does flying through clouds have any effect on the speed of an aircraft?

Posted: 18 Nov 2018 07:52 PM PST

Title pretty much says it all.

Is there any effect on the speed of an aircraft? Clouds do have mass correct?

What effect would anti- depressants have on someone who is not depressed?

What is the critical mass of gas required for it to stick together in deep space due to gravity and not disperse due to diffusion?

Posted: 19 Nov 2018 04:58 AM PST

I just found out that while mars has about 1/10th the mass of earth it has 38% of the gravity. This suggests a non-linear relationship between mass and gravity at the surface. What causes this effect? [Physics]

Follow up question: Does this effect mean that the gravity on the surface of planets that are significantly larger than earth would be survivable for humans?

Why is it when you "haaaa" hot air comes out but when you "huuuuu" cooler air comes out?

Posted: 18 Nov 2018 08:52 PM PST

Does the air come out of different places in my body? If so where does the different air come from?

What happens to the vacuum energy next to mass agglomerations?

Posted: 19 Nov 2018 04:38 AM PST

  1. If gravity changes the space curvature, does that mean anything for the vacuum energy next to big masses like galaxies or black holes?
  2. Does space gets more "compressed" if it gets curved?

  3. Will the vacuum energy be higher per space-unit if space is "compressed" or doesn´t it change at all?

  4. How much vacuum energy is there? Wiki doesn´t know.

Thanks!

Objects that reflect only non-visible wavelengths?

Posted: 19 Nov 2018 12:31 AM PST

I had a few questions pop into my head last night. Hypothetically let's say there is a material that only reflects wavelengths of non visible light, such as ultra violet or infra red, or maybe they only reflect radiation like microwaves or x-rays. What would those materials look like to the human eye? Would they be completely black if they only reflect non-visible light? Do any of those materials exist? Are there any practical purposes for those kinda of materials. The sooner I get an answer the sooner I can sleep easily.

What makes Ciliac Disease so hard to cure?

Posted: 18 Nov 2018 06:55 PM PST

I happen to have it, though I have done little research into it. I ask this for three reasons:

New daughter (biological), is this a genetic concern? (I was adopted, no genetic history)

Serving in the Army, sometimes tough cookies, literally. Will I become incapable of working at peak performance due to this?

What other factors does this put me or my lineage at risk for?

Substrates Reactions Growth of Graphene?

Posted: 19 Nov 2018 12:53 AM PST

Hi,

Can anyone tell me what is the type of substrate used (elements it is made up of)? It appears to be a solid. What is the reaction of the layer of graphene particles on the copper surface that are from the reaction of the gases after it is broken down? Is there a reaction between the graphene particles and the substrate? If there is, what is the reaction that occurs? Does the layer of graphine react with a chemical which forms a graphene solid (the layer is solidified in the chemical).

If someone could please help, thank you.

Zackhie

This video shows the image (diagram) of the reaction

Is time exactly symmetrical? If we were to rewind it would it play back as the reverse of it playing forwards?

How does blood "know" where to clot?

Posted: 19 Nov 2018 02:09 AM PST

Like, how does it "know" it needs to clot as soon as a wound is bleedind?

The sunset in Barrow, AK for the final time for 66 days, is there somewhere else in the world that the sun won’t go down for that long?

Posted: 18 Nov 2018 08:53 PM PST

Pretty much the title. If the sun is setting in Utqiaġvik (Barrow) until January is there an opposite event happening elsewhere?

What happens to electron orbitals in plasma?

Posted: 18 Nov 2018 04:53 PM PST

My understanding of plasma is a gas that has free flowing/ non localized electrons. Does this mean that their are no orbitals for matter in this state or are only the valence electrons free flowing?

Does fog absorb or reflect light?

Posted: 18 Nov 2018 08:58 PM PST

I've always wondered this. When there's snow on the ground, my small town is illuminated during a foggy night. Is the light from town being absorbed by the fog, making it seem brighter? Also relevant to driving at night; during intense fog I can't see lights that are a mile or more away. What is happening?

How did allergies (specifically anaphylaxis) evolve in humans? I just don’t get how closing off the airway in response to a “pathogen” helps at all.

What’s the current status of Zika? The news hasn’t been reporting it as threatening as it was before- is this because the news is bored of it and it is just as bad as it was a year or ya ago or is it actually subsiding? Do we have a vaccine available?
