In a vacuum a projectile will maintain its launch speed (muzzle velocity) until gravity pulls it to earth or it strikes something in its path. In absence of gravity it will maintain straight-line flight and velocity until it strikes something. Atmosphere creates drag which slows bullets dramatically.
Yes - much faster.
According to the old black & white TV series, Superman was faster than a speeding bullet. Besides Superman, many things can be faster. However, light is always the fastest traveling thing, being MUCH faster than a bullet. Some airplanes and missiles can travel faster than some bullets.
the atmosphere determines rate of evaporation. if the atmosphere is as dense as a liquid within the atmosphere there is no evaporation at all. on earth, cooler atmospheres are generally less dense, so it's not cooling the liquid alcohol as much as providing it with a supply of less dense atmosphere that will make a liquid, alcohol, evaporate faster. on the extreme, putting a liquid into a vacuum will cause it to almost immediately evaporate, a.k.a. standardize the temperature and pressure of its atmosphere. there is really no such thing as evaporation as much as there is homogenization, standardization, of its atmosphere.
No, there is no snake fast enough to strike at a bullet. If it did, it would die.
The bullet will travel as fast as it would on earth (possibly a little faster, due to the lack of air resistance in the barrel). Once it left the barrel, it would continue with the same speed until slowed by gravity, or it entered a planetary atmosphere- or hit something.
No. The bullet will actually travel much slower due to wind resistance.
They are exactly equal. The bullet travels faster, and weighs less. The gun recoils more slowly, but weighs much more.
According to the law of action and reaction, the bullet and the gun absorb the same amount of energy, just in inverse diretions. But the bullet is much lighter and thus will go much faster.
No, a bullet travels faster than water. The speed of a bullet can vary depending on the type and caliber, but it is generally much faster than the speed of sound in air (about 343 meters per second or 1,235 kilometers per hour), while water only flows at a few meters per second.
Very, very little, as Mercury's atmosphere is almost a vacuum only minute traces of gasses are found.
Based on a little research I just did, the F117's maximum speed is just under Mach 1 (the speed of sound). Some bullets travel much slower than that, and some travel much faster, so it just depends on which bullet you're referring to.
Not that you would notice. The moon lost it's atmosphere long ago- not enough gravity. Conditions on the surface are pretty much pure vacuum.
