Below are sample questions representative of the exercises included on this worksheet and related 12.3 Measurement, SI Units, and Uncertainty skill assessments:

Problem 1Difficulty: Mastery

A pendulum's total time for 20 complete oscillations is measured as 31.6 s. The count of 20 oscillations is exact. Which period should be reported with correct significant figures?

A1.6 s

B1.5800 s

C0.633 s

D1.58 s

Solution & Explanation:The period is 31.6 s divided by the exact count of 20, giving 1.58 s. The measured time has 3 significant figures, and the counted number does not limit the significant figures.

Problem 2Difficulty: Mastery

The planned visual shows a digital voltmeter specification: uncertainty = ±(0.5% of reading + 0.02 V). If the reading is 4.00 V, what absolute uncertainty should be reported?

A±0.005 V

B±0.02 V

C±0.04 V

D±0.50 V

Solution & Explanation:0.5% of 4.00 V is 0.020 V. Adding the 0.02 V term gives a total absolute uncertainty of about ±0.04 V.

Problem 3Difficulty: Mastery

The planned visual shows a measured length 6.40 cm ± 0.05 cm and a model prediction at 6.48 cm on the same number line. Which interpretation best matches the stated uncertainty?

AThe prediction is inside the interval because 6.48 is close to 6.40.

BThe prediction lies outside the measurement interval, so it is not supported by that interval alone.

CThe prediction changes the unit from centimeters to meters.

DThe uncertainty means every value is equally likely.

Solution & Explanation:The measurement interval is 6.35 cm to 6.45 cm. The prediction 6.48 cm is outside that interval, so it is not supported by the stated interval alone.
