What is the percent uncertainty in the measurement 3.26 plus or minus 0.25 m?

To calculate the percent uncertainty, divide the absolute uncertainty by the measured value and multiply by 100. Here, the absolute uncertainty is 0.25 m, and the measured value is 3.26 m. The calculation is (0.25 m / 3.26 m) × 100, which equals approximately 7.67%. Thus, the percent uncertainty in the measurement is about 7.67%.
