The B-2's maximum speed is 628 mph while the speed of sound is 768 mph, so ii is subsonic (the B-2 cannot fly faster than sound).
No, X-rays do not travel at the speed of sound. X-rays are a form of electromagnetic radiation that travel at the speed of light, which is much faster than the speed of sound.
Light travels much faster than sound - about a million times faster. When an event happens at a distance, light reaches your eyes almost instantly, allowing you to see it first. Sound, on the other hand, travels much slower, taking some time to reach your ears, which is why you hear the event after seeing it.
A bomb explosion travels faster than the humming of a bee because the explosion produces a shockwave that moves at the speed of sound in the medium (air), which is much faster than the buzzing sound produced by a bee.
Sound is a compression wave that travels via then vibrations of particles. If the particles are closer together then the wave (sound) moves faster. Particles are closer together in a liquid than a gas, therefore sound travels faster through liquids.
In simple terms... light travels much faster than sound. We see the lightning flash first, followed by the sound when it finally reaches us
A lot
The F-22, being an air superiority fighter is naturally much faster. It is reputed to have a top speed in excess of mach2 -about 1450 mph (but you can seldom believe anything they publish, and I would not be surprised if it was faster than this.) -The B-2 is a stealth bomber with a high subsonic speed.
If You are asking about the price of B2 Stealth Bomber, then its about $737 million (1997 cost for each aircraft, $1.01 billion today). And the program cost was about US$44.75 billion (through 2004). Source: Wikipedia
Northrop Grumman B-2 Spirit costs $135.000 an hour in flight and the cost per unit is The cost of each aircraft averaged US$737 million in 1997 dollars ($1.01 billion today). In the related links box below, I posted some information about the stealth bomber.
Much faster in a solid
Electricity is faster than sound. The speed of electricity through a conductor is close to the speed of light, which is much faster than the speed of sound through air.
About a million times faster
No one airplane, no one answer. Single seat light plane? Huge jet airliner? Military bomber, fighter, stealth airplane? Not enough information for a good answer.
Light travels faster (much faster) than sound.
No, X-rays do not travel at the speed of sound. X-rays are a form of electromagnetic radiation that travel at the speed of light, which is much faster than the speed of sound.
Light travels much, much faster than sound. Light travels at 299792458 m/s while sound only goes 340.29 m/s.
Light speed is much faster than the speed of sound, ergo the light you see in lightning is visible, before you here the sound.
