) A schoolgirl steps on a scale which reads 32.7 kilograms. We know that the scale has measurement uncertainty of 2%, meaning a fractional uncertainty in the form of (1+%00). Ve know that the girl stepped on the scale with her schoolbag and overcoat. By different neasurement devices it turned out that the schoolbag is 1.2 + 0.1 kilograms and her overcoat veighs 2.74 0.09 kilograms. What is the weight of the schoolgirl without her schoolbag nd the overcoat. Express your answer using absolute uncertainty. Please show your omputations step by step.

() A schoolgirl steps on a scale which reads 32.7 kilograms. We know that the scale has
a measurement uncertainty of 2%, meaning a fractional uncertainty in the form of (1+%00):
We know that the girl stepped on the scale with her schoolbag and overcoat. By different
measurement devices it turned out that the schoolbag is 1.2 ± 0.1 kilograms and her overcoat
weighs 2.74 + 0.09 kilograms. What is the weight of the schoolgirl without her schoolbag
and the overcoat. Express your answer using absolute uncertainty. Please show your
computations step by step.
