Can paper stop a bullet?
The results, according to KTUL News: Two books stopped a handgun fired at close range, and three stopped a round fired from an AR-15 semiautomatic rifle.
50-caliber rounds into stacks of paper.
Surprisingly enough, two sets of five reams of paper — that’s 5,000 sheets in total — weren’t enough to stop the a ..
Can you see smoke in space?
Thick smoke covering the western U.S. was so extensive it was “easily visible” from space, according to new satellite images captured by NASA, showing the impact wildfires there have had on the atmosphere as blazes continue to burn.
Does the sun need oxygen to burn?
The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. … Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!
What does fire look like in space?
Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow. … The result is that space flames can burn on much less oxygen than we expect on Earth, which means fires that burn longer.
Can things explode in space?
Acute exposure to the vacuum of space: No, you won’t freeze (or explode) … The absence of normal atmospheric pressure (the air pressure found at Earth’s surface) is probably of greater concern than temperature to an individual exposed to the vacuum of space .
Can you light a fire on the moon why?
Fire can not be lit on the moon because there is no oxygen there. without one of these elements it is impossible to lit fire.
How long would it take to die in space?
Water and dissolved gas in the blood forms bubbles in the major veins, which travel throughout the circulatory system and block blood flow. After about one minute circulation effectively stops. The lack of oxygen to the brain renders you unconscious in less than 15 seconds, eventually killing you.
What does space smell like?
sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts. Image source: LubosHouska; CC0.
Can a gun fire on the moon?
Gun: Yes. The oxidizer is within the gun powder, so a gun will fire in the vacuum of the Moon. The bullet will travel significantly farther, because it will fall slower and there will be no air resistance.
Do astronauts carry weapons?
Cosmonauts regularly carry handguns on their Soyuz spacecraft — and actually, that’s not unreasonable. … For decades, the standard Soyuz survival pack has included a gun. And not just any gun, but a deluxe all-in-one weapon with three barrels and a folding stock that doubles as a shovel and contains a swing-out machete.
Can you light a lighter in space?
There’s a difference between zero gravity and no oxygen. For example if you’re on the ISS, there’s low gravity, but there’s still oxygen, the fuel, which comes from the lighter, and an ignition source. … The lighter uses the same spark and flame tech as a space engine…so yes.
Can there be smoke in space?
A spaceship orbiting earth is moving fast enough to break gravity and the vacuum of space has no density. In this case the smoke may expand in all directions, or the direction of force applied by an explosion and continue moving at the same direction and velocity of the object that created the ‘burn’ process.
Can astronauts smoke cigarettes in space?
Well astronauts are not allowed to smoke in space craft. … If someone in space craft smokes, he or she will start polluting the air, which may cause suffocating conditions in space crat. That is leathel for life. Second thing, smoking need lit up of cigarettes which requied lot of oxygen.
Can fire burn underwater?
Combustion needs oxygen to take place, if you provide an oxygen source by chemical or mechanical means, fire can burn underwater. A chemical reaction that gives up a lot of heat may stay burning for a little bit, but remember water has a high heat capacity and would cold the reaction quite fast.
Would a candle work in space?
But what happens when you light a candle, say, on the International Space Station (ISS)? “In microgravity, flames burn differently—they form little spheres,” says Williams. … Unlike flames on Earth, which expand greedily when they need more fuel, flame balls let the oxygen come to them.
Can u get pregnant in space?
As a result NASA’s official policy forbids pregnancy in space. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon.
Do female astronauts wear bras in space?
Women don’t wear bras primarily for support, they’re also worn as a thick layer of coverage so detailed outlines are not visible. Although the support portion may not be necessary in space, in a professional setting the extra layer of coverage may still be preferred by some.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
What happens if there is a fire in space?
Fire is a different beast in space than it is on the ground. When flames burn on Earth, heated gases rise from the fire, drawing oxygen in and pushing combustion products out. In microgravity, hot gases don’t rise. … Space flames can also burn at a lower temperature and with less oxygen than fires on Earth.
How does fire burn in space without oxygen?
But odd things happen in space, where gravity loses its grip on solids, liquids and gases. Without gravity, hot air expands but doesn’t move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire.
How many dead bodies are in space?
However, of the roughly 550 people who have so far ventured into space, only three have actually died there.
Would you die instantly in space?
Without air in your lungs, blood will stop sending oxygen to your brain. You’ll pass out after about 15 seconds. 90 seconds after exposure, you’ll die from asphyxiation. It’s also very cold in space.
What happens if an astronaut rips his suit?
A space suit leak is a big deal. In the Shuttle suit, an astronaut can survive 22 minutes with a 1/8″ hole in his suit. At that point the pressure will drop to where he is likely to suffer permanent brain damage, if he survives. … If there is a large tear, the astronaut might have a few seconds to live.
Are astronauts allowed to drink alcohol in space?
“Alcohol is not permitted onboard the International Space Station for consumption,” says Daniel G Huot, spokesperson for Nasa’s Johnson Space Center. “Use of alcohol and other volatile compounds are controlled on ISS due to impacts their compounds can have on the station’s water recovery system.”
Do astronauts get paid?
Astronauts’ annual salaries are determined using a government pay scale, and starting out, typically fall under two grades: GS-12 and GS-13. According the US government’s 2020 pay scales and a NASA job listing, a civilian astronaut in 2020 can earn between $66,167 and $161,141 per year.
Will a gun fire in space?
Fires can’t burn in the oxygen-free vacuum of space, but guns can shoot. Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe. No atmospheric oxygen required.
Is there oxygen on the moon?
Oxygen on the Moon Based on lunar rock samples returned to Earth during the Apollo missions, scientists know that the moon’s soil, or regolith, contains about 40 to 45 percent oxygen by weight. This makes oxygen the most abundant element on the moon’s surface.
