In heartwood it occurs only in the first and last forms. Wood that is thoroughly air-dried retains 816% of the water in the cell walls, and none, or practically none, in the other forms. Even oven-dried wood retains a small percentage of moisture, but for all except chemical purposes, may be considered absolutely dry.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does wood retain in its cell walls despite being air-dried?
Ah, so.. water

The main mineral resource known on the continent is coal. It was first recorded near the Beardmore Glacier by Frank Wild on the Nimrod Expedition, and now low-grade coal is known across many parts of the Transantarctic Mountains. The Prince Charles Mountains contain significant deposits of iron ore. The most valuable resources of Antarctica lie offshore, namely the oil and natural gas fields found in the Ross Sea in 1973. Exploitation of all mineral resources is banned until 2048 by the Protocol on Environmental Protection to the Antarctic Treaty.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the rarest mineral resource on the continent?
Ah, so.. unanswerable

The Bohr magneton and the nuclear magneton are units which are used to describe the magnetic properties of the electron and atomic nuclei respectively. The Bohr magneton is the magnetic moment which would be expected for an electron if it behaved as a spinning charge according to classical electrodynamics. It is defined in terms of the reduced Planck constant, the elementary charge and the electron mass, all of which depend on the Planck constant: the final dependence on h1/2 (r2 > 0.995) can be found by expanding the variables.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What three terms define the Bohr nucleus value?
Ah, so..
unanswerable
