Question

3. Rotation of Earth Distances​

Answer 1

Answer:

Consider the movement of the earth's surface with respect to the planet's center. The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers.

Answer 2

Answer:

Circumference of the Earth at 40-deg North = 30,600 kilometers. Time to complete one Rotation = 24 hours. Speed of Rotation at 40 North = Distance/Time = 30,600 km / 24 hr = 1280 km/hr. [Note: For the more mathematically inclined, the rotation speed at a given Latitude = cos(Latitude) x 1670 km/hr.]
