What bound of error would you pose for each of the following cases? (consider rules of significant figures) The width of a board is 8.6 cm, measured with a millimeter ruler. The width of a road is 523.4 cm, measured with a small millimeter ruler of 30 cm. The thickness of a paper when measuring the thickness of 100 papers with a millimeter ruler and dividing by 100 results in 0.40 mm The thickness of a paper measured with a micrometric screw that reads to the hundredths of a millimeter is 0.42 mm. The time of 10 oscillations measured manually with a stopwatch that appreciates up to 0.2 s is 12.4 s.
Hello good afternoon, could you help me with the subsections of this problem?
It has been complicated for me but I have been told that it is simple.
Beforehand thank you very much.
