Some of the technological applications of superconductivity include: the production of sensitive magnetometers based on SQUIDs fast digital circuits, powerful superconducting electromagnets used in maglev trains, magnetic resonance imaging and Nuclear magnetic resonance machines, magnetic confinement fusion reactors, and the beam-steering and focusing magnets used in particle accelerators low-loss power cables RF and microwave filters fast fault current limiters high sensitivity particle detecto
An antecedent is a thing that comes before something else. You might think rap music has no historical antecedent, but earlier forms of African-American spoken verse go back for centuries. In logic, mathematics, and grammar, the word antecedent (from Latin ante-, before + cedere, to yield) has the meaning the first part of a statement.. More generally, it means something that came before, and perhaps caused, something else..
The relative clause in the example above is who murdered his Latin teacher, and its antecedent is the student which it describes or modifies (i.e. the relative clause tells you more about the student). The clause has its own subject (who), verb (murdered) and direct object (teacher).
