Water is in the big beaker in the figure on the left. Scale 1 reads 87 Newtons, scale 2 reads 544 newtons, and scale 3 reads 0 newtons. The hanging block has a density of 15 x 10^3 kg/m^3.

What does scale 1 read after the block is fully lowered into the beaker of water?

What is the new reading on scale 2?

The experiment is repeated with the valve opened. What is the new reading on scale 3?

With the valve opened, what is the new reading on scale 2?
