Thank you very much for your time! I guess I'll keep looking for now :) There must be a way of doing it, I hope!

Hello! My name is Fabrizio, I'm a high school student doing some research on the atmosphere. Right now, I'm trying to figure out how much matter escapes into space via Jean's Escape. I've found several formulas, all of which require me to know what the amount of particles per m3 of a certain...

Well I don't know how much volume they might take up, that's why I'm asking. And I'm not implying that I am able to see that or would be able to, I'm imagining how that would look by comparing the N2 molecule to a basketball so that I can explain where I'm coming from by trying to understand how...

Hello! I suppose you didn't read my description of the question. My question is how much space a molecule occupies effectively in a gas of varying density, pressure and temperature like the atmosphere (from 0 to 80 thousand meters).

Hi! Thanks for your answer. I'll look up that concept and see how I can apply it. I've thinking of what I actually calculated with my formulas, and I have the impression that what my formulas calculated is the volume 'allotted' to each molecule, so like if someone else and I were in a huge house...

Hello, I'm trying to calculate what is the effective volume of a molecule of N2 in the most precise way possible (I'm a high school student so "in the most precise way possible" is probably not that precise considering my lack of advanced mathematical knowledge). What I want to know is, if I had...

Hello! I will bring that suggestion to the professor I'll be working with, maybe we can work something out with the equipment available. Regarding the disposition, I believe I'll be good there, because no one else in my city ever went to the professor I am going to be working with to suggest...

Hey! I have no idea which university is better for you, but still, wanted to wish you good luck! Hope you have a great phd experience! Greetings!

Hi! I'm sorry for the late reply, but thank you a lot for the suggestion! I wanted to do the research myself and come up with something on my own to show personal interest in the subject to the professor who will be helping me, but as you say, even if I come up with something interesting I might...

Hello! First of all, thank you taking the time to read this. I'm a high school student currently about to begin my last year (I'm from Argentina so here we start in March) and would like to study physics in 2020. Because of that, I contacted a university here and they told me that if I wanted...

Thank you very much for your answer. From now on, I will try to look for the qualifier, as the previous comment said, because the 'how far' sounds a little bit tricky to me so far!

Thank you for your answer. Thankfully, I was able to understand how to solve these kind of problems. My only issue was about what the problem was asking me to figure out. Thank you, seriously! From now on, I will only pay attention to what it says after 'how far' to interpret what the statement...

1. Problem statement: "An object is thrown horizontally with an initial speed of 10 m/s. How far will it drop in 4 seconds?" Homework Equations Δx = v0x.t Δy = v0y.t + 1/2(-g)t2 The Attempt at a Solution [/B] When I first read it, I thought that 'how far' means Δx, since when someone says...

Oh my god, this explanation is so brilliant and simple at the same time, my respects to Stanford haha, thanks for sharing this, and to all of you who tried to solve the riddle with your own hypotesis and methods. Although I'd looked up the riddle on the internet I'd found nothing before, so it's...

Thanks @rcgldr for that very detailed answer, so all in all, the riddle's provided answer seems to be correct. The gravity example really explains everything more clearly if you take into account the balloon example which is simpler than the birds one. Also appreciate your answer @FactChecker...
