1. ### I How much energy does a fission nuke actually release?

Thank you for the answer. I am very sorry I took so long. Somehow I must have forgotten to. :( Please accept my very late appreciation
2. ### I How much energy does a fission nuke actually release?

So I was trying to debunk a conspiracy theory involving bombs and I realized that I have a small problem with Einstein's equation: E=mc2 To be honest I haven't really understood how it's used... I mean, how far should the fission go until as much energy as E=mc2 is released? Does the matter have...
3. ### I Gravity in general relativity

So many questions, I don't know if they're actually scientific but if I'm correct, curving should not be possible without bending... I've forgotten the term but it has to do with the shape of the object, you can't cover a ball with a piece of flat paper without creating overlaps. If the same...
4. ### I Gravity in general relativity

So the other day I saw a YouTube video on how gravity works according to general relativity. From what I understand, objects bend space_time with their mass and create a shape which is close to a cone. Since objects only move forward in time through a straight line, the bent space_time makes...
5. ### Electromagnetic coil and capacitors vs resistance

Ohhhh Thank you
6. ### Electromagnetic coil and capacitors vs resistance

So energy for resistance is actually U= RIq? But what about coils and capacitors? Are those actually the same formula adjusted for coils and capacitors? If so, what is the mother formula. Cause the conserved energy in movement shows the same pattern of K=0.5mV2 which you could say that mass to...
7. ### Why the Frequency of Light Does Not Change Through a Medium

Frequency has nothing to do with what medium the wave is traveling through, it's only related to the source. See it this way: a EM full wave is produced when a charged particle goes up, down and once again up to the previous position... Now when it reaches a higher density medium the wave...
8. ### Electromagnetic coil and capacitors vs resistance

I'm not really sure if this is even scientific but while calculating how much energy is stored in electromagnetic coils and capacitors, pretty much the same formula is used: For electromagnetic coils it's U=0.5LI2 For capacitors it's U=0.5CV2 Why I think they're the same is that in a sense L to...

It says the app is unavailable for my country :/
10. ### Down syndrome -- level of mental disability

Hello I've read in my biology book "children with down syndrome develop different levels of mental and physical disability." But they all have an extra 21st chromosome... My question is what causes this difference?
11. ### Pressure in the core of the earth

I get it now, I just had to read everything a few times Thanks for the answer :)
12. ### Pressure in the core of the earth

Mass doesn't effect pressure on its own, it needs gravitational field and while g is at zero (g=Me×G÷re2 since Me=0 then g=0) the weight equals zero therefore the pressure equals zero I hope I made sense
13. ### Pressure in the core of the earth

I don't understand, if you draw where the gravitational forces are facing in the core you get that there are mass on the sides pulling everything in the very center out but once they're all the same size, the forces get canceled. Now about one mm away from the center we have the same thing but...
14. ### Pressure in the core of the earth

I'm an empirical sciences student who loves physics. While studying geology I learned that the core of the Earth is considered to be solid and the reason for that is because the pressure is too high. Although according to my calculations g( gravitational field) equals zero and when you go out...
