Показать описание
9702/11/O/N/15: our identical rods have a square cross-section. The rods are placed side by side and their total width is measured with vernier calipers, as shown. The measurement is (8.4 ± 0.1)mm and the zero reading on the calipers is (0.0 ± 0.1)mm. What is the width of one rod?

does the no. of figures after decimal places o the real value depends on the no. of decimal figures used in the uncertainity
