The mass of the satellite is 840 kg. (Assume the Earth's mass is 5.97 1024 kg and its radius is 6.38 106 m.) NASA launches a satellite into orbit at a height above the surface of the Earth equal to the Earth's mean radius.

WebJust multiply the value in degrees by 111195 - this value is (Earth mean radius)*PI/180 - that is 'mean length of one great circle degree in meters on Earth's surface'. The result obtained using this method is within 1% of the geodesic … WebBy how many newtons does the weight of a 100-kg person change when he goes from sea level to an altitude of 5.0 km if we neglect the earth's rotational effects? (The mean radius of the Earth is 6.38 × 106 m, G = 6.67 × 10-11 N ∙ m2/kg2.) A) -0.60 N irish military war museum

Gravitational constant - Wikipedia

WebThe constant of proportionality, G, is the gravitational constant.Colloquially, the gravitational constant is also called "Big G", distinct from "small g" (g), which is the local gravitational field of Earth (equivalent to the free-fall acceleration).Where is the mass of the Earth and is the radius of the Earth, the two quantities are related by: WebThe mechanical ellipticity of the earth (dynamical flattening, symbol J 2) is determined to high precision by observation of satellite orbit perturbations. Its relationship with the geometric flattening is indirect. The relationship depends on the internal density distribution. ... Authalic mean radius = = 6 371 007.1809 m; Radius of a sphere ... Earth's authalic radius (meaning "equal area") is the radius of a hypothetical perfect sphere that has the same surface area as the reference ellipsoid. The IUGG denotes the authalic radius as R 2. A closed-form solution exists for a spheroid: See more Earth radius (denoted as R🜨 or $${\displaystyle R_{E}}$$) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid, the radius ranges from a … See more Geocentric radius The geocentric radius is the distance from the Earth's center to a point on the spheroid surface at geodetic latitude φ: See more The Earth can be modeled as a sphere in many ways. This section describes the common ways. The various radii derived here use the … See more Earth's diameter is simply twice Earth's radius; for example, equatorial diameter (2a) and polar diameter (2b). For the WGS84 ellipsoid, that's respectively: • 2a = 12,756.2740 km (7,926.3812 mi), • 2b = 12,713.5046 km (7,899.8055 mi). See more Earth's rotation, internal density variations, and external tidal forces cause its shape to deviate systematically from a perfect sphere. Local See more The following radii are derived from the World Geodetic System 1984 (WGS-84) reference ellipsoid. It is an idealized surface, and the Earth measurements used to calculate it have an uncertainty of ±2 m in both the equatorial and polar dimensions. … See more The mathematical expressions above apply over the surface of the ellipsoid. The cases below considers Earth's topography, above or below a reference ellipsoid. As such, they are topographical geocentric distances, Rt, which depends not only on latitude.
