Question

If the best estimate value of length of rod is 4.23m .
Find
A) uncertaint
B) measured value.

Answer 1

A) To find the uncertainty in the length of the rod, we need to know the level of precision of the measurement. If we assume the uncertainty to be ±0.01m (meaning the measurement could be as high as 4.24m or as low as 4.22m), then the uncertainty would be 0.01m.

B) The measured value of the length of the rod would be 4.23m.
