    Understanding Gravitational Force: A Simple Explanation

    Sorry about my typing. I had no idea, how to code this formula and stuff and yes I do know the difference between vectors and non-vectors (absolute value). However, I have no idea the output of \frac{\vec{P_1} - \vec{P_2}}{\left| \vec{P_1} - \vec{P_2} \right|^3}...

    Understanding Gravitational Force: A Simple Explanation

    Right. I understand. This is not a theory which i have to prove (if this then that). But I have (Gm1m2 / r^2 ) then i have to prove F = (Gm1m2 / p1 - p2) * (p1 - p2) In the hand out, it says # 3 and shows the above formula. How did they get it? (and rest of the formula) that's what i want to...

    Understanding Gravitational Force: A Simple Explanation

    I understand the Newton's law. I just don't know how to prove, that if the mass m1 and m2 are the points located at p1 and p2, the distance of those two points are equals r. I don't know how to prove this.

    Understanding Gravitational Force: A Simple Explanation

    Hi Guys... This topic was discussed in the class. Professor gave out the hand out. I tried to pay attention but couldn't follow it. Can someone explain this to me in simple English? I'm having hard time understanding this. I'm attaching a handout that I scanned...

    How Do You Compute the Flux of a Vector Field Through a Circle?

    Homework Statement Let C be the circle of radius 2 centered on the origin and contained in the plane 2x - 3y + 5 = 0. Compute the flux through C of the constant vector field v = {6, - 1, 12} I have no idea about this problem. This is one the review problem which was given to us in the...

    What is the relationship between boundedness and total boundedness in R^n?

    LOL. I was about to make a new thread about this topic. I have an exam on Wed and I was praticing couple of things. Here is my question, Suppose X € R^n is compact. Prove that X is bounded. does it make sense? did i do it right?

    Prove S is Convex: Help with Convexity

    How do i prove this? Let S = {(X1, …., Xn) € R^n | Xi ≥0, X1 + … +Xn = 1}. Show that S is convex. Suppose f(Si) = {X1, X2,..., Xn} AND g(Si) = {X1 + X2+ ...+Xn} but If do that, then f(Si) and g(Si), both will increase. Now I'm not sure where to go from here. *PS: Both functions are...

    Mathematica Help with Prim's Algorithm in Mathematica

    This is my project of Spanning Tree by using Prim's Algorithm , I have to implies this problem (#4, PIC is attached) into Mathematica ( I have version 6 btw). Which we never learned in class. Its my Applied Math class, all we do/did is theorems. We never learned a single thing about this program...

    Calculate the magnitude and direction of the electric field

    Homework Statement [1] Sphere A has a radius of 10.0 cm and carries a charge of +5.0 x 10^(-8) C while sphere B has a radius of 5.0 cm and carries a charge of -2.0 x 10^(-8) C. The spheres are conducting hollow, and concetric. A) calculate the magnitude and direction of the electric...
