Hydrogen atoms are generated in an excited state where the electron occupies the 2p orbital. The excited sample of atoms then emits radiation that is directed to an unknown metal. The radiation ejects electrons with kinetic energy 8.77 x 10^-19 J. Given the data in the table below, identify the...

I've always had problems with learning physics. It's not that I don't like it or can't do the calculations, but rather the memorization of thousands of equations that can easily derived. Of course, memorizing the important ones are necessary, so we don't have to constantly rederive them. So, my...

An object's motion can be described by a function that relates its position x (in meters) to time t (in seconds). Let this function be x = 6t2 + 2t + 4 What is this object's acceleration? I tried inputting 6, but it counted it wrong...

This is my second year of college, but my first year of EE (just decided that was the major I wanted.) In addition to a gen ed class (american government) and math classes (calc 1, and stats 1) I have a couple of EE classes, but I have no idea what to expect. I was hoping maybe some of you...

I have finished my first year of my undergraduate, taking an Honors BSc in Math with a minor in Physics. I am planning on going to grad school after my undergraduate, and I want to be sure I am not taking too many first year classes. How many first year courses (100 level) courses would you...

I have a desktop with P4 and a gig ram(using right now). I didn't want to take it to my college since it is 1600 KMs from home and carrying a desktop there is follishness(laptop seems to be a better option). So is it mandatory to take computer to college or i can manage even without a computer...

I will be starting my first year as a phd physics student in the fall. I'm trying to get everything I need to start my first year of grad school. The one thing I'm not sure of is whether I should get a laptop or a desktop for graduate school. I am going into theorectical amo. Also I plan to...

Just finishing my first year of Physics, what topics are most likely to be in year 2 of a usual 'Maths for Physics' module if I wanted to start studying the Maths now? And what do you think would be the most useful topics to become quite fluent with?

I am a first year community college student. I plan on transferring to North Carolin A&T State University, and majoring in mechanical engineering. I am having trouble getting any meaningful advice. If anyone can offer any advice it would be greatly appreciated.

I've heard that using Lagrangians to solve mechanics problems is much more efficient and easier than using Newton's laws. In your opinion, is it too early for a student to learn lagrangians for a first year due to a lack of exposure of the mathematics required?

I really do think my GPA is going to be very low as I adjust and change my study habits accordingly. The first set of midterms shocked me and I did very poorly which I attribute to my inefficient study habits. Is it normal for university students to have a bad first year GPA and is my first year...

I am a 3rd-4th year student planning to try and get into graduate school in my field of study. But I got some terrible marks in my first year in courses relating to my program (science and math courses), and in a non-related course. Since some universities specifically require an undergraduate...

In high school, my homework never used to take me more than 2 hours per day, on average. Now that I am in university, I've increased the time I spend on problem sets+ assigned readings to 6 hours per day and I'm just struggling to keep up especially due to the fact that problems are more thought...

Hello, I'm currently attending the University of Calgary in the Double Honours program in Astrophysics and Applied Mathematics. I attended the ISSYP summer program at the Perimeter Institute for Theoretical Physics in the summer and wrote a collaborative paper that derived a gauge theory...

Here is my timetable: [PLAIN]http://img171.imageshack.us/img171/5438/ubc.png I have 25 hours or classes for my first term and 26 hours for my second term. HOWEVER the biggest problem with this is that I have 5 courses for my first term and 7 for my second. Do you think I can handle 7...

Hey everyone, I am going to McGill University in the fall, and I want to major in Physical Chemistry second year. However,I didn't take physics in high school because... well, when I was 16 years old and out of Grade 10, I didn't know what I wanted to do for a living, and not taking physics...

I'm going to start college in the fall for EE and I made a 5 on my mechanics AP test and a 4 on my E&M AP test. I've been told that these are two weeder classes at my university and while I am confident I could make an A in both with hard work, I'm starting to think it might be smart to save...

Hi. I'm finishing my first year of Undergraduate CS with relative ease. We have the opportunity to take 30 credits worth of classes in another field of study (minor). I'm thinking of taking either an Applied Math or a Physics minor. For Math I was thinking about taking classes in abstract...

What should you expect as a physics major when you first enter college? Is there some resemblance in academics from high school classes?

Hello, I am an extremely curious first year student, who is hoping to get a summer research position. Earlier on in the year, I had a successful interview with a professor of General Relativity, whose grad lectures I had been attending. By "successful," I mean he said I could join his reading...

Yo, I'm a freshman mechanical engineering major. I applied to 5 summer internships, but I am really not feeling it at all. I think I should start contacting some Profs. at some local universities (including mine) about assisting them with their work this summer. I just want to do something...

Hello, I'm going to fail a first-year university course ( but it's non-math ); how badly is this going to affect my math grad school prospects? Would I still be able to get into good graduate math programs as reasonable possibilities? ( i.e., not under the condition "just get 100% on every...

Analytical definitions vs intuitive (or perhaps "first year") definitions I just began my real analysis course in college and we were given an assignment; a bunch of mathematical terms for us to define. We are asked to define them using two textbooks, one, our first year calculus textbook, the...

As the title says, I'm a first year university student, currently attending Northern Michigan University. I'm really quite unsure about what classes I should take in my second semester and was wondering if anyone had some suggestions. I'm unsure what kind of physics/mathematics I want to get...

Hello there, I am currently 14 and 1 and a half weeks away from starting high school and over my summer break I've developed a strong fascination in theoretical physics, especially in the brane theory(which involves the notion that there are actually 11 dimensions of space and one of time) and I...

So I just completed my first year of Physics at my university. It could have gone a lot better, but I got sick with Crohn's and that really screwed things up. I'm not sure if physics is right for me, so I need input. The thing that makes me really question my self is that all the other physics...

Hi, I am an EE student and I'm nearing the end of my first year from a 3 year course. I am quite sure that I want to continue studying after I obtain my degree, however I'm not sure what I want to study just yet. Is this normal for someone at my stage? Or should I already have a clear picture...

I've heard from a few people that chemistry courses get quite hard when the 2nd year starts. I would have thought since you start to specialize in chemistry there will be a lot of overlap between classes which would make things a bit easier. I was thinking about trying to double major so I can...

"you're in pretty good shape" first year physics textbooks.. Hi, I'm wondering if there were any books for which if you were able to do the problems, then you're in good shape.. For example, if you can problems from Spivak's "Calculus" book as you are in your first year, then you're in pretty...

Is first year math in an university just Calculus I, II (or AP Calculus BC), and III?

I am planning to become a physicist. But here is my question. Next year I will be heading to a post-secondary institution; however, I am unable to decide whether I should go to a college or university. Here are some problems 1. Money isn't a BIG concern, but it's always good to save up...

Hi, I'm going into my first year of university and I'd really like to know about how "ready" one should be before taking a first year rigourous calculus course (Analysis I). My current plan is to take random credits of courses that interest me and wait until next year before I begin taking the...
