Astronomers have used the National Science Foundation's Very Long Baseline Array radio telescope to make the first - ever time - lapse movie showing details of
gas motions around a star other than our Sun.
But not only the spatial distributions of titanium and iron resemble those in Cas A. Also the total amounts of these elements, their expansion velocities, and the velocity of the neutron star are in amazing agreement with those of Cas A. «This ability to reproduce basic properties of the observations impressively confirms that Cas A may be the remnant of a neutrino - driven supernova with its violent
gas motions around the nascent neutron star,» concludes H. - Thomas Janka.
Not exact matches
By monitoring the
motion of the nanoparticle over time, the scientists determined the rate at which the nanoparticle hops between the wells for a wide range of frictions, which can be accurately tuned by adjusting the pressure of the
gas around the nanoparticle.
Questions
around the «failed» Apollo 13 mission that cover topics ranging from simple harmonic
motion to gravitation to thermal physics and
gas laws.
HERE»S WHAT I DO N'T LIKE: Loud wind noise (anytime I exceed 40 - 45 mph), makes it hard to hear the radio at normal volume; intrusive road noise, which I corrected by swapping out the standard Goodyear tires with Continental tires; lackluster acceleration for a V6 engine, CVT tends to lose momentum when you lift your foot off of the
gas pedal — often jerky when accelerating and decelerating while in
motion and when accelerating from a dead stop; as mentioned by another reviewer, accelerator hesitates before catching when shifting from reverse to drive; bumps in the road are not well absorbed (the 2016 model may have addressed this issue); no power to windows after you shut off the engine; no auto door locks; poor V6 fuel efficiency averaging
around 24 MPGs combined; trunk lid's arms and safety feature makes it heavy and sometimes hard to lift open; Infotainment system does understand most voice commands; and Harmon Kardon speakers are sometimes crackly.
Also, this is ideal
gas «constant rapid
motion» by which it means travelling at great speeds through empty space, it does not mean the vibrational movement of the molecule which is anyway confined by by the other real
gas molecules under gravity
around it.
