Capillaries? Sorry about my whining last night, Evo, I was having a bad night. I won't bore you guys with the details. Is there a link where I could learn how to utilize these features. If I want to mark a quote where the OP is featured, the only way I can do it is quote the whole post...

I think I may have just phrased what I meant poorly but.. If I take any linear DE, consider the independent variable (t) to be some constant, and consider y and all its derivatives to be just standard variables, and I graph this function, it always is a linear object (line, plane, etc) with...

I was talking to my physics teacher today about electric motors and used some information I learned here. I'm not calling you guys wrong by any means, I just would like to know what is real. He claimed two things: 1. As load on an electric motor goes up, current goes down (I know this is wrong...

Hi every body I'm a french teacher, teaching physics and chemistry in a french middleschool I'm trying to teach sometimes physics and chemistry into english but I would like some help from teachers to find some practicles and investigations . and sometimes to translate some words ...

I am not a teacher or even student of physics but I am translating a physics paper into English and I need some help. I have a sentence that may translate as follows: "Newton introduced m-dependency upon taking into consideration, within the context of his second law, the experimental fact...

Hello! I'm not sure if this was the right subforum to ask this question, but I figured I'd give it a shot anyway. Currently, I'm a student at a California CC looking to transfer to a CSU here. I'm majoring in physics and have knocked out all my lower division classes and will be...

I am SO annoyed with this problem. Ready to jump out a window. Homework Statement Find the first three terms of the Fourier series that approximates f(θ) = tan(θ) from θ = -π/2 to π/2. The Attempt at a Solution So, I know that for an equation on [\frac{-b}{2}, \frac{b}{2}], to...

Hello, I think this is my first post here, but I've lurked for quite a while as a silent user and even before then as a non-user. I'm currently enrolled and majoring in pre-engineering at a community college in Mississippi. So far, I've taken Algebra, Trig, and calculus 1, and I'm...

Hiya folks, In an effort to get the students in my Advanced Physics class to rely less on calculators and to develop their math skills, I am going to give them the option of using slide rules this year. I am offering them a small bonus on tests if they use slide rules instead of calculators...

Homework Statement An electron travels 1.68 m in 6.74 × 10−8 s. How fast is it traveling? Answer in units of m/sHomework Equations The Attempt at a Solution (1.68)/ (6.74 x 10 ^ -8) = 24925816.02 i asked the teacher on this education facebook thingy for our school called edmodo if i was...

Okay so I started my first calculus based physics class, the first day I realize he has a very bad accent but I feel like I might be able to understand him. The second day we really start getting into vectors, magnitude, cross product, dot product, etc, I'm sure the supposedly really easy...

Ok so my teacher has recently covered this chapter, but one of the concepts that has been bugging me for ages. Fr an object to experience zero acceleration, the forces acting on it have to be balanced. That means tha applied force has to equal the frictional force so that the resultant force...

I just had arguments with my teacher about my test answer in class. I'm a little upset, but maybe I'm acting like a spoilt brat (I'll be the first to admit it) I went out and I'm using a hallway computer in my college so I can't post images. I still disagree with him-- But I'll try to explain it...

Z diagram and Q cycle ?? (Bad teacher) Hey guys, my teacher told me to review the Z diagram + Q cycle. I'm pretty sure that this means I'm to study Light reactions of Photo synthesis and The Fluid mosiac model. Sound Right? Also this is my first post, so hi :D

I'll explain the problem in a nutshell. 2% of brand X tires are faulty, 98% aren't. If you take a car with 4 brand X tires, what is the probability that 3 of them are faulty? My work: (.02^3 * .98) * 4 = 0.003136% However, my teacher thought it was just: (.02^3 * .98) = 0.000784% I believe...

I've posted here before about how I dislike my physics teacher for various reasons. He ignores kids' questions, and he mostly talks about sports, or makes pop culture references and jokes just to get laughs from the class. No one thinks he is a good teacher, and he focuses more on his football...

Hello, this doesn't seem to quite fit into any of the forums, but I'm hoping to find some help. I want to set up a website as a teacher for my students to look at. I'd like to - Post general interest stuff - Post solved homework and tests - Let the students log on to do the above and most...

Homework Statement These are from a british columbia provincial exam from a few years ago. My teacher enlisted my help in trying to figure out a solution. This is supposed to be for physics 11. I can't figure it out. Maybe one of you awesome people can help me. Thanks... Question1. A...

I am a public school teacher and make 50k living in Houston. Last year I earned an award for best teacher at my school, but I want to do something more challenging. I just got accepted to the engineering program at University of Houston. I will be pursuing my second bachelor's degree. 1)...

not sure that this was the right move in a 3rd-grade class... :rolleyes: https://www.youtube.com/watch?v=ZPHOgUOIc1A

I was at my school's tutoring center and heard these two guys agreeing on how math teachers make a huge difference on how well you're going to do in whatever math class you're taking. Do you agree or disagree?

Okay, so our teacher gave us to define s=vt. Now i did it like that: s=vt=(v_0+at)t=v_0 t+at[SUP]2[SUP], but then, teacher said that's wrong, it should give you s=v_0 t+ \frac{1}{2} at[SUP]2[SUP] Who is wrong me or teacher, If I am wrong, tell me where is my mistake, if the teacher is wrong let...

In class, she said "there's no way of definitively knowing if the universal law of gravity will remain valid in 10 000 years. Science is therefore dependant on the probabilistic nature of its findings by assuming them to be definite." What do you think of her statement? This is my first...

Hi, I've spent the past year or two doing a lot of "soul searching" (if there is such a thing, *laughs*) and along the way, I learned a lot about science education and employment in general. What I've learned is a lot of who I've been through most of my life was predetermined before I was even...

Homework Statement Problem is in the picture Homework Equations The teacher told us the Fnetx = 20N - Fx (Fx is 0) Fnety = Fy - 50N (Fy = +25N) The Attempt at a Solution My answer was 32N. But my teacher said the answer was C. which was 77.5N. He got it because Fnety = 75N for...

1. Homework Statement This is a relatively simple problem in classical mechanics, but my attempt at a solution seems to conflict with the result my teacher announced. The problem is as follows: A homogeneous cylinder with mass M and radius R lies at rest on a plank. The plank is then...

I've recently had a revelation in my life that has filled me with desire to become a teacher. ***I apologized for the life story, my questions come in the very last paragraph.*** When I was in high school I never had any direction or any idea of what I wanted to do with my life until my...

My teacher says : C language programs are portable on all platforms, which includes, Unix, Linux, windows etc. My question : What is the difference between C language programs and Java language programs when all the programs of either languages can be run on any platforms? My teacher says: C...

I am a senior taking AP Calculus. I want this teacher to give me the ''outsanding math student'' award at the end of the year but i think i just ruined it today. During window i was finishing a social studies thing, that was just before the Calculus block. So i didn't go because i was doing...

I'm brand-new to this site, an English teacher, certainly not a physicist, but I'd sure appreciate some (gentle) help. The short version of my question: How can the universe expand into infinite space? Are there two kinds of space? The first is the distances between galaxies in our...

If I was in a bio class, I wouldn't even complain. But physics? My teacher does not teach why things work, just throw random formulae and show how to 'plug-in' values. I know one must learn a skill to deal with this type of teacher but I have never had this kind before. How did you cope with...

I'm currently a weather forecaster for the US Air Force with my Community College of The Air Force Degree (equal to an associates) in Weather Technology. I would like to use my current knowledge to become an Earth Science teacher for grades 7-12. I currently live in Tucson, AZ and right now can...

Hi all, Im an EE major and am getting ready to pick spring classes tomorrow. My only option for Calc 3 which will fit into my schedule seems to be the easiest professor possible (aka they give over 30% A's, which I found from the rating website, I have also heard from other students that it is...

I remember my teacher saying that anti-lock brakes worked better because of the static friction coeffiecient was higher than the kinetic friction, but i never understood why. Is it beacuse when you stab the brakes their is a larger impulse?

hi Our teacher told us the following: F = m * v² / r = m * 4 pi² / T² * r = m * 4 pi² / k * 1 / r² = c * m / r² F = y * mM / r2 Why is there the k and 1 / r² and later the c?

How can they be equal at that point? And where is the force that the string applies. By the way Fk = Buoyancy Force

I've been set the task of determining whether or not using alternative fuel sources will "fix" anthropogenic warming. The teacher's argument is that it is not so much the CO2 output of energy production methods, rather output of waste heat. We are to compare the efficiency of waste heat produced...

Homework Statement This problem was given as extra credit to our class. My teacher was unable to solve this problem. She had asked several math teachers as well as both my parents who are electricalmengineers and commonly use math. This is the exact wording of the problem. In the 1964...

Homework Statement I'm not able to understand this misconception "An observer can see more of their image by moving further back from the mirror" Homework Equations The Attempt at a Solution I tested and I believe I can see more of the image as I move further back from the...

And what were they like?

Shame on me for giggling at this. :redface: http://www.daytondailynews.com/news/dayton-news/kettering-teacher-suspended-for-allegedly-calling-students-names-1221364.html

I've been applying to work at various high schools in California and hoping to get a temporary permit because I'm not actually certificated. This makes me wonder something, however, especially considering that thread that came up about why the US educational system sucks. What does one need...

my teacher asked Explain why it is necessary to standardize your EDTA solution. I am not totally sure why it is important.. can some one explain?

Hello, I will be beginning my first year of university in the upcoming September, where I am enrolled in Concurrent Teacher Education/Science-Mathematics (in essence, it is a 5-year program, 4 of which is a B.A. or B.Sc. and 1 is the B.Ed. [teacher's college]). So, I am preparing my timetable...
