Answer 1

Submersion because there are no calculations and there is only one uncertain number measurement read once instead of multiple times

Answer 2

Step1:

Identify the Approaches

There are three approaches to measure the density of a metal:

direct measurement, indirect measurement, and submersion.

Step2:

Analyze Accuracy of Direct Measurement

Direct measurement involves using a balance to measure the mass and a ruler to measure the volume. This method can be accurate but is subject to human error and the limitations of the measuring instruments.

Step3:

Analyze Accuracy of Indirect Measurement

Indirect measurement involves using a known density of a reference material to estimate the density of the metal. This method introduces more uncertainty due to the reliance on external references and potential errors in measurement.

Step4:

Analyze Accuracy of Submersion

Submersion involves immersing the metal in a liquid with known density and measuring the displaced liquid volume. This method is less prone to human error and reduces uncertainty because it involves a single measurement of volume and does not require multiple readings.

Step5:

Compare Accuracy and Uncertainty
Submersion is the most accurate method because it avoids the need for multiple measurements, reduces human error, and introduces fewer uncertainties compared to direct and indirect measurements.
