rue or False: When applying a line of best fit to a data set, you should always set Error bars on a plot are a visual representation of the magnitude of uncertainties for a measured data point. What is the uncertainty associated with the measured power approximately? Enter a numerical answer, such as "9". E.g. For a measurement of 16 +/- 0.05 V , the range of uncertainty is +/- 0.05V.the intercept to zero such that the best fit line passes through the origin (0,0)
