When compared to a traditional train on a track, what is/are advantages of having a MagLev train? Choose all that apply. 1) Noise is reduced when compared to a tradition train on a track.

2) Travels far distances in a short time. It's really fast.

3) The ground doesn't rumble when the train passes.

4) There are fewer mechanical breakdowns because of the lack of fiction.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

There's nothing  on the list you provided to which that law applies.
