Mass spectrometer

A mass spectrometer is a tool used to determine accurately the mass of individual ionized atoms or molecules, or to separate atoms or molecules that have similar but slightly different masses. For example, you can deduce the age of a small sample of cloth from an ancient tomb, by using a mass spectrometer to determine the relative abundances of carbon-14 (whose nucleus contains 6 protons and 8 neutrons) and carbon-12 (the most common isotope, whose nucleus contains 6 protons and 6 neutrons). In organic material the ratio of 14C to 12C depends on how old the material is, which is the basis for "carbon-14 dating." 14C is continually produced in the upper atmosphere by nuclear reactions caused by "cosmic rays" (high-energy charged particles from outer space, mainly protons), and 14C is radioactive with a half-life of 5700 years. When a cotton plant is growing, some of the CO2 it extracts from the air to build tissue contains 14C which has diffused down from the upper atmosphere. But after the cotton has been harvested there is no further intake of 14C from the air, and the cosmic rays that create 14C in the upper atmosphere can't penetrate the atmosphere and reach the cloth. So the amount of 14C in cotton cloth continually decreases with time, while the amount of non-radioactive 12C remains constant.

Here is a particular kind of mass spectrometer (see the figure). Carbon from the sample is ionized in the ion source at the left. The resulting singly ionized 12C+ and 14C+ ions have negligibly small initial velocities (and can be considered to be at rest). They are accelerated through the potential difference ΔV1. They then enter a region where the magnetic field has a fixed magnitude B = 0.15 T. The ions pass through electric deflection plates that are 1 cm apart and have a potential difference ΔV2 that is adjusted so that the electric deflection and the magnetic deflection cancel each other for a particular isotope: one isotope goes straight through, and the other isotope is deflected and misses the entrance to the next section of the spectrometer. The distance from the entrance to the fixed ion detector is a distance of w = 29 cm. There are controls that let you vary the accelerating potential ΔV1 and the deflection potential ΔV2 in order that only 12C+ or 14C+ ions go all the way through the system and reach the detector. You count each kind of ion for fixed times and thus determine the relative abundances. The various deflections insure that you count only the desired type of ion for a particular setting of the two voltages.

(b) Determine the appropriate numerical values of ΔV1 and ΔV2 for 12C. Carry out your intermediate calculations algebraically, so that you can use the algebraic results in the next part.

ΔV1 = ?V

ΔV2 = ?V

(c) Determine the appropriate numerical values of ΔV1 and ΔV2 for 14C.

ΔV1 = ?V

ΔV2 = ?V

I am building a model airplane and i woudl liek to know what the ratio of an airplanes tail to it wingspan or tail to any other part of the palne is and what is the ratio of the propeller (i am using a rubber band propeller) to and part of the airplane is, thank you for your time please answer.

Which Wrestling or Lucha Libre companies do you think are the biggest competetion for the WWE?

I would like to know if there are and trolls left in the Wrestling Section and how many are there?

Also do you think that the current Vicky Guerrero/UnderTaker situation can lead to the return fo the Ministry of Darkness?

I surely a little late, but who won at the recent pay per view rey misterio or kane?

Well, last year I heard that Mistico was to join the WWE, but now he is waiting to see which wrestling promotion gives him a better deal, so do you think he will stay in the CMLL or go to the WWE or TNA?

-Also do yout hink Mistico deserves this chance and if not what luchador do think deserves the chance and why?

1.What were the Summer Slam results

2.I had heard that El Misitco was going to sign with the WWE, is that still goign on or is Mistico goign to stay in the CMLL?

I saw a martial arts movie a few years back and would like to know its name since the movies name was never mentioned on the channel I was watching, the movie involves three kids two boys and a girl who are reading a comic book a believe and talk about something like the White Eagle and the Cobra Con organization, which is polluting the environemnt and having a litttle kid as its mastermind who is brainwashed and is released form his brainwashing after the three kids beat him in a virtual reality martial arts video game, the three kids also act as vigilantes.

-So if you know what movie it is can you give me its name and possible a link to a site that has information on the movie?

-I think there was once refrence to the organization in the movie on family guy when I believe Stewie told Brian that he was going to get his friends from Cobra Con or somehting like that

I believe what Kane did was a trick, but technically the Rey Misterio Jr. mask, this Rey Misterio's original mask was lost in a mask title match in WCW so technically Rey Misterio Jr. is dead, and the WWE might be planning a revival for Rey in that they want him to go back to his Lucha Libre roots and style back when he was more high flying, more crazy, and more suicidal, what better way to do that by reviving the Rey Misterio Jr. mask, which I believe was the mask in Kane's bag. So I believe that Kane might have been asking is Rey Misterio Jr. dead or alive, because the WWE Rey isn't as entertaining as when he was Rey Misterio Jr. and the WWE wants him to be entertaining
