Name: Date: CVEN207-Sures2019 In today's laboratory we will learn measurement technigues that will be used in laboratory over the routine calculations. Lastly we will look at how uncertainty relates to measurement, precision and Laboratory # 2 : Measurement and UncertaintyY Introduction semester. We will also examine the use of dimensional analysis and significant figures in performing accuracy. Precision Scientific measurements should be as precise as possible: this means that every measurement will include one uncertain or estimated digit. The number...
How many significant digits are in the length measurement 100.60 centimeters?
PRE-LAB 1. Two metric rulers (shown below) are available to measure the length of the pencil. For each ruler: a. Identify the smallest increment that is marked b. Consider the uncertainty associated with measurements made with that ruler. c. Identify the digit that has to be estimated. d. Record the length of the pencil. e. Identify the number of significant figures in the measurement. Ruler #1 (Top Ruler) Ruler #2 (Bottom Ruler) * os an to Inches inch Smallest increment...
