Earth's density varies considerably, between less than 2700 kg/m 3 in the upper crust to as much as 13 000 kg/m 3 in the inner core. [13] The Earth's core accounts for 15% of Earth's volume but more than 30% of the mass, the mantle for 84% of the volume and close to 70% of the mass, while the crust accounts for less than 1% of the mass.

Prior to the 1986–87 season, he gained 13 pounds (5.9 kg), reaching close to 270 pounds (120 kg), to compete against the growing number of 7-footers (2.1 m) in the league. [137] The Lakers advanced to the NBA Finals in each of his final three seasons, starting with a championship over Boston in 1987 . [ 1 ]
In light-water reactors, 1 kg of natural uranium – following a corresponding enrichment and used for power generation– is equivalent to the energy content of nearly 10,000 kg of mineral oil or 14,000 kg of coal. [16] Comparatively, coal, gas, and petroleum are the current primary energy sources in the U.S. [17] but have a much lower energy ...
The value obtained this way is said to be the molar heat capacity at constant volume (or isochoric) and denoted c V,m, c v,m, c v,m, etc. The value of c V,m is always less than the value of c P,m. This difference is particularly notable in gases where values under constant pressure are typically 30% to 66.7% greater than those at constant ...
Mass–energy equivalence states that all objects having mass, or massive objects, have a corresponding intrinsic energy, even when they are stationary.In the rest frame of an object, where by definition it is motionless and so has no momentum, the mass and energy are equal or they differ only by a constant factor, the speed of light squared (c 2).
The body produces approximately 2.3 pounds (1.0 kg) of carbon dioxide per day per person, [72] containing 0.63 pounds (290 g) of carbon. In humans, this carbon dioxide is carried through the venous system and is breathed out through the lungs, resulting in lower concentrations in the arteries .
The more than 1,200 [36] cultivars of watermelon range in weight from less than 1 kilogram (2 + 1 ⁄ 4 pounds) to more than 90 kg (200 lb); the flesh can be red, pink, orange, yellow or white. [37] The 'Carolina Cross' produced the current world record for heaviest watermelon, weighing 159 kg (351 lb). [38]
The maximum take-off weight (MTOW) was set at 220,000 pounds (99,800 kg), [16] which was 10,000 pounds (4,540 kg) more than the 727. [17] The 757's higher thrust-to-weight ratio allowed it to take off from short runways and serve airports in hot and high conditions with higher ambient temperatures and thinner air, offering better takeoff ...
