### 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.

### How can an aircraft reduce the speed in the air?

during flight aircraft reduce speed by spoiler

### 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 should you do when operation a boat in large waves and high wind?

head into the waves at a slight angle and reduce speed

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. 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

### 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.

### 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.

### What lanes give a driver time and space to reduce their speed?

Deceleration lanes give a driver time and space to reduce their speed.
