hey guys, I am a lil confused with this one, not really with the concept, just how to start... 4) a snowmobile is being driven across a frozen lake. Vector V1 and Vector V2 in the diagram represents its velocity at two instants 3 s apart. 1 cm = 5 m/s Determine \overrightarrow{\Delta V} and...

No its not homework, but my teacher (pre-cal) couldn't figure it out and neither can I, so see if you can! I can't draw it so i'll explain it, pretty simple. You have a square (ABCD) with a random point closest to the bottom-left corner of the square (it doesn't really matter which...

hi there i have a question about my math teacher and i bet someone on this fourum could help my teacher is a very tiny person, she's about 4-5 feet tall and one of the nicest people i know she also has a lot of disorders that are all triggered by stress after many years teaching, she has...

Hi, I thought its better to ask you so i am doing it. We have an Physics Professor and he is Old ,around 70 years of age.He is taking half of our Physics's Electrodynamics Course. Let me tell you about him. He speaks very fast and loud and clear.It looks like being so old he possesses lots...

Math teacher in over his head :) Not so much "over my head" as I don't have as much time as I'd like to research the answers. My 7th grade honors class is doing a project on "How fast is the Space Shuttle in terms of Mach?" (My title, not theirs :) ). They didn't have too much trouble...

2(x-5)-(3x+3)<x-7 2x-10--3x-3<x-7 -1x-13<x-7 0<6 i can't find the rules for when the sign changes my son is convinced that if you only divide then the sign changes to > i don't remember and he of course has his book in school :mad:

http://www.telegraaf.nl/buitenland/18899111/Tiener_krijgt_levenslang_voor_verkrachting.html A thirteen year old british boy was sentence to a life-long prison sentence, after.. listen to this.. he (at the age of 12) had raped his teacher in a center for problem children and had stolen her...

I just got done taking a test, and one question really was bothering me. My teacher had one problem where there was 20 m/s^2, this is one signifigant digit? Right? :mad: Yet last time I gave my answer in one signifigant figure, I got a lecture and told he'ld let me get away with it this time...

My physics teacher has posted log questions (for fun/frustration)almost every day. Having last had logs about 8 years ago, i have no clue how to solve for any of them. And seeing as how we don't actually use them in class, he won't help us figure them out. :bugeye: If anyone can offer me some...

\\x-\frac {x}{1}=\frac{12}{25} ...then...\\x-x=\frac{12}{25}\\ ...then...0=\frac{12}{25} ... I hope not... Is there a way? It was on homework and he says that all of them have answers. He didnt direct any comment on this problem. btw, only the first part is actaully on the problem...

Find the value of x. Show all work with justifications.

You can't love humanity and love children. For children are an apish mockery of humanity. - Soph Math Teacher Haha, and just for good measure a funny thing this guy in my Freshman math class said. Scene: rectangular table seating 15 of us, teacher at the head of the table. teacher: Mr...

We're doing a science project, and we get major extra credit if we have a question in our project that he can't answer. He told us that his ''weakness'' would have to be physics. So does anyone have some questions i could ask that could stump an eighth frade science teacher? Anything at all...

Hi, my name is Julie, and I have an awful physics teacher. Now, I know that you are going "No, you just don't understand the way he teachers, " blah, blah blah. Ok, no. I am a nerd, right? Right. I keep track of everything that goes wrong, every insult, everything. And add them up. His list is...

alright the deal is my teacher is from baha california. you know the place that is in mexico but california claims it? newayz i can't understand a word he says so i end up trying to do the problems by myself and I'm currently failing because of that. so I'm wondering if you have any suggestions...

Is there any teacher here that teachers Calculus BC?

Right. Here I go. A school teacher sits four pupils around a table so that two are facing another two. The pupils are not allowed to look side-ways. The school teacher has a bag of hats (4 are black and 3 are white). He blindfolds the pupils and randomly places hats on the pupils heads...

Design a sequential circuit to decode a given serial sequence of bits. This is basically a state machine problem. When the given sequence occurs a LED is turned on. 11011001. So there is an input to this problem?

Just thinking about this a bit and I wondered what other stories we may have. For me, it was my high school physics and computer science teacher - my senior year. Until then [and until we left the gang-bangers of SCal and moved to Northern California] I was only in class because I had been...

A certain teacher at my school who teaches compters always says "Magnetism is the future". He says that by utilizing the magnetic fields of planets as "energy boosts or a trampoline" for travel at c+. I explained this is impossible, according to SR a while back, but I backed off (because he was...

A. You are trying to open a door that is stuck by pulling on the doorknob in a direction perpendicular to the door. If instead you tie a rope to the doorknob and then pull with the same force, is the torque you exert increased? 1.yes 2.no A.. The answer is 2. The moment arm is not...

I need help. I'm studying physics, electricity and magnetism. I'm completely lost. My teacher does nothing for me, I have learned absolutely nothing from her since the course began. What I have learned, I have learned from doing homework problems and inferring from those who help me here...

I need to prove to my teacher that i know how to use physics forums, so can i get a response?:smile:

he gave me an assignment about Pendulums and Harmonic motion. He gave us notes on vocab words we would need to know like; Bob, Equilibrium, period, frequency, and oscilation. he also told us that Period is unaffected by height of drop. That Length is directly proportional to Period. and Length...

My Physics teacher wanted me to understand how to derive a=v^2/r using the equations v=d/t, \omega=\theta/t and arc length=r\theta but when it came down to it, i had brain freeze..and when my teacher looked at it, he had brain freeze. This isn't part of my syllabus but i was wondering how you...

there is this scientist in front of a black board. and there is this picture with four e's and a 4 arrows and a squiggly line. i would really appreciate it if some 1 helped me! thank you very much. i tried to draw that picture. it is in this web page . but it is in the "science question"...

This might sound like a stupid question, but in my physics class we have a game called "Will it float?" It's just like on the tonight show. We pick out random things to put in the water and guess if they'll float or not. My teacher decided to let us try to stump her after several weeks of her...

teacher told me that electricity could be defined as "a flow of electrons" When I was much younger, my teacher told me that electricity could be defined as "a flow of electrons". So when I turn on a light bulb or television set, what is actually happening inside? What is making the electrons...

Have some problems with thevenin (or my teacher is wrong, which i believe :)). http://www.fmf.nl/~wim/studie/cir1.png example from my book: Vi=15V, R1=6, R2=R3=3 Voc = Vi R2/(R1+R2) = 5 V (potential divider) R2//R3=1.5 Ohm R1+(R2//R3)=7.5 Ohm --> I = 15/7.5 = 2 A Cause R2 and...
