Jolie builds a model of a maglev train. She uses disc magnets to levitate the train. A disc magnet has its north and south poles on its faces, as shown. A round, 3 dimensional object labeled N on top and S on bottom.
What is the best way to arrange the magnets on the train and on the track so that the model train levitates?

flat, so that the north pole of each magnet on the train points up and the north pole of each magnet on the track points up
flat, so that the north pole of the magnets on the train point up and the north poles of the magnets on the track point down
on edge, so that the north poles of the magnets on the train point to the front and the north poles of the magnets on the track point toward the rear
on edge, so that the north pole of each magnet on the train and on the track point toward the rear of the train

Working on this program in python 3.7: a year in the modern gregorian calendar consists of 365 days. in reality, the earth takes longer to rotate around the sun. to account for the difference in time, every 4 years, a leap year takes place. a leap year is when a year has 366 days: an extra day, february 29th. the requirements for a given year to be a leap year are: 1) the year must be divisible by 42) if the year is a century year (1700, 1800, the year must be evenly divisible by 400some example leap years are 1600, 1712, and 2016.write a program that takes in a year and determines whether that year is a leap year.ex: if the input is 1712, the output is: 1712 is a leap year. ex: if the input is 1913, the output is: 1913 is not a leap year. your program must define and call the function isleapyear(useryear). the function should return true if the input year is a leap year and false otherwise.

Create a program that will take in a single x and y coordinate as the origin. after the input is provided, the output should be all of the coordinates (all 26 coordinates read from the “coordinates.json” file), in order of closest-to-farthest from the origin.
