A closed thin cubical shell and a closed thin spherical shell have the same volume. Both are filled with water at the same temperature, slightly above that of the surroundings, and are placed in the same atmosphere. At the initial moment:
Options:(select one or more)
Answer:
B, C
Solution:
For equal volume the sphere has the smaller surface area, so the cube radiates more (B). Both hold the same mass of water, so the rate of fall is larger for the cube (C). A and D are false.
