I need some guidance for this experiment.

Here's the link to the experiment*:
http://www.csulb.edu/~gpickett/ps112/the...

Ok, now I don't know how I'm supposed to graph the last graph on page 5A-8. What formula am I supposed to use? How do I get the points that I'm supposed to graph? I was told to break up the ball's bounce height (the 1st graph on pg. 5A-8) into increments, but I'm confused. Any insights, or anything really, that anyone can give me, I'd really appreciate it. Thank you.

*Oh, and I'm not supposed to actually do the experiment and bounce a ball. I'm supposed to use the graphs given.

These are both true or false:


As a nucleus gets larger,neutrons tend to change into protons and electrons?


To have the potential to be radioactive,a nucleus must always be very large?

An object is undergoing simple harmonic motion with period 1.200 s and amplitude 0.600 m. At t=0 the object is at x=0. How far is the object from the equilibrium position when t=0.480s? [[[hint the answer is .353 meters]]]

Which would be deadlier, a high powered Laser, or a large electron gun running on the same amount of electricity as that Laser?
I'm basically thinking of the electron arcs from Spealdberg's 'War of the Worlds' that the aliens use...but I have no idea what an alectron gun would go in reality.

I was told to break up the ball's bounce height (the 1st graph on pg. 5A-8) into increments, but I'm confused. Actually, I'm confused by this whole experiment! Starting with the second page, I have no idea how my hand is supposed to follow the horizontal axis for each of the graphs; it's not explained as clearly as I had hoped. So any insights, or anything really, that anyone can give me, I'd really appreciate it. Thank you.

If i am doing a report on how long it takes for a tablet to dissolve in water for a certain temperature, should I put time on the x-axis and temperature on the y-axis, or should it be the other way around?

Do Beta particles have the greatest mass of all the major forms of radioactivity?


Can Gamma radiation penetrate more deeply into materials than any other form of radiation?

Do Alpha particles tend to pick up electrons and become helium atoms?


It would be very helpful if you could explain to me the above questions.

The Superconducting Supercollider is a proton on proton collider 54 miles around that was being constructed in Texas before it was cancelled in 1993 by congress|
---
Now the question is, should it be resurrected?
---
The Large Hadron Collider is now being constructed in Europe by the European Laboratory of Particle Physics (CERN)| It will be operational late this year| It will be a particle accellerator at 14 trillion electron volts which is seven times more powerful than the Tevatron, which is at present, the most powerful accellerator in the world.
---
The LHC, it is hoped, will verify such phenomena as the Higgs particle (that gives all other subatomic particles their mass), supersymmetry, micro-black holes, and extra dimensions|
---
The SSC has an energy of 40 TEV|
-
Although the luminosity of the SSC is considerably lower than the LHC, the higher energy could be an advantage

A bullet with a mass of 6.00g is fired through a 1.25kg block of wood on a frictionless surface. The initial speed of the bullet is 896m/s, and the speed of the bullet after it exits the block is 435m/s. At what speed does the block move after the bullet passes through it?

I need the calculations used as well as the answer - I'm homeschooling my kids, but I don't get it. Thanks!
