Q: A student measures the width of a table as 1.2 m with a possible error of 0.02 m. What is the range of the true width?
Solution:
True width = Measured value ± Absolute error = 1.2 ± 0.02 gives the range 1.18 m to 1.22 m.
Steps: 5
Show Steps
Step 1: Identify the measured value of the table's width, which is 1.2 m.
Step 2: Identify the possible error in the measurement, which is 0.02 m.
Step 3: To find the range of the true width, subtract the possible error from the measured value: 1.2 m - 0.02 m = 1.18 m.
Step 4: Now, add the possible error to the measured value: 1.2 m + 0.02 m = 1.22 m.
Step 5: The range of the true width is from 1.18 m to 1.22 m.
