Q Search for 20 minutes. Then return, put it down, and weigh yourself immediately three times. Since reporting your weight is a little too personal, I want you to tell me the variation between each reading (called a first derivative measurement). You should see the first weight is somewhat higher than the rest; often as much as 2-3 pounds. What do you th this tells you about your scale's quality? All other data is provided in the lab procedure Questions So, go ahead and answer them, then. a For measuring the block, (part 1) measure something and tell me what it is. Today, definitions. Here are your lab questions: 1. Define significant figure 2. Define accuracy 3. Define precision 4. How many significant figures are present in the measurement 0.053402 mm? How many are in 0.053400? Calculate the following: For three replicate (repeated) measurements, your values are as follows: 3.510 g; 3.565 g; 3.593 Answer the following questions: a. What is the average? b. the percentage error (the…
