Hi, I'm interested in how light and how electricity works so I'm interested in a beginners (undergraduate level) physics book that has the following: Giving intuition by showing each experimental setup - visually (with ppictures) and mathematically - which contributed to the understanding...

I'm studying using the popular Lindenberg book. It suggest I have to memorize about 30 elements and their respective oxidation numbers. However, the book was written before they revamped the exam. Anyone know if I still have to memorize this?

Hello everyone. I have a rather unusual issue in which I do not seem to some know/understand basic concepts in prealgebra, but do rather well in something like calculus. By basic concepts, I don't mean something like solving equations, but I don't understand why certain things work the way they...

Find the phase angle between i_1= - 4 sin(377t+55) and i_2= 5 cos(377t-65) The Attempt at a Solution Ok, so I converted i_1= 4 cos(377t+145) and i_2=5cos(377t-65) According to lectures in class the 'most' negative leads. So in this case i_2 leads by -65-145=210. However, if you look at the...

I've been reading up on gauge theory and it isn't easy. Can someone give me an easy summary of its fundamental scope and postulates without too much math. It seems really important insofar as it defines itself as something of a "parent" theory to most of the leading cosmological models of the...

Homework Statement We say that the displacement of a particle is a vector quantity. Our best justification for this assertion is: A. displacement can be specified by a magnitude and a direction B. operating with displacements according to the rules for manipulating vectors leads to results...

I'm trying to get a basic understanding of RF DAC. If I have a DAC that does 100 MS/s with an 8 bit resolution, this translates to a 800 Mbps throughput. Or is this too simple? Now, how does the bandwith of a channel affect this? Say I have two 5 MHz channels. With two channels there...

http://oyc.yale.edu/physics/phys-200 http://oyc.yale.edu/physics/phys-201 I'm starting college in September and have never taken Physics before, so I am preparing by reading different books and watching some videos, and was wondering if this course is worth watching because the curriculum...

The question I am looking at has a man of X kilograms of mass, with a rope tied around his waist. That rope is thrown over a tree limb. The man pulls on the other end of the rope to hoist himself up, with say, Y netwons of force (tension). The aim of the problem is to solve for his acceleration...

The best understanding I have got is that it is the word we use to describe flux - a fundamental state of the universe. Maybe the question can be rephrased as 'why do things affect each other?'

My class wants the 8th edition. Is there much of a difference between the older/cheaper versions? I really don't want to spend a lot of $$ if I don't have to!

So before I graduated with my BS in Civil Engineering I took the FE exam in Arizona and passed it. I then went out of state for my Masters in Civil Engineering. I am getting close to graduating and am looking to get a job. Do I need to retake the FE exam if I work outside of Arizona...

Hi, I have this quite basic question regarding photonic crystals. As I understand, a periodic dielectric structure (photonic crystal) has modes (spatial profiles) at discrete frequencies from: \nabla \times \Big( \frac{1}{\epsilon(r)}\nabla \times H(r) \Big) = \frac{\omega^2}{c^2} H(r)...

I'm taking Physics this year. The problem is that the lectures are not going to be in English, my native tongue, and I'm not yet fluent in the language of instruction. I'm an international student and will be dealing with this my entire studies. The book the class is using is Fundamentals...

Why is gravity considered a fundamental force and not the production of electromagnetism and weak/strong nuclear forces?

Hello Everyone, Recently, I was trying to explain the fundamentals of thermal radiation to a non-engineer and I discovered that I myself have a poor understanding of it. I understand that "thermal radiation is continuously emitted by all matter whose temperature is above absolute...
