Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg).These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active," "passive" and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion.
Next semester I am transferring out of my community college to a top 50 physics school in the U.S.
Sadly I was off cycle at my college and I did not have a chance to take Multivariable calculus (they only offered it in the fall, and I still needed calc II). I did take Diff eq & linear...
Hey guys,
I am having issues with E&M. I am taking it again this summer and I am scared to death. Last time I took it, I wasn't able to withstand the load and drop out before the deadline. I am very good in Math, but the teachers are horrible.I was able to pass the first test with a horrible...
I received a B.A. in Physics which was essentially pre-engineering. I then went on to study Chemical Engineering. During my first semester I realized that the engineering world was absolutely not for me. I absolutely love Physics however and thought of pursuing more physics education. I...
So here's the story.
I am a 20 years old student about to finish his B.Sc in Physics in Leipzig (I will get my degree this very semester), and the situation which I am facing right now is a bit troublesome for my future. Even though I am getting my bachelor in physics, I want to do my master...

I was experimenting with some physics and the mathematics started to get a bit tougher than what I'm used to. I had a professor who looked at what I'm doing, offered to guide me, and told me to do some research on the variational principle.
At the moment, I am in Calculus II. I did a couple...
I am sort of in an odd situation or at least I think it is odd. Right now I am currently dual enrolled in precalculus and trigonometry. Trig I don't feel is difficult but I am worried that is because my professor is too easy. In short, for trig I don't feel like I am being prepped in the way I...
Hi there, I am currently a secondary school student in the south east of England, and I wish to become a Physicist or Astro-Physicist somewhere along the line in my wonderous future... *hint of sarcasm for wonderous*

Okay so I was recently accepted to Cornell University's Computer Science program (engineering). I plan on becoming a software engineer when I graduate, but am unsure of what path I should take. From what I've seen, only a computer science degree is needed, but I would think that more math would...
A couple of months ago, in-between jobs, I was doing some light research work at Cornell and sitting in on some classes (hiding behind a Big Red hoodie) when a graduate student offhandedly introduced the class to system dynamics and continued rambling on. I knew immediately that that was what I...
Hey guys, I'm a second semester sophomore who goes to a school that's not terribly well known for math. As such, I'll have taken most of the math classes I want to take by senior year (we don't have a very strong graduate program, so not a lot of good grad courses except for applied...
Where shall I begin, I am 19 years old now and I have this very strong desire to study physics, ever since I was introduced to Feynman and Carl Sagan and other famous physicists.
After reading a bit more about the field I was amazed by the sheer variety of interesting fields physics had to offer...
I'm in my spring semester of my sophomore year at college. I was inspired by a speaker who came to my intro to engineering course to try for an internship for an engineering job. He said at the beginning of his sophomore year he did it and it left a great impression on the company that he was a...
Hello, I'm currently 21 years old and have a question regarding a career in physics. I have made it through high school with decent grades, and spent most of my time playing video games, and not focusing a lot on education and not having parents who didn't want to tell me how to live my life and...

Here's 2 simple questions :)
1) Should I take Physics I or Statics first?
2) Should I take them together?
As a side note, I've only taken Calc I and Calc II...I plan on taking Diff Eqs along with the above in the same semester.
Thanks for any opinions on this!

I am having trouble with part of this question:
y'+2y= g(t) where g(t) =1 for 0<t<1 and g(t)= 0 t>1 and y(0)=0
I found y= 1/2 - (1/2 * e^-2t) for 0<t<1 but am having trouble with g(t)= 0.
I know y = Ce^-2t. y(0)=0 doesn't apply here since t>1 correct? Can you point me in the right...

XL/Z2 = (12 + j15)
Current = 11.27 Amps
