일반물리학 1 — Fluids: Problem 52

52 What fraction of the volume of an iceberg (density 917 kg/m3) would be visible if the iceberg floats (a) in the ocean (salt water, density 1024 kg/m3) and (b) in a river (fresh water, density 1000 kg/m3)? (When salt water freezes to form ice, the salt is excluded. So, an iceberg could provide fresh water to a community.)
