Lab Partneris) EXPERIMENT1 Experimental Uncertainty (Error) and Data Analysis TI Laboratory Report 1. Significant Figures (a) Express the numbers listed in Data Table 1 to three significant figures, writing the numbers in the first column in normal notation and the numbers in the second column in powers-of-10 (scientific) notation. DATA TABLE1 Purpose: To practice expressing significant figures. 280 528 x0 0.524 15.08 1444 0.0254 83,909 0.060 82.453 000010 2,700,000,000 (b) A rectangular block of wood is measured to have the dimensions 11.2 cm x 3.4 cm X 4.10 cm. Compute the volume of the block, showing explicitly (by underlining) how doubtful figures are carried through the calculation, and report the final answer with the correct number of significant figures. Calculations (show work) Computed volume (in powers-of-10 notation)

Answer 1

Volume of box = V = 11.2 cm times 3.4 cm times 4.10 cm V = 156.128 cm^3 = 160 cm^33 In scientific notation, we can write it as, 1.60 times 10^2 cm^3
