The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
V̇O 2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. [1] [2] The name is derived from three abbreviations: "V̇" for volume (the dot over the V indicates "per unit of time" in Newton's notation), "O 2" for oxygen, and "max" for maximum and usually normalized per kilogram of ...
In 2018 NASA announced the Parker Solar Probe was the fastest ever, with a speed of 153,454 miles per hour (68,600 m/s). [28] The difference between the approximations for the Parker Solar Probe in 2018 is 3 v 2 4 c 2 ≈ 3.9 × 10 − 8 {\displaystyle {\tfrac {3v^{2}}{4c^{2}}}\approx 3.9\times 10^{-8}} , which accounts for an energy correction ...
(1) Conversion 1 gallon of gasoline=33.7 kW·h. (2) The 2014 i3 REx is classified by EPA as a series plug-in hybrid, while for CARB is a range-extended battery-electric vehicle (BEVx). The i3 REx is the most fuel economic EPA-certified current year vehicle with a gasoline engine with a combined gasoline/electricity rating of 88 mpg-e, but its ...
The Lower Peninsula, shaped like a mitten, is 277 miles (446 km) long from north to south and 195 miles (314 km) from east to west and occupies more than two-thirds of the state's land area. The surface of the peninsula is generally level, broken by conical hills and glacial moraines usually not more than a few hundred feet tall.
High-altitude balloons or stratostats are usually uncrewed balloons typically filled with helium or hydrogen and released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level. In 2013, a balloon named BS 13-08 reached a record altitude of 53.7 km (33.4 mi; 176,000 ft). [1]
By 1928, Barringer had sunk the majority of his fortune into the crater – $500,000, or roughly $7 million in 2017 dollars." [ 33 ] Barringer spent 27 years trying to locate the nonexistent deposit of meteoric iron , and drilled to a depth of 1,375 ft (419 m), but no significant deposit was ever found.
The refractive index of liquid water (1.333 at 20 °C (68 °F)) is much higher than that of air (1.0), similar to those of alkanes and ethanol, but lower than those of glycerol (1.473), benzene (1.501), carbon disulfide (1.627), and common types of glass (1.4 to 1.6). The refraction index of ice (1.31) is lower than that of liquid water.
