Has "international edition" or "international student edition" of Fundamentals of aerodynamics(John Anderson) SI units and what is the difference between US version? This is pdf "SI units" version, but I see english units again, page 34 for example, so what is SI units version...

Thank you guys for taking the time to read this - I'm decently struggling with first year and need some tips on how to properly conceptualize problems and learn what the right approach is on certain problems. Have a wonderful day, again thank you for checking this post out!

I am curious to know if there are any notable differences in the amount and difficulty of the questions between Fundamentals of Physics Extended 11th Edition and Principles of Physics 11th Edition. Additionally, I would like to know if both textbooks treat the theory in the same manner in terms...

There is a difference in the questions (amount, difficulty) between fundamentals of physics extended 11th edition and principles of physics 11th edition? And both textbooks treat the theory the same in terms of derivations?

It's not a homework. I came up with this problem myself. Trying to understand fundamentals of electronics. Do you know how to solve it? Is voltage somehow related to electron energy levels? What knowledge should I gain to be able to solve problems like that? Thank you! If we ground the cathode...

Hey there, I'm aware this is a bit of a stupid question, and I think that I understand the principle fundamentally, however, my intuition is still having a little trouble catching up, and I'm trying to figure out if it is because of an important detail that I have missed/misinterpreted. I think...

Unbiased circuit (no driving voltage source) ************** Fig 1 The N-type material has a tendency to donate electrons to the P-type (i.e. absorb holes from) across the PN junction via diffusion current exclusively within the conduction band of both materials. It does so after those...

I am a mechanical an engineer with a few years of experience. Most of the work I do is transient, structural finite element analysis. I have gotten reasonably competent at building models and pumping out results, but I regularly come across gaps in my fundamental knowledge. I have been doing...

Shouldn't all black holes have the same density? Since all are assumed to contain a singularity (infinite density). Also, depicting spatial curvature due to gravity in terms of a two-dimensional fabric is very misleading. Whether you're imaging a black hole, or a star. We live in a...

Hi. I have a problem and I will be so grateful if someone can help me with this. I would like to know are there books that are similar to P.Orlov: Fundamentals of machine design 1,2 and 3. The book should include pictures of what is wrong and better solution of certain design. Thank you in...

Mixing with a Common Drain. Two tanks, each holding 1 L of liquid, are connected by a pipe through which liquid flows from tank A into tank B at a rate of 3-a L/min (0<a<3). The liquid inside each tank is kept well stirred. Pure water flows into tank A at a rate of 3 L/min. Solution flows out of...

Hey everyone! I have a course-book related question. I hope this is the correct thread. If not, please let me know. I want to prepare myself for our national physics olimpiad and I heard about a very useful book named Fundamentals of physics by David Halliday. We have the extended 5th edition...

Hi, this is my first time posting, I'm glad there is a space like this where we can share our doubts and hopefully get some help from other students. As you can see on the image above, there's a KVL applied to the circuit in practice problem 2.6, but my question is the following: On equation...

I have a copy of Fundamentals of Physics by Halliday, Resnick and Walker. The book has 952 pages plus appendices. There are many entries in the index which point to pages beyond 952. For example if I look up "dark matter" it points to page 1136. There's no such page. I don't know what's...

I was reading Einstein's book on Relativity. He says something about a contradiction between the law of Propagation of light in vacuum and the principle of relativity(which he calls in restricted sense).What is this contradiction?How does it lead to Einstein's conclusion that time and distance...

This is a general question about tension in a string. If we have a string that makes an angle theta of 10 degrees with the vertical, what would the tension in the string be. If we assume a mass of 0.025kg at the end of 0.8m long string, I calculate that the force acting opposite mass x gravity...

Hello, what level of math should I have before learning this book?

Hi, My teacher tasked me with a complex waveform question, i have looked for some time to find out how to tackle these, but i still do not know where to begin. Any help would be greatly appreciated, not look for an answer just a method. $$i=12sin(40*\pi t) + 4sin(120* \pi t - /3\pi) + 2sin(200...

I honestly don't like this text at all. Is there any other calc based physics textbook out there? I just got textbook from the library which is titled: Physics for scientists and engineers 1st edition Please if there's any book out there post it!

Homework Statement http://prntscr.com/daze68 What I don't understand: 1. "P be a polynomial with degree n" do these equations satisfy this description?: $$p(x) = (x^2 + x)^n$$ $$p(x) = (5x^2 + 2x)^n$$ etc. 2. "C1 is a curve defined by y=p(x)" c1 is essentially just the curve of the...

It's been a while since someone last posted on this thread, and I haven't had much time to start learning, much to my dismay (due to family events and other things that kept me occupied). I have a very late edition of the Fundamentals of Physics (6th edition). Is this too watered down for a...

Hello, I was told that I could post questions related to Financial Accounting Fundamentals on the Pre-calculas Math section of Physics Forum. But everytime I post questions related to this topic, I don't get any replies or help. Am I posting in the wrong category??

Hi, that's my first post here.First of all – I do not want to ask someone to calculate something for me. I did my best (I hope correctly) – can you briefly check it and answer my additional questions? I am especially interested in these questions – I always have some doubts during calculations...

How does an electric charge produce an electric field? How is this field maintained over time without the input of energy? When the charge moves, why is or isn't there any remnant of the field left behind in space?

Dear all, I have a hard time in understanding the fundamentals of convection. Let's say we blow a fan over a hot surface. From fluid mechanics, I know that there is a velocity boundary layer due to the viscosity and no slip condition. The velocity gradient is kinda parabolic. Ok...

I know that the refractive index is determined by a material's dielectric constant and magnetic permeability. It's also true that we can treat the refractive index as a complex function with the imaginary part giving you an absorption spectrum. You can then get the index of refraction from...

Forgive the broadness of the question. I know this is a huge concept which entire books have been written about. I am an amateur computer programmer entering my first object-oriented class soon and want to get some things out of the way. When I write lines of code how does the computer know what...

I've been into physics for years now but no matter how much a study, i find that i always lack basic knowledge that others seem to have. I was wondering could someone provide me (if possible) with a list of fundamental concepts every physicist should know? i imagine the list might be to long or...
