    Looking for a good workbook or website

    Hello f(r)iends! I'm a first year undergraduate physics major, in my first electricity and magnetism class, and I feel like I need more practice than what is assigned in the online homework. If you could recommend a good workbook with lots of exercises and if possible solutions (not just...

    Pick my class for me!

    I suppose it's programming for me! If I can somehow make time for it I'll try to fit the Chemistry and Astronomy courses in, but the programming class will take priority. Thanks!

    Pick my class for me!

    While I'm not so indecisive as to completely let others pick my class for me, I would like your 2 cents on the matter of what I should take. So I have to take one lab science outside of my major (physics), and I have narrowed it down to three: programming for scientists/engineers, chemistry (the...

    Electricity and Magnetism Book

    Thank you for your reply, Bob S. However, I think you may have misunderstood my question. It is not the case that I am having trouble with the units for quantities. Indeed, both of the textbooks I cited use the MKS system (though I don't have trouble with CGS, either). I have to take the lab...

    Electricity and Magnetism Book

    I'm a first year undergraduate taking my first electricity and magnetism class, and going through all the classic material: Coulomb's law, electric fields, flux, capacitors, etc. And the book I have explains the material relatively well, but I feel like I'm missing out on so much by just being...

    Integral trouble

    Homework Statement \inte^{2x}cos(x)dx Homework Equations The Attempt at a Solution This isn't exactly a homework question, but it's close enough: it's from my old Calculus book (Larson), and I've been stuck on it for awhile. I just need a little hint or something. I've tried a...

    The Limit of Moore's Law

    While there are various estimates to the year in which we will not be able to continue adding transistors to a given area on a silicon chip, the typical guess is between 2013 and 2018 [1]. Given that there will eventually be a limit to how small we can make the transistor (due to quantum...

    Spheres on the GRE

    "Two small spheres of putty, A and B, of mass M and 3M, respectively, hang from the ceiling on strings of equal length l. Sphere A is drawn aside so that it is raised to a height h0 and then released. Sphere A collides with sphere B; they stick together and swing to a maximum height h equal to "...

    Related rates problem (involving a cone)

    Homework Statement Gravel is being dumped from a conveyor belt at a rate of 30 cubic feet per minute. It forms a pile in the shape of a right circular cone whose base diameter and height are always the same. The height of the pile is increasing at a rate of ____ feet per minute when the pile is...

    How to become an atheist?

    When I became an atheist I was fairly scared of telling my parents. We didn't go to church often, but the beliefs my parents held were very strong, and I knew when I told them it wouldn't go over very well. It didn't. There was a bit of screaming, some teeth gnashing, some silent treatment, etc...

    This picture first made me laugh then think

    No, I skipped 2 and quoted the definitions of philosophy which directly had the keyword 'belief' in them. If not posting a definition is "hiding" that definition, then you hid results 4 to infinity from me. EDIT: Further, even if I was hiding a definition, I gave you two other perfectly valid...

    Moon landing was true - how do i always win this debate?

    What motivation do moon-hoaxers have for not accepting the moon landing? I can see creationists/ID proponents rejecting evolution or the age of Earth because it conflicts with their literal interpretation of whatever creation myths they hold, but I don't understand the angle the moon-hoaxers...

    This picture first made me laugh then think

    Why? You're going to have to define free will before you make that assertion. Also, as a http://en.wikipedia.org/wiki/Compatibilism_and_incompatibilism" [Broken], I probably already reject your assertion. This thread is headed for the Philosophy forums.

    Why do Jupiter's moons line up?

    What are the gravitational factors that nudge the the planets into equatorial orbits? Why aren't the moon's rotation around the planet, say, perpendicular to the equatorial plane? Would the Sun's gravitational pull on the moon of a planet be one of these nudging effects?

    Why do Jupiter's moons line up?

    So I took my telescope out last night and got to actually, really see Jupiter for the first time and it was amazing! While I was looking at it I could see it has 4 moons (though I later found out it has way more than that, but the ones I observed were the big Galilean moons). Another thing I...

    Hooke's Law - System of Springs

    How about it? Do you have a question? Showing us pretty graphs doesn't tell anyone what you're stuck on. Also, those bold sentences are there for a reason: use them. State the question, give the relevant equations, and show your attempt at a solution, and then maybe I can give you a hint (or...

    Forces In Equilibrium

    Rotate your axis so that the F1 and F3 are exclusively in the x plane. From there it should be easy. You know the force of gravity, and you can find it's i and j components and solve for the rest. That's the trick to these inclined plane problems -- choose your axis wisely.

    Finding the instantaneous velocity

    The a stands for acceleration, t for time and v_0 for initial velocity, but from the looks of your graph, it's irrelevant. Anyway... Your answer to Q1 isn't quite right. The instantaneous velocity at any time is the slope of the tangent line at that time. It seems you only have a (rather...

    Refund on that last 2 minutes of my life?

    Weighing the languages

    So I just graduated from high school and am heading to college with the intention of getting a BS in physics. I took a semester of programming in Pascal my senior year, but had to drop the class the second semester (to get a freakin' art credit to graduate. God**** arts...), so I didn't learn...
