What is the absolute error in a measurement of 50.0 cm if the true value is 48.0 cm? (2022)
  • Step 1: Identify the measured value, which is 50.0 cm.
  • Step 2: Identify the true value, which is 48.0 cm.
  • Step 3: Subtract the true value from the measured value: 50.0 cm - 48.0 cm.
  • Step 4: Calculate the difference: 50.0 cm - 48.0 cm = 2.0 cm.
  • Step 5: Take the absolute value of the difference. Since 2.0 cm is already positive, the absolute error is 2.0 cm.
