Answer 1

I would assume that under “speed of electricity” you mean “speed of electric field propagation”.

And important thing here is: *electric field does not push air*. And where would a sonic boom come from, then?

To get it we need something which does push the air to move above speed of sound (a very fast plane, a very hot (and thus very fast-expanding) gas, a volume of gas under very high pressure suddenly depressurized). Nothing like that we have – no sonic boom.
