Part 1: A magnetic levitation or maglev train rides rails without touching them. Explain how this works using your data. Include the appropriate magnet drawing in your answer. Part 2: Two objects are near a bar magnet. One is about 1 cm away, while the other is 6 cm away. Compare and contrast the magnetic force that affects each object. Use your data to answer the question

Ireally just need to get finished with precal! i’m really sorry i have to do this! hope this !

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.
