What happens when a positron and a electron collide?
When a positron and an electron collide, they annihilate each other and produce gamma rays. This process is known as electron-positron annihilation. The total energy of the particles is converted into electromagnetic energy in the form of gamma rays.
What happens when two photons collide with each other?
When two photons collide with each other, they can either scatter off in different directions or combine to create new particles, such as an electron and a positron. This process is known as pair production.
Describe what happens when a position and a electron collide?
The collision of a positron and an electron is either a scattering event or a mutual annihilation event. Remember that the positron is antimatter; it's the antiparticle of the electron. It has a positive charge and will be attracted to electrons (or anything else negative). If a positron has extremely high energy, it will have to "slow down" before it and an electron can "mutually capture" each other and annihilate each other. Let's look at a positron with high kinetic energy that is moving very quickly through some medium like air or water. In scattering, the positron whizzes by an electron of an atom and some energy is exchanged. The positron will give a bit of energy to the electron, and how much will be determined by the energies of the positron and the electron, and some "probabilities" regarding the scattering, which could be either inelastic or elastic scattering. The net result is that the positron will leave the area moving a bit less rapidly. It lost energy (has less kinetic energy), and it is slowing down. As it slows, it experiences an increasing probability that it will be able to combine with an electron. The more it slows down, the more likely the "combining event" will become. When the positron "bumps into" an electron after slowing down, that positron and the electron will "combine" themselves, and all of their mass will be converted into energy. This energy will be carried off by a pair of electromagnetic rays, two gamma rays. And they'll have considerable energy and be moving in opposite directions. Conservation laws will have been upheld in the reaction. The combination of matter and antimatter results in mutual annihilation, and the two particles completely disappear, having had all of their mass converted into energy.
What happens to a positron when it encounters a magnetic field?
When a positron encounters a magnetic field, it will experience a force due to its positive charge and the direction of the force will be perpendicular to both the velocity of the positron and the magnetic field. The positron will move in a curved path due to this force, following a trajectory dictated by the strength and orientation of the magnetic field.
What happens to the energy of a vibrating electron that does not collide with neighboring atoms?
The energy of a vibrating electron that does not collide with neighboring atoms can dissipate as electromagnetic radiation in the form of photons. This process is known as spontaneous emission. The electron can also transfer its energy to nearby electrons through a process called resonant energy transfer.

Does an electron-positron collision violate the law of conservation of matter?
No, electron-positron collision does not violate the law of the conservation of matter. Momentum and charge are also conserved. Electrons and positrons can collide in what are called scattering events, and they can do this without necessarily undergoing mutual annihilation. Because both these little critters can exist as a wave (particle-wave duality), their behavior can be fairly easily assessed using a "basic tool kit" to analyze electromagnetic wave interaction. But electrons and positrons can annihilate each other rather than scatter. Annihilation doesn't violate the law of conservation of matter, either. And there's a reason for that. The "old" idea of the conservation of matter was that matter could neither be created nor destroyed. But we now know that matter can be converted into energy. That's what happens in annihilation. The article in Wikipedia on the annihilation event touches on electron-positron collision. And there is an article on electromagnetic scattering as well. They aren't that difficult to understand, and the curious person will find links to those posts below.
Why a free neutron does not decay into electron and positron?
What makes you think that it should decay precisely into an electron and a positron, rather than some other option?Anyway, in any such particle conversion, certain quantities must be conserved. Some of these conservation laws are strict (no exceptions are known to exist), some not (now and then there is an exception). For the proposed reaction, you should consider the following conservation laws:Conservation of mass/energy - the electron and the positron have much less mass than the neutron. This would not pose a significant problem, since they could move away from each other at a high speed - the missing mass/energy would be present in the form of kinetic energy. This indeed happens in some particle reactions.Conservation of momentu - no problem here, either.Conservation of electric charge - no problem here.Conservation of baryon number - this would NOT be conserved in your proposed reaction. Please note that this is not a strict conservation law; there are known violations. However, violating the baryon number in a particle conversion is quite uncommon. In this case, the neutron has a baryon number of +1, the proton (one of the decay products of the actual decay) also has a baryon number of +1, while electron + positron would have a baryon number of 0.
How do you explain What Happens When continents Collide?

In high-energy physics what happens when two gamma ray photons meet?
When two gamma ray photons meet, they can undergo a process called pair production, where they can create an electron-positron pair. This process demonstrates that energy can be converted into matter.
What is an annihilation reaction?
Annihilation reaction is when you take matter and anti-matter and try to put them together and they cancel each other out. Try putting an electron and a positron together. What happens? They will cancel each other out.
