Question

Exercise 11: Santa Claus (that right jolly old elf) lives at the North are spending the holiday break in residence at Lakehead University 89.263893 °W). Assuming that you have been a goo your present (or lump of coal) directly to you by the shortest longitude tools available online to calculate the following at the North Pole. Let's assume that you head University (48.418008 °N, or boy, Santa wants to deliver tortest possible route. Use latitude and Q 11.1: What is Santa's latitude and longitude? Q 11.2: How many kms must Santa and his reindeer fly (one way) ndeer fly (one way) to deliver the gift? Q 11.3: Suppose the combined weight of Santa and y increased the earth's wobble and tilted the planet on its axis to 24 longer or shorter? Weight of Santa and your large gift so big and heavy that it anet on its axis to 24 degrees. Would the winter be Q 11.4: Suppose a golden plover, who are renowned for their the South Pole. What longitudinal line should the birds Why is it shortest? Hint: This would also be the shortest route for a whale are renowned for their migrations, left the North Pole for gitudinal line should the bird follow for the shortest distance to travel?

Answer 1

1. The north pole has geodetic latitude 90° North, as well as the direction of true north. At the North Pole, all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value.

SO Santa's latitude =90N , Longitude = any angle

2. Each degree of latitude is approximately 69 miles (111 kilometers) apart

for shortest distance, Santa must follow 89.263893W longitudinal line

Difference in latitude =(90 -48.418008) = 41.581992 degree

so distance = 41.581992 *111km = 4615.601 km

3. its depend on tilting direction of earth

a) if it tilted such that north hemisphere close to the sun cause smaller winter

b) if the tilted opposite winter will be longer

4. for the shortest distance bird must follow anyone longitudinal line and move opposite direction  of current tilting position of the earth axis

because suppose current tilting is clockwise mean both hemispheres also tilted clockwise if bird move

anticlockwise is reach the southern pole by covering the smallest distance
