Figure these out and win a prize part 2
 

I'm sick of figuring out these problems so I'm offering a prize if you can figure these out before 5:00 eastern time today. You don't have to answer them all if you can't. Good luck, great prize ;):

1. An electron is accelerated through a potential difference of 1.3 kV and directed into a region between two parallel plates separated by 20 mm with a potential difference of 180 V between them. The electron is moving perpendicular to the electric field when it enters the region between the plates. What magnetic field is necessary perpendicular to both the electron path and the electric field so that the electron travels in a straight line?


2. Physicist S. A. Goudsmit devised a method for measuring accurately the masses of heavy ions by timing their periods of revolution in a known magnetic field. A singly charged ion of iodine makes 14.00 rev in a field of 45.0 mT in 2.58 ms. Calculate its mass, in unified atomic mass units. Actually, the mass measurements are carried out to much greater accuracy than these approximate data suggest


3. In a certain cyclotron a proton moves in a circle of radius 0.30 m. The magnitude of the magnetic field is 1.0 T. The mass of a proton is 1.673e-27 and the cyclotron frequency is 1.52e7 What is the kinetic energy of the proton, in electron-volts?

dumb ----, just drop out :P

Re:Figure these out and win a prize part 2
 

Try this one : what is the kinetik energy of a warm brick! if you have the answer you get a prize!

I was more leaning towards killing myself but your idea seems less drastic. :P I guess I shouldn't have skipped class all week and wait till 4:00a.m. to start it. :-\

Re:Figure these out and win a prize part 2
 

send me the prize and you get the anwser. :P

Re:Figure these out and win a prize part 2
 

I already had to take take modern physics / quantum mechanics but after i took it I gave it back. I think my class average was like 50%

Re:Figure these out and win a prize part 2
 

is this chemistry or physics? ???

Re:Figure these out and win a prize part 2
 

1. your talking about like at a drag strip when you pass threw the lights and what not? or you talking about how UFOs fly? or how the trains that are magnetic?

Re:Figure these out and win a prize part 2
 

Physics. quantum mechanics was more chemistry and I made that my bitch 8) This is just simple magnetism.

lol, im lost too

Re:Figure these out and win a prize part 2
 

you stupid crackers. So none of you dumbasses know?

Re:Figure these out and win a prize part 2
 

nope were all stupidedededededed ;D ::) :P

Re:Figure these out and win a prize part 2
 

Turbo it. :D

Re:Figure these out and win a prize part 2
 

call kyle :P

Re:Figure these out and win a prize part 2
 

Im glad I dont have to take these classes :D

Re:Figure these out and win a prize part 2
 

I think it's 7

Re:Figure these out and win a prize part 2
 

if Kyle have another account he should have answered it already LOL

Re:Figure these out and win a prize part 2
 

He's PMing me, but he's not familiar with some of this stuff.

Re:Figure these out and win a prize part 2
 

how you figure?

Re:Figure these out and win a prize part 2
 

x = y yo ;D

Re:Figure these out and win a prize part 2
 

I think Dr. Boost might need to do an IP ban and maybe another SN will disappear.

Re:Figure these out and win a prize part 2
 

ip ban = no
user ban = maybe

Re:Figure these out and win a prize part 2
 

ip ban, yes

Re:Figure these out and win a prize part 2
 

add the mass of the proton and the frequency and divided by the magetic feild to figure out the kenitic energy. You might have to put some chemistry equation along with that by figure out the mass of the element to end up with 3 sig figure of the problem im not really sure but its along that :-X

---- you bitch

Re:Figure these out and win a prize part 2
 

The key to the third question is probably in here somewhere

Right here, I think:

Too bad the thing uses stupid colours and transparency.

meh, at least you can see the x. Can't see ---- with the original graphic.

Re:Figure these out and win a prize part 2
 

haha

Whitey, I'd figure this ish out if I had the time.. but I dont.. so good luck :-*

Re:Figure these out and win a prize part 2
 

Chocolate milk give me the runs.....BTw i dont have an answer....

Re:Figure these out and win a prize part 2
 

Sounds likle PhysII CAPA. I hated that bitch. It been like 3 years ago but I can figure them out, whats the prize. PM me
