To define extremal length, we need to first introduce several related quantities.
Other related quantities, the scalar products of pairs of four-vectors, are also invariant.
The term "gyromagnetic ratio" is sometimes used as a synonym for a different but closely related quantity, the g-factor.
Mass and weight are different, but related quantities.
To get around this, they typically measure a related quantity.
In many cases, instead of measuring target course many systems measured a related quantity called angle on the bow.
However, in a technical sense, spins are not strictly vectors, and they are instead described as a related quantity: a spinor.
During combat, the actual course of the target was not usually determined but instead the skippers determined a related quantity called "angle on the bow."
Below you can find a list with physical sound field quantities and the related psychoacoustical quantities of corresponding auditory events.
