You measure a quantity, say A, and it has a 1% uncertainty.
If you calculate the value of 100A, its uncertainty will be



a. 100%

b. 10%

c. 1%

d. Need more information since it depends on what A is.

  • physics -

    c. The relative uncertaibty remains the same when you multiply by a constant.

  • physics -

    its just a simple ratio problem

    solution:

    100A X
    A 0.01

    THEN THE EQUATION WILL BE

    100A/A=X/0.01
