Answer:
Explanation:
1. Density from mass and volume

2. Volume from density and mass

3. Mass from density and volume

4. Density by displacement
Volume of water + object = 24.6 mL
Volume of water =<u> 12.8 mL</u>
Volume of object = 11.8 mL

Your drawing showing water displacement using a graduated cylinder should resemble the figure below.

Answer:
A. While inconsistent, his average of 1.0 kg made his results quite
accurate
Explanation:
Accuracy is how close the value you gain from test or observation compared with the real value. In this test, all tests relatively close to 1kg and the average of the test is 1kg so this tool can be considered quite accurate.
The precision determines how close the value of multiple repetitions of the test. In this case, the value varies from 0.8kg to 1.2kg. The highest value is about 50% higher than the lowest value, so the range is pretty far and the test can be considered not precise.
Answer:
there are no mutiple choices
