Answer 1

Question:

Which of the following measurements has the least absolute uncertainty, 218kg or 860kg ?

which of the following has the least absolute uncertainty, 6.942x10⁴cm³ or 8.70x10⁵cm³ ?

which measurement has the least relative uncertainty 7.02x10^-1m or 7x10^0m ?

Answer:

218kg and 860 kg measurements will have the same absolute uncertainty if the device used to make measurements is the same

6.942x10⁴cm³ and 8.70x10⁵cm³  will have the same absolute uncertainty if the device used to make measurements is the same

7x10⁰m will have the least relative uncertainty, as this value is bigger (again, if the device used to make measurements is the same).
