Significant Figures and Uncertainty

Name

How many significant figures in the following numbers?

1) 2.300 2) 3.003 3) 400 4) 4050 5) 3.040 x 1023

Use these numbers for the following operations, and express the solution with the correct number of significant digits:

A = 30.1 B = 20. C = 1450 D = 28.923 E = 2.450 x 103 F = 30

6) AxB 7) AxF 8) A-D 9) CxFxD 10) A+D+F 11) (E-C)xB

Use these numbers with the given uncertainty for the following operations, and calculate the uncertainty of the answer:

A = 34 +- 2 B = 1.2 +- .3 C = 130 +- 20 D = 1453 +- 6 E = 56 +- 1

12) A+D+E 13) E - A 14) AxD 15) CxB 16) D/E 17) E/A
