lower vaues of k.

It will be stated as k +upper/-lower %

the + and - are different percentages, is that right?

Yes. It's the same as a skewed error bar.
