A small raft is floating in a small wading-pool. There are twenty heavy concrete blocks on the raft. A small child pushes the blocks off the raft and into the water.
As a result, would the water level:
A. Rise
B. Fall
C. Stay the same
D. Do any of the above depend on how dense the blocks are
================
Assuming the water is deeper than the height of the blocks?
---
The water level would fall, if "heavy concrete" means denser than water.
Floating, they displace their weight of water. submerged, they displace their volume.
---------------
D. Do any of the above depend on how dense the blocks are
If the density of the blocks is less than that of water (--> they float), then the level of the water would increase.
