Does anyone know where I can find 3 Volt DC Motor Performance Graphs on the web? I'm looking for something like this, but with a 3 Volt motor. My googling has yet to find any relevant results. Thanks in advance.

Hi! I' having a bit of trouble with position-time graphs. I know how to use a velocity-time graph to make a postion time graph, but how can you tell, using velocity-time, if hte object is moving backward (past the point where it began)?

Hi guys, I am doing a lab in physics, which requires me to make d/t and v/a graphs. Our teacher wants the graphs to be nice and smooth with tangent lines and everything, thing is, i don't know what prgram to use. He said no excel because they don't give u smooth lines. Any ideas?... Any help...

I have the AP Calc test coming up in May, and polar graphs are going to be of somewhat importance. The area of a polar region is: A = \frac{1}{2}\int_{a}^{b}r^2d\theta The only thing I don't understand is how to know your bounds. Example: Find the area of one loop of the polar...

Hi I'm doing my physics coursework, and am rather stuck. It's on senors, we have to choose a make a sensor and then use/test it etc - First problem: I'm using a photodiode and, I've put it in parallel with a mulitmeter, reading it's resistance, at different light levels. i have...

If anyone is interested in seeing what a serious effort to catalog UFO sightings looks like, try here: http://www.larryhatch.net/ *U* is a serious 20 year UFO research effort to catalog, map, and do statistics on reports worldwide.... Discovered hoaxes and misidentified mundane events are...

hey everyone, so i kno that the area underneath the lines represent displacement and that the slope of the lines on vt graphs represent acceleration but how do i go about measurign them and actually getting numbers answers? See the question i am trying to answer shows a vt graph and asks me to...

I want to ask you an exam question about sketching graph of a function, please help me; I want you to look at question 2 from the following link especially 2 d)(about asymptotes) http://www.math.metu.edu.tr/WWW/courses/math119/119F0405M2.pdf and the solutions given by the...

The electric potential along the x-axis (in kv) is plotted versus the value of x, (in meters). Evaluate the x-component of the electrical force (in Newtons)on a charge of 5.10 micro-C located on the x-axis at x=2.8 m. http://www.geocities.com/vsage3/p.bmp I tried finding the value of kV...

Is there any software which can help me plot graphs of mathematical functions i dearly need it for calculating areas in definite integral. :shy:

Hi Guys I need some help on graph connectivity problem. Given a graph is connected with probability p, what is the probablity that its subgraph is also connected? In other words, we have to find the probablity that a subgraph of a connected graph is connected? I hope i have made my...

Acceleration/time graphs! Hey all... I'm having tons of trouble with what seems to be an extremely easy question. :mad: The question portrays a toy car...which can move in either direction along a horizontal line (the + position axis) The car is given a large force toward the right of...

i know that acceleration and force are similar and dependent on one another...but are they always the same and are their graphs always identical? or are they just proportional? :frown: Also, anyone know how answer this question: two forces are applied to a cart with two different spring...

Hi, I'm typing up all my maths notes for when I go to university and I have some fairly good programs for displaying all the maths symbols etc. However could someone please point me in the direction of a good program that I could use to quickly make graphs of functions or easily make diagrams to...

Hello everyone. I need help. If there are given 2 graphs in which one of them is the graph of the derivative of the other graph (that graph is the antiderivative - the "original" one), how can I tell the graph of a derivative from a graph of an antiderivative? In another case: the...

Logarithms...i need help. A logarithm of a number is the exponent of the power to which a fixed number. called the base, must be raised to produce the given number. I absolutely do not understand what these things mean. In my textbook it shows a graph of x=10y. Then it follows with 6...

How do I graph parabolas/quadratic equations?

When one sees graphs that are published in research papers and journal articles, all data points have little rods with bars on them protruding from them on either side.. What are these for and how does one interpret them? Thanks

hello Im new to the forum i hope u guys can help :) I was wondering if u can explain these 4 graphs to me: In the attachment thanks. Its about has wing sections. sorry about the rubbish quality of the pic the attachment size is too small. :frown:

I have this maths assignment and the first part I can't do. I've been searching the net for help until I found this site so hopefully you smarties can help me. I was given a dispacement time graph and from it I have to find when velocity was greatest and create a velocity time graph from the...

Ok. Please look at the attachment for the first part, and this web link for the second part. http://www.prenhall.com/divisions/esm/adv/tiponline/rankingtask/files/01KINEMA/kine003.pdf For the first worksheet, this is what I have so far. 1. A 2. D 3. F 4. E 5. B 6. C Is it right, or...

Alrighty, I have a problems with trying to convert graphs into.. well other graphs. Right now I'm sort of stuck on Velocity, Accerleration and Force. For instance covering this statement into a Graph. the object moves away from the origin with a constant velocity. Then I got to graph it as the...

Graphs of a vs. t, v vs. t, and d vs. t ? Plese help ! I am given a graph of a vs. t How do i use it to determine the other graphs: v vs. t d vs. t

What is the definition of a planar graph and which properties does it have ?

Suppose I have a directed graph in Rn. Where the graph is a hypercube, (a square in R2, a cube in R3 etc). Suppose I define an equilibrium point of a directed graph to be a vertex such that I can travel from any adjacent vertex along an edge to that vertex. What is the maximum number of...
