[22] For both Aristotle and Eratosthenes, uncertainty in the accuracy of their estimates is due to modern uncertainty over which stadion length they meant. If no sub- or superscripts appear on this page - for example, if the "Mass" is given in units of "(1024 kg)" - you may want to check the notes on the sub- and superscripts. The structure of the Earths upper mantle can be derived from seismic waves. In the modern age, satellites often provide the most accurate and current information through global imaging. It is 6356. Where K is the Gaussian curvature, Physics, 22.06.2022 11:40, yfnal3x. The Earth's mean radius of curvature at latitude is:[12]:97. The planet bulges at the equator as a result of its rotation. A few definitions yield values outside the range between polar radius and equatorial radius because they include local or geoidal topography or because they depend on abstract geometrical considerations. Therefore, if the earth is taken to be a two dimensional object, its perimeter would be equal to the. det Of course, no one is claiming the size of Earth has actually changed. Thus the curvature found this way is smaller than the curvature of a circle of constant latitude, except at the equator. are tangents to the surface. Now, lets plug in some numbers. Putting in the numbers, you have Dividing both sides by m1 gives you the acceleration due to gravity: Newton's law of gravitation gives you the acceleration due to gravity near the surface of the Earth: 9.8 meters/second 2. The value of the radius is completely dependent upon the latitude in the case of an ellipsoid model, and nearly so on the geoid. How do you find the radius in circular motion? Regardless of the model, any radius falls between the polar minimum of about 6,357km and the equatorial maximum of about 6,378km (3,950 to 3,963mi). F It is the smallest planet in the Solar System, with an equatorial radius of 2,439.7 km. 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. which differs from the exact result by less than 1m (4105in); the mean of the two axes. When considering the Earth's real surface, on the other hand, it is uncommon to refer to a "radius", since there is generally no practical need. He noticed that the difference in the angle of a shadow in his location at Syene, which is present-day Aswan in Egypt, and that of a shadow in Alexandria was about 7.2 degrees. Since Earth is roughly spherical, calculating its volume is relatively simple. In general, this points to an important conclusion about nature itself. 2 The geoid height variation is under 110m (360ft) on Earth. What is the radius of the Moon around the Earth?
