- American football is played on a 100-yd-long field, excluding the end zones. How long is the field in meters? (Assume that 1 equals 3.281 feet.)If you live in the United States, you probably know your height in feet and inches. In other countries, metric units are commonly used for measuring such quantities. First, find your height in inches. Then determine your height in a. centimetens and b. metersUse scientific notation to express each of the following quantities with only the base units (no prefix multipliers). 129 pm Express your answer to three significant figures. 8.7 ns Express your answer to three significant figures. 12 fs Express your answer to two significant figures. 34 um Express your answer to two significant figures.
- 1. Multiplication or division: keep the same number of significant figures in the product or quotient as is in the least precise factor. Examples: 3.1 * 25.6=79.360000... = 79 6.7/981.0=0.0068297655... = 0.0068 keep only 2 significant digits 2. Powers or roots: keep the same number of significant figures as in the original number. Example: Sqrt(38) 6.164414... keep only 2 significant digits = 6.2 (11.6)² = 134.5600000... = 135 Exercises 3. Addition or subtraction: Round off, to the number of decimal places determined by the number with the least number of places beyond the decimal point. Example: 31.5+24.61 +3.28+1.19 +0.762 +0.003 = 61.345 1. 3.9 * 78.9= = 61.3 (correct result) 2. 32.01 +96.321 +36.98 +0.00023 +28.9= 3. 26.9/98 = 4. 421 0.003 =1. A box has the following dimensions: 24 inches x 15 cm x 500 mm. Calculate the volume of the box in cubic meter(s). Express your answer in 2 significant figures. Show your work below and put the answer in the yellow box. height width lengthCube A is 2 inches on a side. Cube B is 8 inches on a side. Determine the following:1. The volume of each cube.2. How many Cube As can fit in Cube B (in regards to volume)?3. Noticing that B’s side is 4 times larger than A’s, can you see how you can get answer 2 any way other than finding both cube volumes?
- ProcedurePart A: Circles and Ratio of Circumference/Diameter1. Obtain three different sizes of cups, containers, or beakers with circular cross section. Trace around the bottoms to make three large but different-sized circles on a blank sheet of paper. 2. Mark the diameter on each circle by drawing a straight line across the center. Measure each diameter in cm and record the measurements in Table 2.1. Repeat this procedure for each circlefor three times. 3. Measure the circumference of each circle by carefully positioning a string around the object’s base, then mark the place where the string ends meet. Measure the length in cm and record the measurements for each circle in Table 2.1. Repeat the procedure for each circle for three trials. Find the ratio of the circumference of each circle to its diameter. Fill the ratio for each trial in Table 2.1. 4. The ratio of the circumference of a circle to its diameter is known as pi (symbol π), which has a value of about 3.14. Compare your…I. Significant Figures Solve the following problems: A.
