Ice has a density of 920 kg/m³ and sea water 1025 kg/m³.
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
Ice has a density of and sea water . What part of a floating iceberg is under the sea? What part of a floating log of density is under the sea?
Need a reminder? The key ideaShow
Archimedes: the buoyant force equals the weight of liquid pushed aside, . An object floats if it is less dense than the liquid, with a part under the surface.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Iceberg. , so .
Step 2. Log. , so .
Answer: of the iceberg, of the log.
