What are road flares used for?
Road flares are commonly used by civilians for signals and may be ignited on the ground or fired as an aerial signal from a pistol-like flare gun or launched from a self-contained tube.
Distinguish between a signal element and a data element?
Signal Element Versus Data Element: Let us distinguish between a data element and a signal element. In data communications, our goal is to send data elements. A data element is the smallest entity that can represent a piece of information: This is the bit. In digital data communications, a signal element carries data elements. A signal element is the shortest unit (time wise) of a digital signal. In other words, data elements are what we need to send; signal elements are what we can send. Data elements are being carried; signal elements are the carriers.
What do you mean by passive and active elements in a electrical network?
Passive elements don't require power from the supply to produce its effect on a signal. They derive the power of the input signal to perform its action. for example, a resistor doesn't require a separate supply to provide its action of resistance in a circuit. Where as in active elements there should be a power source for its working. They require a supply for there working. For instance, transistors - Only after biasing the transitor in required region of operation, its characteristics are applied on the signal. ie, for amplification, transistor require a source from where it can work in.
What is the chemical formula for strontium iodide and why?
The uses of strontium arefireworks (red flame), flares90Sr is a radioactive isotope produced by nuclear fallout. 90Sr has the potential for use as lightweight nuclear producing electricityused to produce glass for colour television tubesrefining zincoptical materials
What elements signal the end of a stars life?
I am not aware of any specific element "signaling" this. Towards the end of a stars life, however, relatively large amounts of heavier elements are produced.
What two of this elements compound burn with a red flame and are used in fireworks and signal flares?
Lithium, strontium and calcium have red flames.
Should there be flares in football games?
Flares? Like as in road flares? or Flare guns? Flares as in the signaling devices that burn super hot and emit a blinding light usually used to signal a distress signal of some sort? I would have to think that it really wouldn't be a good idea if flares were allowed in football games.
What is the proper use of a signal generator?
A signal generator is used to shoot flares in the air from a ships deck. It can launch flares highter than typical flares and can be seen from greater distances.
What is the name of a coloured flare used for signaling at sea?
There are several different types of signal flares that can be used at sea.Smoke flares are hand-held flares. Once lighted, they give off white or orange smoke.Aerial flares are small flares that you launch into the sky.A flare gun holds red or white flares that you shoot up into the sky. These flares are quite visible at night.Parachute flares are flares that you fire into the sky, and they slowly descend. These flares have great visibility and a long burn time.very light
What is the proper procedure for using visual distress signal flares?
display only when immediate or potential danger exists
What components are flares made out of?
Flares give light or heat without an explosion and are often used to illuminate or signal. They may contain strontium nitrate or potassium nitrate as well as a fuel such as charcoal or magnesium.
