Snedige spørsmål og svar.

Anbefalte innlegg

Ok, vi har allerede Snedige ting du lurer på-tråden, der du spør snedige spørsmål og får eventuelt svar. Men hva med alle de spørsmålene som Google gir deg et svar på før du rekker å spørre de i tråden?

 

Da tenkte jeg, hva hvis vi da har en egen tråd der du poster de snedige spørsmålene du kommer på, men også svarene du finner! Da kan du komme tilbake hver gang du finner et nytt snedig spørsmål og svar som du har lyst til å dele, for så å lese alle de andre snedige og interessante bidragene andre har kommet med. Er dette en tanke som dere andre også liker?

 

I så fall, vi burde ha en liten mal for spørsmålene, så det blir lettere å bla seg igjennom tråden:

 

Er det mulig å avfyre en pistol på månen?

 

 

Yes, you can fire a gun on the Moon, despite the absence of oxygen.

 

A gun "fires" because of a sudden impulse delivered to the gunpowder by the trigger. The gun powder then explodes, imparting a lot of energy to the bullet which shoots out of the gun's barrel. In order to trigger the explosion of the gun powder, you need an oxidizer that will initiate the chemical reaction. On Earth, a common oxidizer is, well, oxygen: that's what makes fires burn and cars rust! Despite the abundance of oxygen on Earth, however, most gun ammunition comes with its own oxidizer "built in", so to speak. The result is that a gun can fire even in the absence of oxygen, such as on the Moon.

 

This technology is also useful in certain circumstances on the Earth; most notably, sometimes one wishes to cause an explosion on the ocean floor (say, for exploratory purposes), where oxygen is in short supply.

 

Håper dette er noe som slår an, fordi jeg er en som elsker snedige spørsmål!

Bra initiativ Coffey!

Mitt bidrag: Hva er en lynkule?

 

Ball lightning is a debated and controversial atmospheric electrical phenomenon. The term refers to reports of luminous, usually spherical objects which vary from pea-sized to several meters in diameter. It is sometimes associated with thunderstorms, but lasts considerably longer than the split-second flash of a lightning bolt.

 

Laboratory experiments have produced effects that are visually similar to reports of ball lightning, but it is presently unknown whether these are actually related to any naturally occurring phenomenon. Scientific data on natural ball lightning are scarce owing to its infrequency and unpredictability. The presumption of its existence is based on reported public sightings, and has therefore produced somewhat inconsistent findings. Given inconsistencies and the lack of reliable data, the true nature of ball lightning is still unknown. Until recently, ball lightning was often regarded as a fantasy or a hoax, but some serious scientific discussions and theories have attempted to explain it.

Bruker vi bare 10% av hjernen?

 

 

The 10% of brain myth is the widely-perpetuated myth that most or all humans only use 10% of their brains. By association, it is often suggested that by some process a human being may harness this unused potential and in so doing inherit several magnitudes more intelligence.

 

Though many factors of intelligence may be increased with training, the idea that large parts of the brain remain unused is without substantial foundation. Although many mysteries regarding brain function remain, every part of the brain has a known function.

 

 

uff, dårlig av meg, det kommer sikkert noe bedre senere.

Hva er det man hører når man "knekker" fingrene?

 

 

When you crack your knuckles, you're essentially pushing the joint into or out of its normal position. A thick, clear lubricant called synovial fluid is found in the joints between your bones. When you crack your fingers, you cause the bones to pull apart, and the pressure on the synovial fluid is reduced. Bubbles form and quickly expand and then burst.

 

The bubble forms in a process called "cavitation." Once you've cracked your knuckle, it takes about 25-30 minutes for the gas to dissolve into the joint fluid. During this time, you can't crack the knuckle again. But once the gas is dissolved, cavitation is once again possible, and you can start popping your knuckles to your hand's content.

 

 

 

Hvor stort er verdens største fly?

 

 

The An-225 Mriya is a strategic airlift transport aircraft which was built by the Antonov Design Bureau, USSR. It is the world's largest fixed-wing aircraft. The design, built to transport the Buran orbiter, was an enlargement of the successful An-124 Ruslan. Mriya (Мрiя) means "Dream" (Inspiration) in Ukrainian.

 

The Antonov An-225 is commercially available for flying any over-sized payload due to the unique size of its cargo deck. Currently there is only one aircraft operating.

 

DIMENSIONS:

Length: 84.00 m

Wingspan: 88.40 m

Height: 18.20 m

Wing Area: 905.00 m²

 

WEIGHTS:

Empty: 285,000 kg

Max Takeoff: 600,000 kg

Kan man unslippe kuler ved å oppholde seg under vann?

 

 

Ifølge Mythbusters er svaret ja! http://www.metacafe.com/watch/125635/50_caliber_sniper/

Den korte versjonen: Kulen deler seg opp ved kontakt med vannoverflaten, og blir ikke-dødelig. Jo raskere kule, jo tryggere er du.

 

En advarsel, dog: Det vites ikke hva som skjer hvis prosjektilet blir avfyrt rett nedover.

 

 

Håper den tidlige tvisten er akseptabel?

Hvor mange kilometer er et lysår?

 

 

Siden hastigheten på lyset er 299 792 458 meter i sekundet, tilbakelegger lyset enorme avstander; i vakuum er den omtrent 9 460 000 000 000 km, eller 9,46 billioner, km.

 

 

 

Hvor stor er Solen i forhold til den største stjernen vi kjenner til?

Inneholder virkelig et astronomisk svart hull en singularitet, et objekt med null volum?

 

 

Our theories predict that all the matter in a black hole collapses to a geometrical point of radius zero, which is called the singularity. There is however no way to observationally test this theory. Perhaps the matter is really infinitely compressed into a singularity, or perhaps there is some as yet unknown force to prevent an infinite collapse. In the latter case the matter is compressed to a very small size, but not to a point.

 

We can not observe this singularity to find out because the singularity is cloaked by the event horizon. Nothing can escape from within the event horizon. No light that might allow us to see the singularity can escape. No instruments can probe the singularity and return from within the event horizon to tell us about the true nature of the singularity.

 

Event horizon er det svarte du ser, der du må være raskere enn lyset for å slippe unna. Er ikke sikkert det går da engang..
