Each cell needs around 1 cm 3 of air per minute at a 10 mA discharge rate. These cells are commonly used in hearing aids. A sealing tab keeps air out of the cell in storage; a few weeks after breaking the seal the electrolyte will dry out and the battery becomes unusable, regardless of use. Nominal voltage on discharge is 1.2 V.
1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.
120 μm – the geometric mean of the Planck length and the diameter of the observable universe: √ 8.8 × 10 26 m × 1.6 × 10 −35 m; 120 μm – diameter of a human ovum; 170 μm – length of the largest mammalian sperm cell (rat) [102] 170 μm – length of the largest sperm cell in nature, belonging to the Drosophila bifurca fruit fly ...

Finally, at the highest rank all of these are grouped together with all other organisms possessing cell nuclei in the domain Eukarya. The International Code of Zoological Nomenclature defines rank as: "The level, for nomenclatural purposes, of a taxon in a taxonomic hierarchy (e.g. all families are for nomenclatural purposes at the same rank ...
