When a magnet moves near a coil of wire it can cause an A. electric current
Use mv=mv, plug in the know 1x9.24=3m. Solve for m, which m is 3.08M
If you’re talking about noble gases, the answer would be A. Since noble gases already have 8 electrons, they don’t tend to form chemical bonds. And elements need just 8 electrons on there shells to be stable.
