I can see the fourth graduated cylinder clearly now. The water level with the second object in it is at the 45 mL mark. I'll record this as the volume of water and the second object for the second experiment.
Now, let me calculate the displaced volume for the second object by subtracting the initial volume from the final volume.
Displaced volume = Volume of water and object - Volume of water
Displaced volume = 45 mL - 30 mL = 15 mL
Let me summarize my findings:
For the first experiment (with the rock):
- Volume of water: 30 mL
- Volume of water & rock: 40 mL
- Volume of rock (displaced volume): 10 mL
For the second experiment (with the second object):
- Volume of water: 30 mL
- Volume of water & object: 45 mL
- Volume of object (displaced volume): 15 mL
The solution to the worksheet is complete. The displaced volume of the first object (rock) is 10 mL, and the displaced volume of the second object is 15 mL.
