Question
1. State the number in scientific notation and write the number of significant figures in each of the following numbers. Explain your answer. a. 37.60 b. 0.0130 c. 13000 d. 1.2300 2. Perform the indicated operations to the correct number of significant figures using the rules for significant figures a. 37.60 x 1.23- b. 6.7/8.975- e. 3.765+1.2+37.21- Three students make measurements (in m) of the length of a rod using a meter stick. Each student's measurements are tabulated in the table below. Using your calculator in statistic mode calculate the mean L, standard deviation S and uncertainty u of the measurements. 3· SD u Student L Student 1 1.4717 1.4711 1.4722 1.4715 Student 2 1.4753 1.4759 1.4756 14749 Student 3 1.4719 14723 14705 14719 Note that the actual length of the rod is determined by a laser measurement technique to be 1.4715 m (this should be considered the standard value). a) State how one determines the accuracy of a measurement. Apply your idea to the measurements of the three students above and state which student has the most accurate measurement.Explanation / Answer
here,
1)
a. 37.60 = 3.76 * 10^1
no. of significant figures is 3
b. 0.013 = 1.33 * 10^-2
no. of significant figures is 3
c. 13000 = 1.3 * 10^4
no. of significant figures is 2
d. 1.2300 = 1.23 * 10^0
no. of significant figures is 3
