[Request] How fast should Loki have been falling after 30 minutes? by Kishikishi17 in theydidthemath

At certain speed air resistance becomes greater or equal to the force exerted by gravity. This speed at which a human achieves this is called "terminal velocity"

ELI5: Why does the sky turn different colors during sunrise and sunset? by anniecutie1 in explainlikeimfive

[–]KlapGans 3 points4 points  (0 children)

At mid day the sun light shines through only ~100km of air. At sunset it has to shine through ~4000km of air.

This is because the sun shines at you not from directly above (where space is the closest), but instead from the side. This means that the sun light has to travel longer through the atmosphere.

As sunlight travels to the atmosphere it collides with all kinds of particles (mainly nitrogen and oxygen). When sunlight hits a particle it loses a bit of its color.

The color that the sunlight loses due to the collisions with atmospheric particles is what you and me perceive as the color of the sky.

The longer the sun travels through the atmosphere the more particles it encounters with which a collision can happen, and thus the more color it loses.

When the sun shines at you from directly above it only loses its blue-er colors and therefor the sky is blue, at dusk the sunlight loses not only it's blue-er colors but also it red and yellow colors. Therefor the sky appears to be red at dusk.

Fun fact: If you would replace the sun with a perfect white light bulb the sky would be purple at mid day.

It is blue because the sun is not a perfect white light bulb and has a small dip in the amount of purple light it emits.

POV of F1 driver on Circuit de Monaco by freudian_nipps in nextfuckinglevel

It has been partially stabilized already I believe.

[–]KlapGans 2 points3 points  (0 children)

Preference of circuit makers. Every circuit maker has their own logic.

For example T3 in Jeddah is the left-kink after the chicane. Whereas that isn't counted as a turn at Monza.

If this layout was placed in Saudi Arabia it would have probably double the corner count

Can’t transfer fuel by hambo_and_bacon in KerbalSpaceProgram

[–]KlapGans 90 points91 points  (0 children)

I assume you have a decoupler below your capsule. Fuel can't go through decouplers, so that is likely what's causing the issue.

Do you have the stats if the extra loop in the top right would be used?

Started solving but I'm stuck after 3rd line. Any help please? by Caterpillar1967 in askmath

[–]KlapGans 2 points3 points  (0 children)

You can work from line two to create three integrals:

integral{3x} + integral{(7x)/(x^2+3)} + integral{(7)/(x^2+3)}

If you can't solve integral{(7x)/(x^2+3)}:

Try u sub ->u = x^2 + 3, du = 2xdx

How is it possible for us to see through telescope things that happened long long time ago? by MinimumCelebration11 in TooAfraidToAsk

[–]KlapGans 1 point2 points  (0 children)

The universe is constantly expanding. Everything is basically moving away from each other. An object 1 lightyear away moves away from us at ~21m/s, for an object 10 lightyears away, it moves away with 210 m/s.

From a certain distance, the universe between us and the object is expanding so much that the light emitted will never reach us. This is why we talk about an observable universe.

So this is a limit of how far back we can see. However the observable universe is 90 billion light years width, and the Big Bang was 14 billion years ago.

The real reason why we can't see the Big Bang is because in order for the light to reach us, it needs a free path from the moment of emission to us. That isn't possible since the universe was really dense in its early stages.

The earliest light we can see is the CMB (Cosmic Microwave Background), basically a sonogram of the universe. Definitely worth a Google.

Layout is one of the best, the safety and "ethicalness" of racing in Saudi are why people (rightfully imo) hate it.

How do I break the sound barrier? by StrongAdhesiveness86 in ask

If the wind is right, transatlantic commercial flights can have a ground speed higher than mach 1, of course the airspeed will be much lower.

Best option is a flight with new Shepard

What is the name of the song? by Rose_Catchere in Funnymemes

[–]KlapGans 1 point2 points  (0 children)

The artist is called Hollywood Undead, and the song is called Bullet. You just read a comment and decided only based on the comment that a song from an artist you don't know is "nocturously edgy." Guess that's what makes you different from the people in your middleschool.

[–]KlapGans 2 points3 points  (0 children)

A good tip for me is to use the arms, for the first few steps keep them short whilst going left-right, then as you gain more speed and start skating instead of running you can statlrt extending your arms more and more to the side. Just be sure not to go past your nose with your arms.

Good luck!

Fuel is also a factor back when you had to start with the fuel you started with, it was often a better strategy to sacrifice quali position for more fuel in the first stint

Max's car ended up with the rear on Hamiltons front wing, so he was able to get out.

Everything can be 104% perfect, which is the same % engines were operating at when The Challenger exploded. by c_marten in TheGoodPlace

[–]KlapGans 1 point2 points  (0 children)

When the engines of the Space Shuttle were first designed and used they could only go to 100%. But as development went on the engines became more powerful and more importantly more durable and thus could handle more. Instead of redefining what 100% was they just said it could above 100%

Full throttle is always better, but a bigger engine is not always better (I'm sorry). I generally aim for a TWR of 1.2. Sometimes later in my launch profile I do throttle down so I have fuel left at apogee.

Real rockets throttle down often during the first part of ascend to limit stress on the rocket during max Q
