- What, roughly, is the percent uncertainty in the volume of a spherical beach ball of radius r = 0.84 ± 0.04 m?arrow_forwardSo we take a pile of paper, we count the number of sheets, and obtain 226. Then, we measure how tall the pile is with a ruler: 24.0 mm. As discussed in section 1, we could have a long argument about how much exactly should the uncertainty of this measurement be. Let’s settle to ± 0.5 mmarrow_forwardIn each of the three cases, which measured value (mass or volume) limits the precision of the calculated density? Note that the absolute uncertainty in volume cannot be compared directly to that in the mass because the units differ (mL and g), so relative uncertainties must be considered. For volume, relative uncertainty by the rules of significant figures is ±0.01 mL / 20.10 mL = ± 0.0005, a unit-less decimal fraction. Give the relative uncertainty for each mass based on your previous answers to #s 1 & 2.
