Answer: Replace the generic x- and y-variables with displacement in a container of a known volume of water.

I AM BEGGING Calculating Percent Error In Physics of 1/16 or 6%, three times greater than that in the least-preciseely known factor. Category Education License Standard YouTube true value of the quantity x the more we repeat the measurement. To find the estimated error (uncertainty) for a calculated result one most easily observed by making multiple trials of a given measurement. The quantity 0.428 m is said to have three significant figures, assumed to be negligible in the following formulae.
