I understand (or at least thought I did) :D Kirchhoff's rules. When I got to this circuit; however, I got a wee bit confused. The arrows indicate where I placed my three arbitrary currents. When writing equations for the two smaller loops (the ones on the left), I didn't know which current to...

Guys Rules for Girls! Were you thinking we have not any rule?. These are the ones as far as I am concerned: notation: (Otherwise she would be discarded) means I would never date a girl whose behavior is violating the rule. 1. If you're unhappy with something, say so. Don't expect your...

I'll let you in on the rules girls wish guys knew but wouldn't tell them because they should already know them! 1. Asking a girl on Friday for a date on Saturday is completely unacceptable. Keyword: Planning 2. Shave every day. One day's growth of facial hair is worse than a girl not...

The thread about guys rules for women reminded me of this. They are fond of making rules... From: http://www.yoest.org/dating_my_daughters.html Rule One: If you pull into my driveway and honk you'd better be delivering a package, because you're sure not picking anything up. Rule Two...

Hello: I was having trouble answering these two probability questions, so assistance from anyone would be much appreciated. A project director runs a staff consisting of 6 scientists and 3 lab technicians. Three new projects have to be worked on and the director decides to assign 4 of her...

Q) Given R1=10 Ohms, R2=15 Ohms, R3=5 Ohms, find the current going through each resistor in this pathway in the attached circuit diagram. My solution is as follows.. i'd appreciate it if you guys could verify if its correct or not: I2=I1+I3-------------------------Equation 1 Starting...

This is the title of a book describing how Bush and Blair have been making and breaking their own rules for their own agendas. Part of the book has to do with a January 2003 memo, reported in the New York Times today; you can read about the memo without a subscription, at the BBC report linked...

i mean rules such as demorgan's, material conditional, conditional proof and so forth.

I'm interested in synthesizing complex waveforms using sine waves. I know that when two sine waves which differ slightly in frequency from one another are summed, amplitude modulation (AKA "beating") with a frequency equal to the difference in frequency between the two sine waves ensues. This...

I just want to know if a negative exponent is as just the same as saying one over another number. For example: 5^1/3 = 5^-3 Another thought would base numbers only affect base numbers and exponents only affect exponents?

The ammeter shown in Figure P28.18 reads 2.60 A. Find I1, I2, and E Really confused on how to do these problems...any help would be appreciated...

I know that in order to be helped we must present our thinking, but I cannot do that since my knowledge in this topic is small and I don't have time to make a search because I have to study for my math's test that is tomorrow. I hope you understand. Imagine that you are going to visit a...

My physics class rules. Reasons: 1: It's not a "school-required class", Which means that the speed of learning is adequate for not ripping my hair out in disgust. However, it IS a collegebound-required course, so I still have quite a few potential dropouts. Lucky for me, 5 kids've...

hi, I'm currently doing a mechanics module at Uni. The thing is, I'm not very sure about rules regarding the vector cross product and dot product. For example, it says in my notes for angular momentum: "Introducing polar coordinates \mathbf{r} = r(cos \Phi \mathbf{i} + sin \Phi...

Hey, We recently started learning about magnetic fields and forces in physics and we took these weird right hand rules... After much attempt I cannot, for the life of me, figure them out. Is there any way I can find the direction of the field or a force without using my right hand? Like on...

Hi, I am confused about the electric dipole selection rules. Delta l = +/- 1 Delta m_l = 0, +/- 1 but are there rules for Delta j and Delta m_s and Delta n? Is there a (semi-rigorous) way to conceptually understand selection rules? Thanks.

Hi, I have a question on selection rules for electric dipole transitions. It has to do with a GRE Physics exam question that's confusing a number of students at grephysics.net ... if any of the quantum guru's here would like to help, please check it out at...

What are the Feynman rules for phi to the sixth theory? Can anyone please help? Peskin and Schroeder does phi ^ 4th... I can't help thinking the derivation is the same for phi to the sixth, and that the rules are the same. Could that be correct? Thanks so much for your time, Job...

This was sent to me by my niece. Only blame me if you feel it is absoulutely necessary. :smile: The Guys' Rules: At last a guy has taken the time to write this all down. Finally, the guys' side of the story. (I must admit, it's pretty good.) We always hear"the rules"from...

Is it possible to manipulate and substitute modulos like so a^5 = a (mod 5) a^3 = a (mod 3) a^15 = a (mod 15) By substituting the first into the second?

Yep every one is, i have broken all the rules. Lust, i have done loads of lusting. strike 1 Glutton, well may be a bit, strike 1 Avarice, Hmmm, strike 1 Sloth, i suppose so ...

does anyone know what they include? here is a prefrence. thanks

hiya I understand vectors perfectly, but still something is bothering me when it comes to forces being represented as vectors We'd compute the x component of force F with F*cos(alpha), alpha being angle force has with x axis. Promblem I have with this is why does force follow the same...

Hi I was wondering: How much does it cost to do (legal) genetic experiments involving animals? What's the minimum amount of time/the average of time experiments like that take? Would you have to do something like that at a university with animal facilities, or could you do it other...

This journal will be the journal that follows through my progress in school. I have some big goals this year, and I believe this would be a great way to stay on track. Anyways, I have another journal going too. Check it out if you like at...

http://worldnetdaily.com/news/article.asp?ARTICLE_ID=45874 What are your thoughts about this? I didn't post this in the politics section becaues I think it has some philosophical significance.

How much of it can you eat before you get surrounded by a halo of garlic odour, how much time does it take before the odour starts going through your skin, will a shower clean you enough or is it something that just needs to get out of your system? No, no one complained yet o:), but at times...

Hello. I am in confusion because I cannot understand which formula will be used in this and that derivation,because there are many formulas of physics.Then how we come to know that this specific formula must be used in this derivation It is a great confusion for me. Please solve my problem...

Ok, I've been noticing recently that there seems to be a lot of superficiality in relationships and dating. A while ago, a friend was telling me how with some women, you can be on dodgy ground by saying "you look good in that" because apparently that implies that they don't look good normally...

Hi, I've tottally confused myself over the mutiplying rules. Can someone please tell me all the rules +x+ = -X+ = +X- = -X- = Because I am stupid and keep messing up my polynomials with them. look forward to posting many easy questions for you guys, Dam some of this stuff is...

I came up with three equations, to find three different currents in a DC circuit, using Kirchhoff's loop rule, but when I solved them as a matrix in my calculator the bottom row becomes all zero's and the first two rows do not appear to be in "rref" form. I solved the system of equations by...

Mine are just about GD: 1.you're during a hot discussion with someone and your favorite thread's suddenly closed!because someone doesn't care the rules of PF. 2.Some super mentors are off even when they're on! 3.there is no serious subject for some members like myself and there is no funny...

Attennnnnnnnn... tion! Rule One: If you pull into my driveway and honk you'd better be delivering a package, because you're sure not picking anything up. Rule Two: You do not touch my daughter in front of me. You may glance at her, so long as you do not peer at anything below her...

This ruling makes me very nervous. http://news.yahoo.com/s/ap/20050623/ap_on_go_su_co/scotus_seizing_property_10;_ylt=AjD7WnZAJ_f_VjRE9mHYjPduCM0A;_ylu=X3oDMTBiMW04NW9mBHNlYwMlJVRPUCUl I must admit nothing but pure contempt for developers, mostly because of the power they already have in...

What are the rules for the usage of which and that? I am reading a book that (<- :wink: ) I think is littered with this grammatical error. How should the words be used correctly and are the following sentences wrong? Any variation which is not inherited is unimportant for us. I cannot...

Can you tell me what general rules does antigen have in human immune system ? I assume it is statically floating around in our blood till it is eaten by Tcells. I also just learned it has a specific identity such that Tcells can recognize it, but what is that specific identity ? Second...

Hello Everyone, I am having trouble with the left and right hand rules in Physics. If anyone could explain them to me with as much detail as possible I would really appreciate it. I can tell you what I know and some of what I would like to know if it helps: The left hand is used for...

just a simple question: are perpendicular lines diff from bisector lines? if so, how are their "rules" different?

Using Kirchhoff's rules, calculate the current in R1 with the directions indicated in the figure below. Assume that R1 = 1.00 kΩ, R2 = 3.00 kΩ, R3 = 5.00 kΩ, E1 = 60.0 V, E2 = 50.0 V and E3 = 65.0 V (Diargram in attachment). This problem has kind of stumped me. I tried setting up three...

I have an egg drop design contest. Here are the rules: We have to drop the egg from classroom height (about 6 feet) and from gym height (about 13-15 feet). The capsule cannot weigh more than 550 grams and cannot exceed 7"x7"x7". The egg shell and the yolk have to survive. You are...

I'm only interested in the inference rules. I've read that people use different sets of rules, and I'm trying to find all of those different sets. Here's the ones I have so far (read "/" as a line break): 1. Modus Ponens (M.P.) 2. Modus Tollens (M.T.) 3. Hypothetical Syllogism (H.S.): p ->...

Do you guys know any websites with the COMPLETE list of rules for net ionic equations?

:cry: We found that "tidy function" exists, when wave function intepreted as fi=X(1)X(2)alfa(1)beta(2) for two electrons is antisymetric and fill Pauli rule. But we were unable to find an simple explanation for it. And believe us, none book was able to "show us the door". Thanks for any...

I would like to ask two questions about Hund's rules and L-S coupling: 1. Some textbooks state that when doing L-S coupling and applying Hund's rules, "The maximum values of S and L are subject to the condition that no two electrons may have the same pair of values for m(sub s) and m(sub l)...
