Question

how do we indicate uncertainties​

Answer 1

Answer:

Uncertainties are almost always quoted to one significant digit (example: ±0.05 s). If the uncertainty starts with a one, some scientists quote the uncertainty to two significant digits (example: ±0.0012 kg). Always round the experimental measurement or result to the same decimal place as the uncertainty.
