What happens when the positively charged alpha particle directly hits the positively charged nuckeus?
When a positively charged alpha particle collides with a positively charged nucleus, they experience a strong repulsive force due to their like charges. This repulsion can prevent the alpha particle from penetrating the nucleus. If the energy of the alpha particle is sufficiently high, it may overcome the Coulomb barrier and interact with the nucleus, potentially leading to nuclear reactions such as fusion or scattering. However, under normal circumstances, the alpha particle will simply be deflected away from the nucleus.
What is the result radioactive decay?
One type of atom (nuclide) breaks up, emitting some particle and energy, and converting into another type of nuclide.
How can an object follow an unbound orbit?
Unbound in this context means, that the distance from the particle orbiting (e.g. earth) to its focal point (e.g. sun) is not bound and can become infinite. In a bound orbit, this is not possible. The orbiting particle will always be closer to its focal point than a maximal radius. It can not escape to infinity. This also works for an infalling particle, where the radius is not bounded from below and can become 0, i.e. it collides with the focus. In this case, there is no minimal radius. (technically, there is one, but it is 0). To summarise: unbound means, either the orbiting particle escapes to infinity or collides with it's focal point at some time.
How would you explain an individual particle with string theory?
An individual point particle in the standard model is described in string theory as a mode of vibration of a string. If for some reason the mode of vibration of the string changed, the particle would change to a different one.

What is fission in physics?
In physics, fission is the process in which a heavy, unstable element is split into two lighter elements by bombarding it with a small particle. Some of the energy that was binding the element's nucleus together is then released, along with a third, tiny particle that is released as well. The tiny particle then collides with another of the heavy elements, causing it to split as well, emitting another particle which collides with another heavy element, and so on. This is the chain reaction that allows for sustainable nuclear power generation, in which the reaction is controlled, or the detonation of nuclear weapons, in which the reaction is uncontrolled.
What happens when an acid particle collides with an alkali particle?
After the chemical reaction, a salt is produced and water. For example: HCl (aq, acid) + NaOH (aq, alkaline) → H 2O (water) + NaCl (aq, salt)
What type of particle is emitted when a U-235 decays to Np-235?
It is negative beta particle emitted by a uranium nucleus and converting it to neptunium nucleus.
What is radiation particle used in bombardment of nitrogen-14?
The radiation particle used in the bombardment of nitrogen-14 is a neutron. When a neutron collides with a nitrogen-14 nucleus, it can create carbon-14 through a process called neutron capture.
How do particles conduct heat?
When particles receive energy (like heat) usually it causes the particle to vibrate. If this particle is next to another particle, the vibration causes the particle next to it to vibrate. This vibration is the heat energy being given off, and colliding with the next particle, which then collides with the next particle, then the next, etc.This is the case with solid and liquid particles, however gas particles use convection, which is where the gas particle hits another particle, and so transfers some of the energy (such as heat) to that particle.Conduction ConvectionA;vibrate;B;vibrate:C A->->->;collide;B->->;collide;C

How does energy move between particles in conduction?
In conduction, energy is transferred between particles through direct collisions. When a particle with higher energy collides with a particle with lower energy, it transfers some of its energy to the lower-energy particle. This process continues throughout the material, allowing energy to move from hot regions to cold regions.
How does heat travel by conduction?
Heat, on a molecular or atomic level, is kinetic energy; fast moving particles are literally hotter. So, if a fast moving particle collides with a slower particle, there will be an exchange of energy. We know from basic physics that force equals mass times acceleration, so when a force is applied to a particle, that particle will accelerate. That is how heat is transferred particle by particle. All of this happens on such a small, sub-microscopic scale, that we do not see the mechanics of it, we just see heat being conducted.
How do atoms in a liquid transfer heat to nearby atoms?
On a molecular scale, thermal energy is the kinetic energy of individual particles. In a liquid, this thermal energy is transferred to nearby atoms by collisions; a high-speed particle in the liquid collides with a lower-speed particle, transferring some kinetic energy from the high-speed particle to the low-speed particle. When this happens with a large number of particles, thermal energy transfer results.
What are the differences between free settling and hindered settling?
when the particle do not collide with the wall of the container or with the other particles is called free settling the suspended particles in the medium do nor effect it and when the particle collide with the other particles and with the wall of the container an d collides with the suspended particles is called hindered settling
How is heat transferred from particle to particle through conduction?
In conduction, heat is transferred through direct contact between particles within a material. When a warmer particle collides with a cooler one, it transfers kinetic energy to the cooler particle, causing it to vibrate more rapidly and increase its temperature. This process continues as neighboring particles transfer heat energy through a series of collisions, leading to the overall transfer of heat through the material.
Why do different solids transfer heat at different rates?
