WebSep 20, 2024 · The uncertainty of a measuring instrument is estimated as plus or minus (±) half the smallest scale division. For a thermometer with a mark at every 1.0°C, the uncertainty is ± 0.5°C. This means that if a student reads a value from this thermometer as 24.0°C, they could give the result as 24.0°C ± 0.5°C. WebJan 8, 1998 · the average is 23.5cm/s, and the average deviation is 0.7cm/s, then the number can be expressed as (23.5 ± 0.7) cm/sec. ... Step 1: calculate the uncertainty in cos θ by comparing cos (34.6) to cos(34.6 + .2). The uncertainty in cos θ is taken as the difference between these numbers. Thus cos
WebAug 27, 2010 · Solution. Let x, y and z be the box’s length, width and height, respectively, and the uncertainties be Δ x, Δ y, Δ z. Since V = x·y·z, we can use Eqn. 1 to determine the uncertainty in the volume ( Δ V), which results in Eqn. 4. We know that , and , and can then make these substitutions in Eqn. 4 to give Eqn. 5.
