1. A student measures the density of a metal and calculates answer to be 8543.2kgm^-1 . The result is accurate to +- 1.1%
Which of the following states answer to an appropriete number of sig figs?
A 8.543x10^3
B 8.5x10^3
C 9x10^3
D 8.54x10^3
2. Relative Uncertainty = Absolute Uncertainty/ Measured Value
3. First i got the abosute uncertainty by: 8543.2x0.0011 to get +-93.9752
in order to compair the initial value and the initial+-absolut uncertainty values in order to compair them and determain to how many sf they are identical.
I got 8637 and 8449 and thus i couldn't get the answer.
Please help
