Compared with the potential energy at the surface, which is −62.6 MJ/kg., the extra potential energy is 3.4 MJ/kg, and the total extra energy is 33.0 MJ/kg. The average speed is 7.7 km/s, the net delta-v to reach this orbit is 8.1 km/s (the actual delta-v is typically 1.5–2.0 km/s more for atmospheric drag and gravity drag).
This is similar to what happens in decimal when certain single-digit numbers are added together; if the result equals or exceeds the value of the radix (10), the digit to the left is incremented: 5 + 5 → 0, carry 1 (since 5 + 5 = 10 = 0 + (1 × 10 1) ) 7 + 9 → 6, carry 1 (since 7 + 9 = 16 = 6 + (1 × 10 1) ) This is known as carrying. When ...
If I expect a or b, and have an equal chance of gaining them, my Expectation is worth (a+b)/2. More than a hundred years later, in 1814, Pierre-Simon Laplace published his tract " Théorie analytique des probabilités ", where the concept of expected value was defined explicitly: [ 8 ]
12-tone equal temperament chromatic scale on C, one full octave ascending, notated only with sharps. Play ascending and descending ⓘ. 12 equal temperament (12-ET) [a] is the musical system that divides the octave into 12 parts, all of which are equally tempered (equally spaced) on a logarithmic scale, with a ratio equal to the 12th root of 2 (≈ 1.05946).
A proton can change into a neutron by emitting a positron (beta plus), and a neutron can change into a proton by emitting an electron (beta minus). — Keenan Pepper 03:59, 1 December 2005 (UTC) [ reply ]
The current CO 2-equivalent emission rates averaging 6.6 tonnes per person per year, [8] are well over twice the estimated rate 2.3 tons [9] [10] required to stay within the 2030 Paris Agreement increase of 1.5 °C (2.7 °F) over pre-industrial levels. [11]
The Jewish median age in Jerusalem district and the West Bank are 24.9 and 19.7, respectively, and both account for 16% of the Jewish population, but 24% of 0- to 4-year-olds. The lowest median age in Israel, and one of the lowest in the world, is found in two of the West Bank's biggest Jewish cities: Modi'in Illit (11), Beitar Illit (11) [ 40 ...
