The initial velocity after fission is something like 30,000 km/sec, 10 percent of the velocity of light. In moderated reactors the neutrons are slowed down by collisions with the moderator atoms and eventually (if not captured) arrive at the mean velocity of the moderator atoms themselves, or more correctly they achieve the same distribution of such velocities, which is around several km/sec depending on the moderator material and its temperature. These neutrons are then said to be thermalised as they have come into equilibrium with the thermal related moderator velocity distribution.
Fast neutron energy is characterized by high kinetic energy levels, making them effective for inducing nuclear reactions. These reactions can be utilized in nuclear power generation, nuclear weapons, and neutron imaging techniques. Fast neutron reactors can also help reduce nuclear waste and increase fuel efficiency in the nuclear industry.
uranium 238 is a fast neutron absorber the answer is correct but for more explanation:- when uranium 238 is bombard by neutron >>> uranium 238 , undergoes B decay>>>Np 239 ,undergoes B decay >>> Pu 239 finally undergoes alpha decay >>> fissile U
Fast film speed can lead to increased graininess in the images, which can reduce image quality. Additionally, fast film speed may have limited dynamic range and color accuracy compared to lower speed films. Fast film speed can also be more expensive than lower speed films.
Stataneous speed refers to the speed of an object at a particular instant in time. The speed could be fast or slow depending on the object and context in which it is moving.
Velocity, or Speed
No, a photon always moves at the speed of light, and nothing with non-zero mass (which includes neutrons) can move that fast
When U-238 absorbs a fast neutron it forms plutonium-239
In order to cause an atomic nucleus to become unstable so that it will undergo fission, you have to add a neutron. If a slow neutron collides with an atomic nucleus, it will be absorbed into the nucleus and become part of it. The nuclear attraction of the nucleus is strong enough to grab a slow neutron. But a fast neutron cannot be captured because it has too much kinetic energy. The attraction of the nucleus is not enough to stop the motion of a fast neutron. Even if a fast neutron makes a direct hit on an atomic nucleus, it is just going to bounce off.

Fast speed boats are made of materials that are used to make fast speed boats.
The element is determined by the number of protons. When uranium captures a fast neutron it is still uranium but has an increased atomic mass. Fast neutron capture may encourage a further reaction but it depends on which uranium isotope you start with as to the increase in probability some further reaction will occur and which reaction that might be.

Beta decay releases a fast-moving electron (beta particle) from a neutron in the nucleus. During beta decay, a neutron is converted into a proton, and the electron and an antineutrino are emitted to conserve charge and energy.
Yes that is quite a fast speed!
That depends on the speed. After deciding how fast you will travel, divide the distance by the speed to get the time.That depends on the speed.

The speed limit in the fast lane is the same as the speed limit for the road or highway you are driving on.
