My thoughts exactly. However, I think the problem is that the difference in frequency observed from the emitted is simply not large enough. As the raptor moves towards the person, the frequency should get larger as the raptor increases in velocity, correct? As I've said before, I just don't...

Homework Statement I like to visit reddit. Browsing I found this comic: I'm assuming sea level. Speed of sound: 340.29m/s Homework Equations Wavelength = velocity of wave / frequency change in frequency = -(velocity source - velocity reciever) / wavelength (SOURCE...

Homework Statement I'm having a real hard time on the last homework question for this week for my Uni Physics I course. Here it is: Top-fuel dragsters can accelerate from rest at a rate of about 5g. If this does not sound impressive, consider that for most automobiles the friction between...

I'm no professor but I find solutions to homework problems immensely helpful when learning a new topic. There are some situations where I obtain a correct answer but the reasoning behind my process was faulty. This can be frustrating and lead to the feeling of "well they're just making this...

Wow, if this is indeed true I know exactly what I want to do with my physics degree. Accelerators and all the discoveries made by them are what really got me excited in physics in the first place and I would love to work in a national lab somewhere doing research. Thanks for pointing this out, I...

I think it's natural to forget things you don't use very often or to have the occasional slip-up. I forget negative signs all the time. I'm not sure how often you're using what you mentioned but if it's not very often then I wouldn't worry about it. It's pretty human to have to dust off the...

The single biggest element that helps me get good grades is study habits. I know you said you studied hard, but in my experience how hard I study is not as important as how I actually do the studying. I could spend hours with my textbook going over notes and know enough to just pass an exam but...

Alright, I realize now what I did was incorrect. OrthoP should be = (14, -43, 20)/15, I forgot that there was a -1/3 in ProjP which is why I didn't get 20/15 and added the -2 wrong to 45. However, that's still not what's in the back of the book. Argh. I guess I can take my case to the prof in...

Ah, yes. It should be QQ in the denominator rather than PP. I just translated it incorrectly to the forum, I've been working on this for a while now and am getting frustrated. But if they're using P=5i+2j-k...that's not in the problem. It appears the textbook is incorrect?

Homework Statement Find the projection of P in the direction of Q and the component of P orthogonal to Q. P=i-3j+k Q=-i+2j+5k Homework Equations ProjQ(P)={(P*Q)/(Q*Q)}Q OrthQ(P)=P-ProjQ(P)The Attempt at a Solution First I get P=(1,-3,1) and Q=(-1,2,5) ProjQ(P) =(-2/30)*(-1,2,5)...

I'm a junior now. I'll be graduating in five instead of four years. It sounds like you want to use nanotechnology to do things with neuroscience. It's worth keeping in mind that projects like that will involve a lot of people. You're not going to find someone who has a Ph.D in neuroscience...

I'm currently at a crossroads myself. I recently changed majors from chemistry to physics. 2nd year chemistry is quite a step up from first year general chem. Sophomore year is when you usually take Organic Chemistry along with the rest of a calculus sequence, and the science major's physics...

Summer 2010: 1st Half Calc I General Chemistry II 2nd Half CalcII European Politics Fall 2010: University Physics I (physics majors section) + Lab Intro Astronomy + Lab (Really excited about this one, even though it probably won't be too difficult. I've been interested in astronomy...

What Newtime said. It's doable. What you said minus the Modern Physics is what a 2nd year chem major would take at my school. It's a lot of work but if you don't get behind you should be alright.

This is mostly because a MS is becoming standard for most jobs in science and engineering. I plan on getting a MS in physics and my adviser told me that it would be advantageous to me if I could stay another semester or so and complete some of the very upper level physics courses before moving...
