This is a quick multiple choice question in which I need to interpret the graph and see which statement is true This is what I have found from looking at the graph I know that strength is determined by the maximum stress a material can withstand in its elastic region. And toughness is the...

are the points where the derivative is undefined ##x=-4,-2,0, 4##?

My answers: a) At points d the instantaneous velocity should be greatest since slope of c-d is greatest I think b) At point e and g instantaneous velocity is 0 c) at points b, c, and f instantaneous velocity is negative. Could you please verify my answers?

Hi guys, I hope everyone is safe and well. I'm currently nearing the end of my third year dissertation, and I'm looking at analysing pitching moment coefficient (CM) data over a full range of angles of attack for airfoils with different serrations on the trailing edge. What are things to look...

Hey guys, so recently I've been trying to use mathematica to plot graphs for my scientific papers, and I've been starting to wonder - what plot options do you guys use? How do you plot your graphs in mathematica such that they look presentable in a scientific paper?

My attempt, pictorially it looks like I am confused with the questions (a). Does the positron emerge from the field at x =0? There is no potential at x=0, so the positron will continue with the same speed hence its motion is not reversed. For the (b). The maximum volt is 200V, if i apply the...

Hello guys! I just started to learn Special Relativity though a Stanford youtube channel, and I had some problems already in the first class :oops: The teacher drew a graph with one spatial dimension (x-axis) and one temporal dimension (t-axis). Where X is the horizontal axis, T is the vertical...

I am trying to calculate Young's Modulus on the graph below. I have run the test through some software, now want to calculate Young's Modulus to ensure my analysis can be relied upon to be scientifically sound. This is what i have calculated from learning online. Is this correct? I have 2 more...

Hello! :smile: I am locked in an exercise. I must find (and graph) the complex numbers that verify the equation: ##z^2=\bar z^2 ## If ##z=x+iy## then: ##(x+iy)^2=(x-iy)^2 ## and operating and simplifying, ##4.x.yi=0 ## and here I don't know how to continue... can you help me with ideas? thanks!

Problem: Suppose that the function $p : N \rightarrow [0, 1]$ satisfies $p >> n^{-1}ln(n)$ (i.e. $n^{-1}ln(n) = o(p)$). (a) Prove that as $n \rightarrow \infty$, the random graph $G(n, p)$ has minimum degree at least $\frac{np}{2}$ almost surely. Idea: Look at the degree of each individual...

Is the graph Hamilton and Eulerian? The website says the graph is Hamilton and Eulerian but I think it's wrong. Ref: https://scanftree.com/Graph-Theory/Eulerian-and-Hamiltonian-Graphs There is no path that covers all paths only once. Any help? I think the graph is drawn wrongly.

I am doing an investigation of how much a beam sags, based on the distance from its midpoint. This is my hypothetical equation: The relationship between distance, d and sag, s is not a linear relationship. Below, is the determined relationship between the variables, linearized by natural...

Why work done is area enclosed by graph of F v/s x on x Axis but not y axis. Suppose we apply a force on object which is proportional to displacement as ##\vec f##=## \vec x##²then area enclosed by Force and displacement on x Axis is integral of ##\vec x##²but on y-axis it should be integral of...

Let $n$ be a positive integer, and let $G$ be a random graph from $G(n, 1/2)$. Let $e_1, . . . , e_{n \choose 2}$ be the possible edges on the vertex set ${1, . . . , n}$, and for each $i$, let $A_i$ be the event that $e_i ∈ E(G)$. Prove that the events $A_1, . . . , A_{n \choose 2}$ are...

Option (B) is wrong because energy should be received by rubber band when it is being stretched Option (D) is wrong because energy should be released by rubber band when it goes back to natural length The area between graph of stretching and contracting represents energy dissipated in rubber...

Option A is correct because the graph increases sharply at lower nucleon number Option B is correct because higher binding energy per nucleon means more stable Option C is correct because either fusion or fission will bring the product to Q So my guess the answer is D but I do not understand...

This is the V(x) diagrams and what I am thinking (really not sure though) is that for the first one you the energy has to reach V2 before it can start transmitting and the graph can take off from T=0, since there is an increase in energy potential that is V2. And as the energy increases, the...

Summary: Question regarding graphing a T^2 x L graph for a simple pendulum I did a Simple Pendulum experiment in my college physics class the other day. We were asked to graph a T^2 x L graph based off our results. I plan on using the Length on the x-axis and the T^2 on the Y-axis. This may...

N and k are positive integers satisfying $$ 1<=k < n$$ An undirected graph $$G_{n,k}= (V_{n,k} ,E_{n,k})$$ is defined as follows. $$V_{n,k}={1,2,3,...n}$$ $$E_{n,k}={\{\{u,v\}|u-v \equiv k \, (mod \, n) \, or \, u-v \equiv -k \, mod \, n}$$ However, $$x \equiv y \, (mod \, n) $$ indicates...

I understand how to show a given graph does/does not contain a 1-factor but I'm not sure how to show existence (or the lack thereof). Please advise.

Hello, good morning. I would like to know if someone knows a program to be able to draw the functions in the same way as the one shown in the image and also allow me to point out an enclosure formed by them without having to use inequalities to do so. Thank you very much for everything beforehand.

Why v vs. t graph signifies but s vs. t^2 doesn't ? This is a question which crossed my mind when I was analyzing the dimensions of the quantities.

The problem given is... Let G be a graph with no perfect matching. Then, for some $S \subset G$, 1. $|S|<O(G−S)$ 2. Each vertex in S is adjacent to vertices in at least three odd components of $G−S$. (where $O(G−S)$ is the number of odd components of $G−S$) Number 1. is the contrapositive of...

Hello I hope you are all very well. I did a graph for a physics practical work and I would like to put the "error bar" (I don't know if it's called like this, I'm sorry). Something like this: I just don't know how long the margin should be. If someone could clarify to me the way to do the...

##\gamma(G) \leq 4## ##Claim: \gamma(G) = 4## Since ##\Delta(G) = 3## a vertex can dominate at most four vertices. There are eight vertices equivalent to ##\Delta(G)##, so these are dominated by two vertices. The remaining four vertices are of degree two which require two vertices to dominate...

'Imagine that you live in a different universe, which may have a different cosmology to our own. You measure the distances to and redshifts of a large number of Type Ia supernovae, and you use the redshifts to calculate the scale-factor of the universe at the time when the supernova exploded...

I've drawn the graph and it's a straight line and I've found the slope but I don't really know what the slope represents. My slope was also 0.002 if that helps with what it represents

Homework Statement: Base of solid is the region bounded by graphs ##y= \sqrt x## and ##y=x/2##. The cross sections perpendicular to the x-axis are squares whose sides run across the base of the solid. Find volume of solid. Homework Equations: - As stated above, I will want to calculate the...

Well, this is a problem which makes you think more about concepts than numbers, so I want to see if I've done it correctly. 1) I draw a simple pendulum in an elevator, where you have weight, tension and a pseudo-force. In this situation the effective gravity may be changing due to different...

Hi, Can anyone help me understand how I get to the answer on this one? The diagram shows a sketch of the graph of y = x2 + ax + b The graph crosses the x-axis at (2, 0) and (4, 0). Work out the value of b.Thank you in advance!

Please could I ask for help with the following question: Part (a) is no problem. Acceleration is the gradient of the graph in regions OA and AB which gives 3 and 0.5 Part (b), I believe, requires me to calculate the greatest and least value of the gradient of the curve in region BC Part...

Summary: Gradient = Acceleration(?) Area = Time (?) Good evening, I have a problem that presents itself in a distance (y) velocity (x) graph. I've never come across this, and in my Physics textbook, the section dedicated to graphs does not have it. My question is, what does the area of the...
