Upon the eruption of a volcano, can we also expect the geographically nearby volcanoes to erupt too?

Posted: 12 Jan 2020 04:54 PM PST

If you do not know yet, the Taal Volcano in Philippines just erupted and it is raining ashes in the entire Luzon. It hasn't erupted since 1977. Based on my basic knowledge of earth sciences and that the Philippines is a product of of oceanic convergence, am I right to expect that all nearby volcanoes in Philippines will erupt too? Isn't volcanic eruption an indication of an very active plate movement?

In winter bugs like spiders, flies and mosquitoes, seemingly die off. How is it that after the winter they're able to come back in such numbers? A layman would think the winter would cause an extinction of some insects.

How was it decided where astronauts would land on the moon?

Posted: 12 Jan 2020 04:47 PM PST

Is it a coincidence that the moon is tidal locked or did something cause it to be that way?

How does the bicarbonatebuffer system affect the different compensations for alkalosis/acidosis in the body?

Posted: 13 Jan 2020 12:40 AM PST

I have a trouble understanding som things So lets say we have respriatory acidosis/alkalosis

  • we wont be able to do respiratory compensation? We wont be able to use the bicarbonate buffer? We will use renal compensation, but will the bicarbonate buffer occur there?

In metabolic acidosis/alkalosis -we will be able to use respiratory compensation and therefore bicarbonate buffer? -we will also be able to use renal compensation?

What if metaboloc acidosis/alkalosi is due to a loss/gain of bicarbonate ions or loss/gain of H+? -will we be able to use the bicarbonate buffer?

Is the respiratory compensation solely dependent on the bicarbonate buffer?

Is there a link between the recent volcanic/tectonic activity?

Posted: 13 Jan 2020 03:17 AM PST

Is there a connection between the volcanoes/tectonic activity in the Philippines, New Zeland, Puerto Rico, Iran, Russia, Indonesia, and Japan? I assume the media just blows some things up and that's why I'm making this connection.

What does radar cross section actually mean?

Posted: 12 Jan 2020 10:54 PM PST

I've been binging stealth aircraft documentaries to fall asleep recently, and I realized I dont know what it would look like for a plane to have a radar cross section the size of a bird. If I could see radio waves, would I see the same number of photons but coming from a larger section of the sky, or would have the same angular measurement and appear to be a small object much further away?

[Thermodynamics] What is the theoretical maximum efficiency of a heat pump? (refrigerator or air conditioner, etc)

Posted: 12 Jan 2020 09:19 PM PST

The title.

I know total entropy must increase, but what does that look like? What is the maximum amount of heat that can be moved per watt?

Do Ritalin and other stimulants work different on a ADHD brain compared to an non-ADHD brain? Or do they have the same effects?

Posted: 13 Jan 2020 02:08 AM PST

I'm getting confused with all the different and sometimes contradicting information about stimulants I found on google. Some articles say that it helps "everyone" focus, so it doesn't matter if you have been diagnosed with ADHD or not, most effects would remain the same regardless.

As a side note, I have ADHD and been taking Ritalin for a while, I have never gotten any euphoric feeling or seen any "big" changes, I just feel a little less stressed and more "together". If I stopped taking it, I wouldn't care, so I find it hard to believe that some people could abuse it. What happens inside their brains to trigger that kind of "euphoric" response? Is it because they don't have ADHD? Does it work differently or it doesn't make any difference?

If you put a lamp in a fully mirrored room and then switched it off, would the room still be illuminated? If not, what happens to the photons?

Once land has become a desert (e.g. Sahara Desert or Gobi Desert) is there a way to revert it back to usable land?

Posted: 12 Jan 2020 08:39 AM PST

So I know due to climate change and other factors our deserts are growing. When I googled this subject I could only find information on stoping the spread of deserts. I could not find any information on if land that was previously desert could be fully reformed and use for something like farming or even if a forest could thrive in that area.

During the final step of chemiosmosis, the electrons flow from the intermembrane space to the matrix through ATP Synthase. During this process, ADP and inorganic phosphate turns into ATP. My questions is where does the ADP come from during the entire energy conversion thing?

How do inter-electronic repulsions differ in s and p orbitals?

Posted: 12 Jan 2020 05:14 PM PST

First ionisation energy increases from Group 1 to 2, and the reason is cited as an increase in effective nuclear charge despite inter-electronic repulsion from adding another electron into the s orbital. ns1 -> ns2

However, ionisation energy decreases from Group 5 to 6 (15 to 16), supposedy due to the inter-electronic repulsion caused by filling a p orbital despite increase in effective nuclear charge. np3 -> np4

In addition, the increase in ionisation energy from Cu to Zn is identical to the reason provided for Group 1 to 2. 3d10 4s1 -> 3d10 4s2

This seems to suggest inter-electronic repulsion between electrons in a filled orbital is stronger in p orbitals as compared to s, since increase in effective nuclear charge is the same for all the discussed scenarios (+0.65 according to Slater's rules).

Is it because p orbitals are more diffuse than s orbitals or is there another reason i'm not aware of?

Why do electrons transfer when you rub a balloon against hair?

Posted: 12 Jan 2020 02:08 PM PST

Hey I tried looking this up and I can't find the answer I'm looking for. I have to teach this soon (middle school) and I never learned it myself.

I don't understand why electrons transfer to a balloon in the first place while rubbing it against hair. I understand negative and positive chargers, but I don't understand why the act of rubbing or increasing surface area causes electrons to transfer over.

Thank you.
