WebMar 2, 2016 · 1 By the equation V = π r 2 h it would suffice for one to measure both the radius and the height to measure the uncertainty in V. Now suppose the absolute uncertainty in measuring the radius is δ r and the absolute uncertain in measuring the height is δ h , then what will be the absolute uncertainty of volume δ V. WebJan 15, 2024 · By this logic, a measuring cylinder with $\pu{0.5 mL}$ graduations has an uncertainty of $\pu{\pm 0.25 mL}$. Because the measurement should also be reported to the same number of decimal places as the uncertainty, however, this suggests that any measurements with this measuring cylinder should be reported to two decimal places …
WebDefinition: Uncertainty and Resolution. The resolution of a measuring device is the “fineness” to which the instrument can be read. An instrument that can measure a quantity more finely is said to have higher resolution.. The uncertainty of a measurement is the interval over which the “true” value of a measured quantity is likely to fall. It is equal to … Web1. The uncertainty of different equipment is varied. This causes even something with a set weight like a 20g weight to weight something different. 2. The 10mL graduated cylinder has a smaller uncertainty due to the small increment. The 100mL has an increment of 5mL so it's harder to see the exact measurement.
