A typical high-performance CD-4 system would include a turntable with a CD-4 compatible phono cartridge, a CD-4 demodulator, a four-channel amplifier (or receiver), and four identical full-range loudspeakers. [5] CD-4 encoded records were also compatible with conventional two-channel stereo playback systems. In stereo mode all four channels of ...
Gliese 436 b / ˈ ɡ l iː z ə / (sometimes called GJ 436 b, [7] formally named Awohali [2]) is a Neptune-sized exoplanet orbiting the red dwarf Gliese 436. [1] It was the first hot Neptune discovered with certainty (in 2007) and was among the smallest-known transiting planets in mass and radius, until the much smaller Kepler exoplanet discoveries began circa 2010.
Extraterrestrial atmosphere. Major features of the Solar System (not to scale) Graphs of escape velocity against surface temperature of some Solar System objects showing which gases are retained. The objects are drawn to scale, and their data points are at the black dots in the middle. The study of extraterrestrial atmospheres is an active ...
USS Norton Sound (AV-11/AVM-1) was originally built as a Currituck-class seaplane tender by Los Angeles Shipbuilding and Dry Dock Company, San Pedro, California. She was named for Norton Sound , a large inlet in West Alaska , between the Seward Peninsula and the mouths of the Yukon , north-east of the Bering Sea .
The answer could explain why Neptune’s core is hot. Scientists have finally discovered how sheets of diamond rain form on the ice giants, Neptune and Uranus. The answer could explain why Neptune ...
An example of a material in which absorption can observed: sound absorbing foam, also known as acoustic foam. In acoustics, absorption refers to the process by which a material, structure, or object takes in sound energy when sound waves are encountered, as opposed to reflecting the energy. Part of the absorbed energy is transformed into heat ...
Follow these steps: Turn on the pulse oximeter and place it on your fingertip, ideally the middle or index finger. Sit still and avoid moving while the device reads your oxygen levels and heart ...
Neptune is the eighth and farthest known planet from the Sun. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth and slightly more massive, but denser and smaller, than fellow ice giant Uranus.
