Name: Part 1: Significant Figures Practice-8pts Directions: Carry out the indicated operations below and report the answer to the correct number of significant figures in the space provided. Answers must be typed on this form. 1. 12.7x9.4= 2. 28.4kgm 0.02680s2 3. 0.261+9.79= 4. sin(arccos(0.80) ) = 123.4 m - 4 5 + 0.72 15 5. 6. 2.150s 2.314ft 7. (2.718-2.70)/2.718= 8. 10101 has sig. figs 9. Write 32084 to 3 sig. figs using scientific notation: Express your answers to the following in scientific notation (use proper format): 10. Add 3.890 x 104 and 9.46 x 102 = 11. Multiply 3.3 x 10-3 and 5901 x 10-2 = 12. Divide (4.821x1087) by (2.74x10300)3 = 13. Calculate the average of the following measurements (don't forget to apply the rules for sig figs): 2.04cm, 2.05cm, 2.05cm, 2.06cm, 2.07cm, 2.04cm. Part 2: Standard Deviation and Uncertainty Practice-3pts Calculate the average, standard deviation, and uncertainty of the measurements in question 13. Report your final answer to the correct number of decimal places and significant figures. Show all work. Remember all sections of this document must be typed!Part 2: Error Propagation Practice-14pts Directions: Use error propagation to calculate the uncertainty and percent uncertainty of the dependent quantity in terms of the measured quantities shown (independent variables). Remember, given A=A(x,y,z,...) where the measured quantities have uncertainties ox,dy, Oz,... then SA = 1 . y = e-my2 y is the measured quantity with uncertainty Sy, m is a constant. 2. P=2L+3W, L & W are measured quantities with uncertainty SL and SW 3. P=2L-3W, L & W are measured quantities with uncertainty SL and SW4. f=1/t, t is a measured quantity with uncertainty St. 5. A=w+x+y+z, w, x, y, and z are measured quantities with uncertainty ow, 8x, Sy, and oz 6. V=LWH, L, W, & H are measured quantities with uncertainty SL, SW, SH M 7. P = T ( M2 -M1 ) - d, M, M1, M2, & d are measured quantities with uncertainty SM, SM1, 8M2, 8d
