Answer» ong>Given : The area of an object is calculated from experimental DATA to be 24.6623 cm². The absolute ERROR in the area was determined to be ± 0.6 cm². The area should be reported, in cm² as
solution : FIRST understand what is the meaning of absolute error. absolute error is the AMOUNT of error in our measurements. in short, it is the difference between measured value and true value. i.e., absolute error = measured value - true value. here given measured value = 24.6623 cm² absolute error = 0.6 cm² so, true value = (24.6623 + 0.6) = 25.2623 cm² ≈ 25 cm² so the area should be reported as 25 cm². OPTION (1) is correct choice. |
