1 significant digit but the answer doesn't make sense

[QUOTE="etotheipi, post: 6413040"] I feel it's a bit harsh to deduct points for incorrect significant figures, considering they don't tell you anything about the uncertainties in those measurements. If you take it at face value, then I guess you just have to assume that ##f_0 = (400 \pm 1) \text{Hz}## and ##v = (20 \pm 1) \mathrm{ms^{-1}}##. What was the error on the value you used for the speed of sound? Propagate those through quickly, and check what the error on ##f## is, and print a suitable number of significant figures. [/QUOTE]
