Homework Statement Homework Equations E = -dV/dx ?The Attempt at a Solution not really sure how to do this problem. I think I understand E field is negative of slope of V/x, but I'm getting it wrong. just looking at it, I see V=-2 at x=7.5. so the E field to right of x= 5 is y2-y1/x2-x1=...

For a car with constant power, how will its velocity change over time? Since power (P) is the derivative of the kinetic energy (Ek), I've found that the equation for the velocity as a function of time is √(2*P*t/m). Is this correct? Would the graph then be a root graph?

Homework Statement Homework Equations ω=ω0+αt θ=θ0+ω0t+12αt2 I think? The Attempt at a Solution For part a, I know that from the graph, the angular velocity in this case would be constant since the graph illustrates a position in rad vs time graph. The thing is, I'm really sure on how to...

When I am given a function quadratic, square-root and inverse variation I am often uncertain as to how to select my points to graph the function. Usually I can find my vertex easily enough and y and x intercepts if any but otherwise I don't know how to select my points. Are there base points for...

The diagram shows how a force along the x-axis varies with location. A block of mass 7.20 kg moves along the x-axis on a horizontal frictionless surface, influenced by this force. (Graph is attached) A) How much work is done by the force as the block moves from the origin to 8.0 m? B) If the...

I want to create graphs where each vertex has three edges, and is connected by these three edges to three distinct vertices. I'd like to know the number of vertices for which this is possible. By playing around a bit, I've found that it's possible for graphs with 4, 8, and 12 vertices. If v is...

when we throw an object upwards its accelaration is negative and after it reaches the maximum height it comes back to us and during that period it has its accelaration still pointing toward the earth. so does that mean that when we draw a accn time graph, for a body thrown up reaching maximum...

Homework Statement Proper way to graph xy = 1 for a Cylindrical Shell problems. Homework Equations V = ∫^b_a 2πy f(y) dy The Attempt at a Solution I am rotating around the x-axis, so I am integrating with respect to y, but should I choose x = 1/y, or y = 1/x to solve my problem? How are...

There is this graph: http://i.imgur.com/BdwhN3b.jpg where the equation of the function must be determined. Down below is some thinking I've done, where I've found that the oblique asymptote is -0.5x+2, and the v-asymptote=6. I know how to solve something similar with 2 x-int's, but I'm having...

Homework Statement The title, and assume that t=0, x=0 and v=0. Homework Equations Kinematic equations, and area of triangle and rectangle. The Attempt at a Solution I see what I did wrong with the part that is circled "parabola", as it should be just a straight line, but I am lost as to...

Homework Statement Not too necessary to follow this format, but here is my question: I know I probably shouldn't ask such a simple question, but how do I find a velocity-time graph from a position-time graph? I know it's just slope, but I'm looking at a curve, and I don't want to differentiate...

I've been asked to investigate the value of g. My graph shows that the gradient is around 4.4 as when the length was 0.27m, the squared time period was 1.18s (since this is a T2 against L graph). My question is, of course, why? If I am detecting g, which is 9.81 on earth, why did I get such...

Is there an application to graph plots then download or copy the image?Thanks, Tim

The speed is a constant of 20m/s for 100m (moving on a straight line) after 100m, the car stops at a constant 6m/s/s. *So in this case, speed is equal to velocity? *How do you graph velocity vs time graph and acceleration vs time graph?

graph the elliptic paraboloid $4x^2+y^2-z=0$. find four distinct points on the graph this is the graph. do i just find four random points now that lay on it?

In a late 1980s trade journal, I saw a full-page of polar balance diagrams for each major engine type. For each engine type (V6, V8, inline 6, inline 4, V12, etc) a circular polar chart was presented with overlaid color-coded graphs showing 1st, 2nd and 3rd order balance for 360 degrees of...

My physics lab is using a Motion Detector, to measure the time it takes for a high frequency pulse to travel from the detector to an object and back. I have several questions about Velocity vs Time: What does a horizontal line (with 0 velocity) mean? Does that mean to walk backwards, walk...

What does a vertical line graph pointing straight up mean? Same for down? What does a horizontal line mean? y axis=velocity (m/s) x axis=time (s)

Homework Statement A 1-kg standard cart collides with a cart A of unknown inertia. Both carts appear to be rolling with significant wheel friction because their velocities change with time as shown in. What is the mass of cart A? The graph below should be used to solve for the mass...

So this looks really easy, but I can't get the right answer. It asks you to find the minimum acceleration from the graph: http://s22.postimg.org/f5dutd5ap/pic.png. This is of course the point where the slope is the smallest, and this is from t = 3-4 s or t = 4-5 s, depending on whether you want...

I'm not sure how to draw the graph for this question. Could someone please point me in the right direction? I'm also not really sure how you'd find the parent function for the situation. Here's the question: 1) Each of the following situations involve a parent function whose graph has been...

Hi, so after doing some calculus for projectile motion with air resistance, I obtained two equations of vx(t) and vy(t) that describes the vertical and horizontal motion of the projectile. Please tell me if I'm wrong, but I believe since both vx and vy are functions of t, can't they be...

Hi What is the face chromatic number for the Graph Below? Thank You

In the picture below, the "abcdbea" trail is a dominating trail in the graph. My question is that the "agcdbea" is also a dominating trail or NOT? If not why? Thank you ;)

Homework Statement TASK So I have this task with opamp and I have Uinput Sine Graph, now I have to calculate Uoutput and write it as sine function and draw the sine graph. I know that this is an inverting OPAMP which means that output signal will be inverted, so I just have to flip this...

Homework Statement For example, a linear plot would with x and y values would just plot normally where x and y increases linearly from 0 to infinity. When we use a log graph, do we just plug in x and y to a graph in which the x and y go from 0, 10, 100, 1000, or do we convert the numbers...

Hello, I drew up this graph to try and understand the concept of depth-first search. Starting at node C, I was wondering if its correct for the order to be C-A-B-D or C-B-A-D? It seems like you can traverse in either direction without a problem.

http://ypelletier.wordans.ca/t-shirt/feynman-gildan-homme-man-81965 Is this just a cool design or is it a real physics expression (or something that makes sense)? I figure it might be something like velocity is converted to work and "e-," and work plus "n" equals pressure, or something...

Homework Statement Hi everybody. I just started grade 11 physics, and I'm having some serious trouble translating P-T graphs to V-T graphs. I really just can't seem to grasp the concept of this. It also doesn't help that I'm doing an online course and we're not being taught anything. The...

Hi All, Thank you for taking your time to look at my question. I am a web developer and have created a online system that produces graphs but cannot understand how the line of best fit (trend line) is calculated. On paper its easy, just draw it with your hand in between the two lines. But I...

Homework Statement Hi. For this assignment, I was told to create a V-T graph with my own values (this doesn't have to make sense in the real world). The assignment says that a ball rolls on the floor, up a ramp, back down the ramp, and backwards along the floor. Here is the diagram...

In terms of calculus, How do i prove that the area under the acceleration time graph gives me the change in KE / mass... Attempt at solution... Area under the graph of a function y = f(x) is given by ∫y dx Therefore area under acceleration displacement graph is ∫a ds (considering the...

I've been doing some light reading on Geometric Graph Theory, and it seem interesting to me. However, at the moment I've only managed to find a few Wikipedia articles and one .PDF of lecture notes. I'm looking for something which is more complete, such as a book or a website for example...

How would one construct a graph, like the Petersen graph, in LaTeX? Is there a good package to use for it? Edit: I should mention that I'm having trouble using instructions (which are not always consistent) that I'm finding on Google.
