What are the functions of moderater and control rods in a nuclear power plants?
Moderator such as graphite or heavy water would reduce the speed of neutron there by making them as thermal neutrons. Such slow speed neutrons are needed to bring Uranium-235 into fission. Control rods such as Boron carbide or Cadmium are there to abosorb neutrons. So chain reaction of fission is ketp under control.
What are the two substances used as moderators in nuclear reactors?
Moderators contain materials that rapidly slow neutrons down to thermal speeds without absorbing a significant number of neutrons. A few of these are:carbon, usually in the form of graphiteheavy waterlight waterhydrocarbons, like oilsberyllium (usually too expensive)etc.
What lanes give a driver time and space to reduce their speed?
Deceleration lanes give a driver time and space to reduce their speed.
In nuclear reactors do neutrons travel faster than the speed of light and if so what about the theory of relativity according to which nothing can travel faster than the speed of light?
No, the neutrons produced in nuclear reactors don't travel anywhere near the speed of light. Let's look at this a bit. In the "standard" fission reactor, fissile nuclear fuel is "started up" and the neutron chain reaction begins. Neutrons are produced during atomic fission events, and these neutrons are sometimes called "fission energy" or "prompt" or "fast" neutrons. They are the free neutrons that appear as the result of the fission event. And they're moving pretty darn quick when they're "blown out" of the fissioning nucleus. But they're not moving anywhere near the speed of light. The Boltzman distribution (a fancy way of speaking about the range of energies at which the fast neutrons appear), has a strong peak at close to 2 MeV (20 TJ/kg). That translates into a speed of 28,000 km/s. The speed of light is some 299,792 km/s as we've defined it, and that puts the speed of those fast neutrons at roughly 10% the speed of light.

How can an aircraft reduce the speed in the air?
during flight aircraft reduce speed by spoiler
What should you do when operation a boat in large waves and high wind?
head into the waves at a slight angle and reduce speed
What can moderators do on imvu?
moderators can boot unwelcome noobs or Guest_ or annoring people
What will happened to the ke if its velocity is reduced by 12 times?
Kinetic energy is proportional to the square of the speed. If you reduce the speed by a factor of 12, the kinetic energy will reduce by a factor of 12 x 12 = 144.Kinetic energy is proportional to the square of the speed.

Who are the fresboworld moderators?
The moderators of fresboworld are - Izzyshae - Smilingdog - Pixanie - Lyandor - GarethW - Tasmanian
Why is the moderator important in a nuclear reactor?
The moderator is used to slow down the neutrons present in the core of the reactor. Normally the neutrons produced as the nuclear fuel (e.g. uranium) is fissioned are travelling too fast to produce a sustained chain reaction. Some examples of moderators are cadmium, heavy water and graphite.
Can neutrons speed up passing through water?
No, it slows them.
What does reduce engine speed mean in a 2002 Chevy Tahoe?
It means some one has programmed a speed limit in the vehicle. If the vehicle exceeds the preset speed it will warn you to reduce speed.
Do you have to adhere to reduce your speed limit signs when there is no work crew present?
If the reduce speed signs are posted, yes.
What lanes give a driver time and space to reduce their speed?
Deceleration lanes give a driver time and space to reduce their speed.
