Which statements about error propagation are correct?
Hints
- Check whether the rule uses absolute or relative uncertainties.
- Subtraction behaves exactly like addition here, not oppositely.
Show the answer
- B. Multiplying by a constant k scales the uncertainty by |k|
- C. Uncertainties always add in quadrature for independent variables
Why
Subtraction also adds uncertainties in quadrature; product rules use relative uncertainties.
