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%

• 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
