For example, 1 / 4 , 5 / 6 , and −101 / 100 are all irreducible fractions. On the other hand, 2 / 4 is reducible since it is equal in value to 1 / 2 , and the numerator of 1 / 2 is less than the numerator of 2 / 4 . A fraction that is reducible can be reduced by dividing both the numerator ...
where F g is the gravitational force acting between two objects, M E is the mass of the Earth, 5.9736 × 10 24 kg, m s is the mass of the satellite, r is the distance between the centers of their masses, and G is the gravitational constant, (6.674 28 ± 0.000 67) × 10 −11 m 3 kg −1 s −2.

Germanium (32 Ge) has five naturally occurring isotopes, 70 Ge, 72 Ge, 73 Ge, 74 Ge, and 76 Ge. Of these, 76 Ge is very slightly radioactive, decaying by double beta decay with a half-life of 1.78 × 10 21 years [ 4 ] (130 billion times the age of the universe ).
A further form of geosynchronous orbit is the theoretical space elevator. If a mass orbiting above the geostationary belt is tethered to the earth’s surface, and the mass is accelerated to maintain an orbital period equal to one sidereal day, then since the orbit now requires more downward force than is supplied by gravity alone.
The hexagonal (d = 4.29 g/cm 3) form of germanium dioxide is more soluble than the rutile (d = 6.27 g/cm 3) form and dissolves to form germanic acid, H 4 GeO 4, or Ge(OH) 4. [6] GeO 2 is only slightly soluble in acid but dissolves more readily in alkali to give germanates. [6] The germanic acid forms stable complexes with di- and polyfunctional ...
GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.
Global warming between 1.7 °C (3.1 °F) and 2.3 °C (4.1 °F) would likely make this melting inevitable. [6] However, 1.5 °C (2.7 °F) would still cause ice loss equivalent to 1.4 m (4 + 1 ⁄ 2 ft) of sea level rise, [23] and more ice will be lost if the temperatures exceed that level before declining. [6]
