Question 3 2.0 cm 16 14 12 10 8 4 2842 2006 + 20 20 18 8.0 cm water Floating disk 2 pts For your next science fair, you construct your own scale that is essentially an open U-shaped tube with different diameters. The round vertical tube on the left has a diameter of 2.0 cm and the round vertical tube has a diameter of 8.0 cm. The system is filled with water. There is a disk on top of the water on the right side that can freely float up and down and also acts as a seal (i.e. the water is kept at the lower surface of the disk). The mass of the disk leads to a height difference in the water level of 2.0 cm without any object placed on top of the disk, as shown in the diagram. What is the maximum additional mass you can put on top of the disk without the water spilling over on the left side? Give your answer in grams to three significant figures.
