A neutron is a subatomic particle; it is one of the building blocksof the atom. It has a mass of about 1.675 x 10-27 kg. It's spin is+ 1/2 and that makes it a fermion. Additionally, it has no electriccharge. It is unstable when free in nature, and has a half life ofabout 886 seconds. The neutron cou…ld be said to be only "alive" tobe part of an atomic nucleus as it ceases to exist after a while ifleft alone. When it wanders around loose, like after its releasefollowing a decay event or a fission event, it may bump intoanother atomic nucleus and become captured by it. This process iscalled - no surprise - neutron capture. It is, after all, anucleon, as is a proton, both of which make up an atomic nucleus.The neutron is made up of two down quarks and an up quark. When aneutron decays, it releases a proton (or, if you prefer, a hydrogennucleus), an electron, and an antineutrino. ( Full Answer )
Neutrons can be thought of as the combination of a proton and an electron, though there is a little more mass in them than in a proton and an electron. Most neutrons are formed by the fusion of 4 hydrogen atoms (one proton and one electron) into helium (2 protons, 2 electrons, and 2 neutrons). Thi…s occurs mainly deep within stars. Neutrons can be generated or obtained in a variety of ways. One is entirely natural - they are emitted when uranium-235 undergoes fission. They are generated when alpha particles collide with some atoms of low atomic weight, such as lithium, carbon, or oxygen. Gamma radiation colliding with certain isotopes, including deuterium and berrylium-9, produces neutrons. Fusion produces neutrons, and a fusor can be used for this. Neutrons are produced through a process called spallation when high energy protons impinge on heavy atoms such as lead or bismuth. Free neutrons have a short half life, about 886 seconds, or a bit less than 15 minutes. When they decay, they emit a proton, an electron, and an electron antineutrino. ( Full Answer )

5c:pretty tough =o 1) there should be 2 exits at the bottom left, so put on portal in each, then let go of the ball 2) The ball will bounce/roll and pass the 2 point things, and the moment it passes through the second, pause and restart the whole thing (this is to make sure the ball will fall st…raight). 3) move the left bottom portal,(which is facing right) to the top right exit (which is facing down), then let go of the ball. Let it go through the portal, and by the time it has gone through and is about to touch the bottom, pause the ball, and move the bottom left portal to the exit that is facing the other portal 4) let it gain some speed, and once it cant go much faster, pause the ball. 5) leave the bottom right portal alone, and move the other one at the bottom left, the exit *facing* the blackhole thing. The speed will catch it, and it will teleport the ball to the last point thing 6) reverse every thing to the start, and move the bottom right portal to the top left, the one almost facing the finish, then let go of the ball.

Neutrons in an atom Equation Atomic Weight - Atomic Number = The neutrons of an element Round for the final answer Example: Sodium (Na) Atomic Number: 11 Atomic Weight: 23 23-11= 12 neutrons so therefore sodium has 12 neutrons
Well, in the steams list of games which you can use on garrys mod it dosent show Half life Source. But if you type in gman squad on youtube you can see their playing the storyline on Half life Source. I asked them the same question and they said yes, you can play the storyline if you have garrys mod… and Half Life Source. I dont know for sure because i have not yet tried it. ( Full Answer )
Neutrons are particles in the nucleus of an atom which have slightly more mass than a proton. They contain neither a positive nor a negative charge. Neutrons bind with the protons in the nucleus, and are stable there. If they are insufficient in number, or there are too many, they may cause the ato…m to be unstable and radioactive. When they are not bound into an atom, they do not last long, and have a half life of just a bit less than 15 minutes (886 seconds). ( Full Answer )

Neutrons are particles in the nucleus of an atom which have slightly more mass to a proton. They contain 0 charge. They help determine the stability of the atom in which they are bound. When they are liberated from an atom, as in fission, they bounce about from one atom to another giving off heat… and slowing down as they do so. If they hit an atom at just the right energy, they can cause the atom to undergo fission or otherwise decay. They can also be absorbed into atoms, changing their isotopes. When they just bounce, the energy they impart is often enough to cause molecules to break apart. But in general, since they have no charge, they can plow right through atoms without much interaction, and so they can penetrate some substances quite deeply. ( Full Answer )
Half Life is the original game released in the late 90's. This also include the popular multi-player mod Counter Strike. 'Source' is the name of the new game engine that was designed to run it's sequel Half-Life 2. The updated version of Counter Strike that uses this engine is called CS:Source. 'Hal…f Life: Source' is a remake of the original Half Life using the updated engine. [stormroad says] [basicley its the a little better quallity of the game but not half life 2 quallity] ( Full Answer )
It's obvious. if you're too cheap to pay $10 then you illegally pirate it. Doesn't that sound like a grea t idea?! Anyway, to register a game yents pou bought you need to put the product key which prevents piracy.
That's what I have been looking for. Please help me in answering this question.... PLEASE! >:( IM BEGGING YOU! :0
The Iphone 5C is Iphone 5Colorful 5c can also stand for thenumber 500 ("c" is the Roman numeral for 100) or for 5 degreesCelsius (centigrade) . +++ . "5c" can not stand for any Roman numerals forthree reasons. For a start you do not mix Arabic and Roman numeralslike that - it would be nonsensica…l. Secondly, the Roman for 100 is capital " C ", but thirdly, in the Romanscale, 5 is V, 50 is L and 500 is D. The ' C ' isalso capital for degrees Celsius / Centigrade. ( Full Answer )
neutrons are produced at a rate of 2.8x10 +6 neutrons/second/curie Am-241 for an optimally, well mixed source of americium and beryllium. the neutron dose rate of a one curie Am-Be source would be 34.7 mR/hr (or 347 ÂµSv/hr) at 30 cm. the gamma dose rate of a one curie Am-Be source would be 0.17 …mR/hr (or 17 ÂµSv/hr) at 30 cm. americium-241 also decays by spontaneous fission with a half life of 2x10 +14 years, producing 0.18 neutrons/second/curie Am-241. note that beryllium is not required for this neutron production mechanism.

If you can prove you need it, you can get a license for one. Companies who drill for oil all have them; they are used to test the density of the ground they're working in.
Uranium-235 undergoes a small rate of natural spontaneous fission, so there are always some neutrons being produced even in a fully shutdown reactor. When the control rods are withdrawn and criticality is approached the number increases because the absorption of neutrons is being progressively reduc…ed, until at criticality the chain reaction becomes self sustaining. Note that sometimes a neutron source is provided in the reactor, but this is not essential to start the chain reaction, it is to give a shutdown neutron population which is detectable by instruments and so make the approach to critical more observable. The reactor will go critical at the same control rod position whether a source is loaded or not. ( Full Answer )
No. Half-Life: Source runs on the Source engine. The original Half-Life doesn't. You cannot use mods made for the original Half-Life on Half-Life: Source because they run on different engines and it won't work.
A neutron star no longer produces energy - it is a dead star. It will gradually get colder, until it stops emitting any significant amount of heat. Any heat the neutron star radiates is residual heat - heat that was produced earlier, either through fusion, or through the tremendous gravitational col…laps that produced the neutron star.

Yes it can. It runs quite well in Windows Vista. The original Half-Life doesn't, so if you use Vista, I strongly recommend you go with the Source version.
There are multiple animals on 5 cent coins depending on the country and time period such as the Buffalo on the US "buffalo nickel", the Beaver on the Canadian nickel, etc.
Half-life has nothing to do with the safety of radioactive sources, quite the opposite. The half life is the time it takes 50% of the given atoms in a sample to decay into another element. The shorter the half life, the more changes taking place and the more electrons being radiated into the air.… Those electrons pierce living tissue and that's what causes the radioactive harm. Eventually, some atoms will reach a point of stability when they have shed these extra subatomic particles and no longer emit radiation, but even once decayed for the first time, there can be many more radioactive events to come.

You can't tell a thing about -5c+9 until you know what 'c' is. And every time 'c' changes, -5c+9 changes.
A US five cent piece weighs 5.00 grams, has a composition of 0.750 copper & 0.250 nickel and a diameter: 21.2 mm.
the half-life is the time it takes for half a given quantity radioctive material to decay into more stable elements.
A neutron source. Examples are: . Polonium alpha source, beryllium absorbs alpha and emits neutron. . Radium alpha source, beryllium absorbs alpha and emits neutron. . Electrically activated tritium fusion neutron source. . etc. For a bomb the source must emit roughly 10 neutrons during the… nanosecond of maximum supercriticality (10 billion neutrons per second) to prevent a fizzle and maximize yield. For a reactor in startup a much less intense source is needed but it must be continuous (the source in the bomb can be a short pulse). ( Full Answer )
The only animal to appear on the 5c coin in US currency is thebuffalo (1913-1938) Canadian 5c coins normally have a picture of a beaver building adam, although special commemoratives issued during the 1967Centennial carry a picture of a snowshoe hare. Australian 5c coins have a picture of an echid…na, which is anunusual egg-laying mammal found only in that country. New Zealand 5c coins carried a picture of a reptile called atuatara. The denomination was eliminated in 2006 due to lowpurchasing power. ( Full Answer )
To get the chain reaction started at the right time relative to the assembly of the supercritical mass. Like ignition timing in a car's engine, you don't want it too early or too late. In an atomic bomb too early severely reduces yield, too late runs the risk of spontaneous fission starting the ch…ain reaction giving melting of the bomb and a fizzle. ( Full Answer )
5cc? cc means cubic centimetres which is equal to ml, so 5ml. if you mean cl, then that is equal to 50ml
The 'answer' is the number that 'c' must be, if 5c is really the same as -75. In order to find out what number that is, you could use 'algebra'. First, write the equation, so that you can look at it: 5c = -75 Now, use the law of algebra that says: "If equals are divided by equals, then… the quotients are equal". The left and right sides of your equation are equals. Divide them both by 5, and that law says that the quotients on both sides will be equal: c = -15 ( Full Answer )
A collet is used for clamping purposes. It forms a collar around an object, and clamps down on it as it is tightened. A 5C collet has external threads used for lathes.
Half Life Source is a direct port of the original to Valve's source engine meaning that like Half Life it is a science fiction first person shooter. The only difference between it and the original Half Life being slightly improved graphics.

The answer to this is always subjective, based on what you'relooking for in a phone. If you like the iPhone, then you willprobably like the 5c. If you prefer the Galaxy series (or anotherAndroid phone), you might loathe the 5c. If you're coming from a Blackberry or a Windowsphone, you might be ind…ifferent. ( Full Answer )
The neutron source in a typical reactor is Antimony pins insideberyllium sleeves The antimony emits gamma rays and the berylliumconverts the gamma rays to neutrons. The neutrons place the in coreinstrumentation onscale so that criticality can be approachedslowly and safely.
