GEOG1180 Name Scientific Notation, and Significant Figures Part A - Scientific Notation and Rounding Required Materials . calculator Objective The objective of this lab is to gain some practical experience in the use of scientific notation and the solution of simple arithmetic problems. Question 1 Express the following values in scientific notation. (a) 246 (b ) 55,601.67 (c) -25,847 (d) -0.00246 (e) 0.00048 (f) -1,523,000 Question 2 Express the following values in decimal notation. (a) 2.23 x 106 2.5217 x 105 -5.32 x 104 (a) -5.2 x 106 (e ) 6.72 x 10-5 (f ) 1.37 x 103The following questions get a little trickier. Don't panic. They involve calculations using quantities with SI dimensions. It is usually best to treat such problems in two steps. First, determine what dimensions the answer will have. Second, determine the arithmetic value of the answer. Question 2 How many m are in 1 km 2? Question 3 World class sprinters run the 100 m sprint in just under 10 seconds. Thus average speed for the distance is 10 m per second (100 m/10 s = 10 m/s). What was his average speed in km per hour? Question 4 The equatorial diameter of the earth is 12756.2 km. One AU, the average distance between the Earth and the Sun, is 1.496 x 10" km. On average, how many Earths could fit between the Earth and the Sun ? Question 5 What is the difference between perihelion (1.471x10 Km) and aphelion (1.521x10* Km) as a percentage of the average Sun-Earth distance? Question 6 Electromagnetic radiation, including visible light, travels through the vacuum of space at a velocity of 2.9979 x 10 m s".. Remembering that one AU, the average distance between the Earth and the Sun, is 1.496 x 10 km. How long does it take light from the Sun to reach the Earth?Question 3 Complete the following calculations. Express your answer in scientific notation (with one digit on the left of the decimal, e.g. 9.876) and round the answer to the appropriate number of significant figures. (a) (5.00 x 10*) + (7.20 x 103) ( b ) (3.1456 x 10') x (2.0 x 103) (c) (3.14 x 10') x (2.0 x 105 ) (d) (4.64 x 10') / (1.16 x 108) (e ) (7.28 x 10') / (2.785 x 105) (f) 3,015.9 x 56,978.3 (g) 0.00000513 x 2.15 (b) 28,401 + 57,800.15 (1) (6.00 x 103)2 () (2.32 x 10') x (1.68 x102) + (3.245 x 103) Part B - SI Units Question 1 Complete the following conversions. Use scientific notation to express the answers . (a) 1,609 m km (b) 1,609 m mm (c) 357.2 K .C (d) 36.7 .C K
