1. Given that the percentage uncertainty in x is 3% and the percentage uncertainty in y is 5%, what is the percentage uncertainty in z = (x/y)^0.5?
Please guide me in this question, thanks! :)
Δz/z x 100% = Percentage uncertainty in z
(X = power of x, Y = power of y)
Δz/z = X(Δx/x) + Y(Δy/y)
Δz/z = 0.5(3/100) + 0.5(5/100)
Δz/z x 100% = 1.5% + 2.5%
Percentage uncertainity in z = 4%
p/s. i dunno wad and how to delete that block of text above
Mod: Deleted that block :)
