2 cards from this section. Quick, good the night before a test.
Calculate the total uncertainty of A = 10.00 ± 0.02 g and B = 5.00 ± 0.01 g when added.
Add the absolute uncertainties.
If two distances are measured as 30.0 ± 0.1 m and 50.0 ± 0.2 m, what is the total distance?
Keep in mind to add the uncertainties.
When adding two measurements, how is total uncertainty determined?
Think about how the uncertainties relate to the measurements.
True or False: Systematic errors can vary in magnitude for repeated measurements.
Consider how errors influence measurement reliability.
A balance shows a weight of 75.0 ± 0.5 g, and you want to mix it with a substance weighing 50.0 ± 0.3 g. After mixing, calculate the total mass and its uncertainty.
Look closely at how you add weights.
You measure a creature at 20.0 ± 0.2 cm and another at 15.0 ± 0.1 cm. Calculate the effective combined length when they are placed end to end.
Concentrate on the addition of both lengths and uncertainties.
