speed of sound vs. altitude if you put this together, you can get a plot of the speed of sound as a function of altitude. oh sure, it will change with weather and stuff, but still you can get a pretty basic model. here is a plot of the speed of sound at different heights above...
An airplane traveling at supersonic speed is moving at a speed greater than the speed of sound in air at that temperature. Mach 1 means a speed equal to that of sound. Mach 2 means a speed equal to twice that of sound, etc. Musical sounds have three basic characteristics; pitch, ...
Sound travels quickly in air at nearly 340 meters per second but can travel through steel at about 5,200 meters per second. 770 MPH is the speed of sound, or Mach 1. When you go to a rock concert, you may have to cover your ears because the sound is so loud. This loudness is ca...
When it is near but below the speed of sound, its speed can be designated at less than Mach 1, for example, Mach 0. 90. Mach is defined as" the ratio of the velocity of a rocket or a jet to the velocity of sound in the medium being considered. " When a plane passes the sound...
Faster than a speeding bullet:20 years after it last flew, Concorde remains unsurpassed in terms of speed in the world of commercial flight. But what was it like to fly at twice the speed of sound? Click through the gallery to get a taste of the airplane's Mach 2 magic. ...
"There is an equivalent of a Mach 1 — a sound barrier — that exists, in terms of galactic cosmic radiation," Alvin Drew, manager of NASA's Deep Space Habitat Project, said Wednesday (Dec. 19) during a presentation with the agency's Future In-Space Operations working group. ...
The Blackbird holds the air speed record of Mach 3 - three times the speed of sound - but the SR-72 will go twice that speed, at up to 7,350kmh.At Mach 6, it would be three times as fast as Concorde.Able to circumnavigate the globe in six hours at an altitude of about 80,...
Significantly increasing the speed of current jetliners means, inevitably, breaking the sound barrier, which presents a whole set of challenges, not all of them technological. Supersonic flight isn’t exactly new: The Concorde linked both sides of the Atlantic for more than three decades until ...
Answer to: A radar sends out a sound wave of 1.50 MHz and senses it again from a moving car at a 1.40 MHz. What is the speed of the car ?. By...
A recent study by researchers at NASA and Binghamton University, State University of New York, could lead to a drastic decrease in flight times. The study, funded in part by the U.S. Air Force, is one of the first steps toward the creation of planes able to move at hypersonic speeds,...
