II. An ordinary ruler has a limited resolution and a higher smaller scale division (SSD) which produces less accurate measurements compared to that of the Vernier caliper and micrometer caliper in measuring the dimensions of small objects. II. Measurements using the Vernier caliper and micrometer caliper are more accurate compared to an ordinary ruler because the calipers acquire auxiliary scales (VSR and CSR), which can be used to properily estimate the dimensions of smaller objects.

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 =
I have an homework where I was asked to get a generic 12 in/30 cm ruler and then answer the question in bold: Look at the smallest division and record what the uncertainty ▲x is of your tool. I am not sure how to ansswer this. Note: the previous question asked me to choose a unit of measurement on our tool which is the ruler and I choose inches (I hope that is a unit of measurement).

Run up a flight of stairs as fast as you can, measure the time it takes and the height of one stair, and count the number of stairs. If you don't know your weight, measure that too. These measurements need not have three significant digits, but the calculated values do. Recall that 1 inch is about 2.54 centimeters, and 2.2 pounds is the weight of about 1 kg of mass.weight = 148.5 poundstime = 1.66 sheight of one stair = 18.5 cm, number of stairs = 12a. What is your power while running up stairs? Include units in your answer. b. The human body has an efficiency of about 28 percent.
