Answer

Brief Explanations:

Question 1:

First, convert all units to the same unit (grams). 1 mg = 0.001 g, 1 μg = 0.000001 g, 1 kg = 1000 g. 11.6 mg = 0.0116 g, 1021 μg = 0.001021 g, 0.000006 kg = 0.006 g, 0.31 mg = 0.00031 g. Ranking from largest to smallest: 0.0116 g (11.6 mg), 0.006 g (0.000006 kg), 0.001021 g (1021 μg), 0.00031 g (0.31 mg). So the given ranking is false.

Question 2:

Physics is indeed the study of matter, energy, and their relationships, so this statement is true.

Question 3:

In any measurement, due to limitations of measuring instruments and human - error factors, all measurements are subject to some uncertainty. So this statement is true.

Answer:

Question 1: False Question 2: True Question 3: True
