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...
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...

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.

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...
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...
Homework Statement
One of the beams of an interferometer, as seen in the figure below, passes through a small glass container containing a cavity D = 1.34 cm deep. When a gas is allowed to slowly fill the container, a total of 222 dark fringes are counted to move past a reference line. The...
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 =...
