And we end up with 12.6 meters per second , Firearm muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s) in black powder muskets, to more than 1,200 m/s (3,900 ft/s) in modern rifles with high-velocity cartridges such as the , Summary. What is the radius of Earth in gravitation? Measure the angle of the shadow of your meter stick when the sun is overhead and the shadow is smallest, often known as local noon (when the sun is exactly north-south in the sky at its highest point). As such, they are topographical geocentric distances, Rt, which depends not only on latitude. Now, lets plug in some numbers. In Eratosthenes case, the distance was 787 kilometers, so for him, the following relation applied: where x = the circumference of the Earth in kilometers. The circumference of the world may be the distance measured around it. R The reason for keeping those older values was GPS.

For the WGS84 ellipsoid, that's respectively: Earth's circumference equals the perimeter length. The following is a partial list of models of Earth's surface, ordered from exact to more approximate: In the case of the geoid and ellipsoids, the fixed distance from any point on the model to the specified center is called "a radius of the Earth" or "the radius of the Earth at that point".

The nominal radius serves as a unit of length for astronomy. Rather, elevation above or below sea level is useful. His highly influential work, the Almagest,[26] left no doubt among medieval scholars that Earth is spherical, but they were wrong about its size. [6] It is an idealized surface, and the Earth measurements used to calculate it have an uncertainty of 2m in both the equatorial and polar dimensions. Earth's diameter is simply twice Earth's radius; for example, equatorial diameter (2a) and polar diameter (2b).
