I'm currently in an advanced laboratory for physics majors, and I'm conducting a pulsed NMR experiment. My partner and I decided that we we're going to measure the T1 and T2 times of Epoxy. The idea is to explore the relationship between curing epoxy and changing T1 and T2 times. We have results...

I'm pretty sure the way that they're defining "at risk" is: students who's educational experience could be affected by external factors including socioeconomic problems. I haven't been officially hired into the position yet, so as far as program details go and their selection process my...

Nice! That gives me some good ideas :) Thank you very much!

Hello everyone! I'm writing today because I was wondering what you might think about this. Right now I'm working on writing a curriculum for a summer program for at risk 11th and 12th graders. The summer program is two weeks long and the Physics class meets 3 times a week for an hour a half...

It was right! Thank you very much :)

Homework Statement TRUE or FALSE for each statement: *Only very small objects have a wave function. *Electrons show interference effects like waves. *The wave function times the volume gives a measure of the probability of finding a particle in a particular region. *The absolute value of...

Oh, wow, duh. I guess I let the language get the best of me. Thank you!

Homework Statement Find the point on the line y = 2x+1 that is closest to the point (5,2) Homework Equations Vector Projection (x^Ty/y^Ty)*y x and y are orthogonal (angle between them 90 degrees) if: x dot y = 0 The Attempt at a Solution There's a similar example in my book, but...

Ha, yeah. Sorry... x1 = {2,1,3} x2 = {3,-1,4} x3 = {2,6,4}

Homework Statement x1, x2, and x3 are linearly dependent. Show that x1 and x2 are linearly independent. Homework Equations After reduction using gaussian elimination, x1, x2, and x3 are proven to be linearly dependent because x1 and x2 are defined by x3 (being the free variable) as...

Homework Statement A particle of mass m at the end of a light string wraps itself about a fixed vertical cylinder of radius a. All the motion is in the horizontal plane (disregard gravity). The angular velocity of the cord is w0 when the distance from the particle to the point of contact of...

Thank you!

Homework Statement A typical fission reaction is U(92,235) → Zr(40,98) + Te(52,135) + 2 n The numbers in parentheses are (Z,A) for each isotope; n stands for a neutron. The atomic masses of the isotopes are: U(92,235) = 235.043923 u; Zr(40,98) = 97.912746 u; Te(52,135) = 134.916450 u; n =...
