Question: What Happens When You Fire A Gun?

If you fire a gun into the air, the bullet will travel up to a mile high (depending on the angle of the shot and the power of the gun). Air resistance limits its speed, but bullets are designed to be fairly aerodynamic, so the speed is still quite lethal if the bullet happens to hit someone. Can a bullet falling from the sky kill you? Feb 15,  · When you fire a bullet into the air, it typically takes between 20 and 90 seconds for it to come down, depending on the angle it was fired at, its muzzle velocity and its ca Author: Ethan Siegel.

As the laws of physics tell us, things that happen in space don't work quite the same way as in Earth's atmosphere, which means anything we do down here — from shouting across a room to pouring a glass of water — doesn't give us the same results out how to stop sleep mode in windows 7 orbit.

So what about firing a gun? As Vsauce's Michael Stevens shows in the video abovethe answers are fascinating, whether you've got a rifle or a water pistol with you. Shoot a cannon on the Moonsay, and there's a good chance you're going to get hit in the back by your own cannonball. Not a bad plot twist for the next Hollywood sci-fi blockbuster.

A lot about this depends on where you choose to fire your gun of choice. That's right — astronauts are constantly falling what happens when you fire a gun to Earth. However, despite how fast they're travelling, Earth is falling away from them at the same speed. On the Moon, it's different. The Moon is smaller and has less of a gravitational pull, so something orbiting the Moon doesn't need to be going at such a high velocity.

A very powerful gun, like a military cannon, would be able to fire a shot all the way around the surface of the Moon. What about firing a gun out in the middle of space? Well, it would simply drift into the blackness, forever alone, while the galaxies around it sped further away. Stevens goes on to examine the question we've all thought about at some point: how many shots of a water pistol would it take to put out the Sun?

We won't spoil the answer for you, you can watch the video above to find out, but it's complicated by the fact that the Sun is powered by the fusion of hydrogen nuclei. That means if you start squirting, the Sun is going to get bigger and burn brighter before you can eventually put it out.

A quicker technique would be to somehow blast the Sun into bits so that there's no longer the critical density needed for fusion to happen. In other words, you're going to need more than a few Super Soakers. And if you think that fire can't burn in the oxygen-free vacuum of space, you're absolutely right. However, modern ammunition comes with its own oxidiser chemical that can trigger the explosion of gunpowder, so all this space-bound gunplay kind of makes sense sort of.

Apr 02,  · Even on Earth, most shots fire so fast that there is no time for the oxygen from the air to participate in the combustion of the powder. So the gun will fire in space. If you put a gun in a plastic bag, it will burn under water. Jun 10,  · As Vsauce's Michael Stevens shows in the video above, the answers are fascinating, whether you've got a rifle or a water pistol with appvnstore.co a cannon on the Moon, say, and there's a good chance you're going to get hit in the back by your own cannonball.(Not a bad plot twist for the next Hollywood sci-fi blockbuster.) A lot about this depends on where you choose to fire your gun of choice. As long as you can fire the bullet that carries it’s own oxidizer it will mostly perform the way you’d expect: The weapon will fire (given by initial condition). In case of automatic weapon much of recoil will be absorbed by machinery and spent on reloading the next round from the magazine.

This is a topic which has been oft debated — and even become a subject of an opinion piece published earlier this week. As a recent study has concluded, Federal Air Marshals are extremely sleep deprived and over-worked.

What would actually happen if a gunman were able to gain access to the passenger cabin? More importantly, what sort of effects can we see from the impact of bullets inside the passenger cabin? A big, direct threat in an onboard incident of gunfire is the rapid depressurization of the cabin due to multiple perforations. When traveling at altitude, the inside pressure of an airplane is kept artificially higher than the outside pressure.

Why is that? As one travels further above the earth, air pressure precipitously drops. The fuselage of most passenger jets Boeing for example is lined with aircraft-grade aluminum. The pressure is kept at no more than 0. When a bullet is able to penetrate the passenger cabin and push out past the fuselage, there is now a hole of the rough dimensions of that bullet.

Taking the total volume of a passenger cabin and then the pressure differential caused by the hole into consideration, the proportion of that hole to the volume is not likely great enough to cause any major disturbances immediately. The effects will be instantly noticeable, though.

Thus, if the pressure in the cabin is greater than the external pressure outside the cabin, the cabin will leak air until the air pressure inside the cabin equals the outside. Based upon the second law of thermodynamics , this means that as the cabin pressure at P — pressure, T — temperature, and V — volume decreases, the temperature inside the cabin will also decrease.

At 25, feet in altitude, the ambient temperature is approximately The air pressure is also hPa — 0. So, the outside pressure of air is roughly equivalent to almost a third of what you would normally experience on the ground. This means that this tiny little puncture hole is passing gas as fast as it possibly can until the inside of the cabin gets close to the outside air pressure.

In most cases where a depressurization of the cabin is taking place, the pilot will attempt to decrease altitude to something with a far less difference in pressure. This action slows the rate of air being sucked out of the passenger cabin. Because the cabin is constantly circulating air inside the cabin, it may be possible that the cabin is able to significantly reduce its loss in cabin pressure.

What a bullet does effect is efficiency of the aircraft. The second the fuselage is punctured, there is an increase in drag which reduces the optimal output of the aircraft for the fuel it has. If the aircraft has to descend to a lower altitude to maintain cabin pressure, it will also result in a decrease in fuel efficiency. Fuel is something that the airline and the pilot calculate for a somewhat optimal trip.

While there are reserves, for especially long flights like San Francisco to Tokyo — a bullet puncturing the fuselage would definitely impact the entire flight.

But then again, an exchange of bullets of any kind on a flight would certainly do that as well. Connect with us.
