1. GN-z11 is the most distant galaxy we have observed, its distance from us is 9.8 Giga parsecs (Giga = 109). The parsec (symbol: pc) is a unit of
length used to measure large distances to astronomical objects outside
the Solar System.
If 1 pc = 3.26 light years (ly), and 1 ly = 9.45x1015 m.
a) How far is GN-z11 in ly?

The magnets would be | n s | and | s n|

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
