i have three vectors: a=4,b=3,c=5 that form a right triangle. vector a is in the positive x direction, vector b is in the positive y direction starting at the tip of a. vector c is the hypotenuse of the triangle with tip at the origin. (see attaced picture .doc file) the questions are...

What would the Lewis structure look like for Cl F? Would it look like this: http://img53.exs.cx/my.php?loc=img53&image=dot8pn.png How do you know when there is a triple bond? ~Thanks

How do you say... \dot{Q} ...Dot cue?

I'm sorry if this is placed under the wrong section of the forum. But i really need help with a problem. Well, here it is; Find a unit vector that is parallel to the xy-plane and perpendicular to the vector 4i - 3j + k *note* there is a ^ above the ijk.

A disk 8.0 cm in diameter is initially at rest. A small dot is painted on the edge of the disk. The disk accelerates at 600rad/s^2 for .5s, then coasts at a steady angular velocity for another .5s. What is the speed of the dot at t = 1 s? Through how many revolutions has it turned? I...

Let n = (a,b,c) v = (x,y,z) Whatever the dot product of these vectors equal to, let's call d, the vector n is perpendicular to v. Again, I cannot stay calm and ask WHY? If we call n = (a,b); v= (x,y) ==> ax+by= d and the slope of this line is -a/b whereas the slope of the vector n is...

I need some major help with some dot products. I was curious if when getting the dot product, you add the angles of each one to each other. I'll give the problem: theta=(/) Find A*B(dot product) A=8.6i+5j B=9.7i+2.6j So i used the formula my teacher gave me to find the angle, theta...

http://www.cs.princeton.edu/~bourgui/misc/pix/pale_blue_dot.jpg Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering...

Hi, I got a simple question, "dot product" have units? I mean, if A=(Ax+Ay+Az)N and B=(Bx+By+Bz)(cm/s) , the units of A.B will be N.(cm/s) Thanks, Cali

Hello, I was hoping someone here might be able to explain to me how to determine electron dot diagrams and structural formulas of diatomic/polyatomic elements and compounds. For example... Nitrogen Tri-iodide ( NI3 ) I know the basics of electron dot structures, but when the atoms start...

The angle between vectors a and b is cos^-1(4/21). Find p if a = [6,3,-2] and b = [-2, p, -4] I did: cos x= 4/21 = a.b/|a||b| The result comes out to be p=8/3 but it only satisfies that a dot b is 4 and not |a||b| = 21...What am I doing wrong?

Here's what I got to prove where '.' is dot. A.B=A.C Then B=C True or false? If true, prove it in general terms, if false, provide a counter-example. Ok, I just need some body to comment on my little proof here, and any guidelines to make it more thorough or whatnot. I know that the dot...

[SOLVED] dot and cross product vector Hi! The quantity (absolute value vectorA x vectorB close absolute value)^2 + (absolute value vectorA * vectorB close absolute value)^2 is equivalent to: I am confused, a close example used numbers in place of the vectors so I gave it a try in a book I...

Hey, i was just wondering what envelopes with a big black dot on them means. Also, i was wondering if there was a better way i could ask a question like this, it seems a bit silly to post a whole thread, just for a dumb quetsion...
