What is the error in a measurement of 20.0 cm if the true value is 19.5 cm? (2023)
Step 1: Identify the measured value, which is 20.0 cm.
Step 2: Identify the true value, which is 19.5 cm.
Step 3: Calculate the difference between the measured value and the true value by subtracting the true value from the measured value: 20.0 cm - 19.5 cm.
Step 4: Find the absolute value of the difference to get the error: |20.0 - 19.5|.
Step 5: The result of the calculation is 0.5 cm, which is the error in the measurement.
