Why atomic clocks are stopped for one second on 31st of December each year?

This doesn't happen every year. It is due to happen in 2008. The last one was in 2005. It is the same as why we have a leap day every 4 years. A year is about 365.25 days long, not 365 days. To make up for that, we add a day every 4 years. A leap second is added to keep time accurate, as the rotation of Earth is slowing. Otherwise our time would become out of synch with the way the Earth rotates and orbits the Sun. There are a number of factors determining how we measure time, because of the way Earth is both rotating and orbiting the Sun, and doing so at slightly different speeds.

What is used in making atomic clocks that lose one second every 300 years?
Perhaps caesium (cesium) is the answer.
How can international time-standard clocks be regulated by atomic vibrations that are accurate to 1 second on 80 million years?
The best of these are currently the 'cesium fountain' atomic clocks in which the cesium atoms, and their atomic spectral emissions, is cooled to close to absolute zero (to minimise thermal effects). These can reach stability of the order of 3 parts in 10(-16). The atomic clock at NIST in the US is of this type. (And in UK, and France etc.) Which is equivalent to an uncertainty of 1 second in 100 million years.
What kind of clock offers the most precise?
Atomic clocks are the most accurate clocks that are available to the general public. To date, the most accurate clock made is the so-called quantum logic clock, which is accurate to about one second in 3.7 billion years.
Why were clocks put back by one second on 1 July 1983?
One second. Mistake sorry Answer is: It was a leap second
There are 2 clocks The red clock is broken and doesn't run at all The blue clock loses one second every 1 second Which clock would be more likely to give the correct time?
Staying at a fixed time position, both the red and blue clocks will show the correct time twice a day (every 24 hours). So both clocks are equally likely to give the correct time.
What element is used to make atomic clocks?
The atom of the isotope caesium 133; the definition of second in SI is based on this atom.
Used in the making of atomic clocks that lose one second every 300 years?
Cesium
Who invented the atomic clock?
The first atomic clock was invented in 1948 by the US Bureau of Standards.The first practical atomic clock was invented by English physicist Louis Essen in the 1955.Atomic clocks use the energy changes that take place in atoms to keep track of time. Atomic clocks are so accurate that they lose or gain no more than 1 second once every 2 or 3 million years.The most accurate, modern-day atomic clocks will neither lose nor gain a second in 168 million years.
What is used in making atomic clocks that lose one second every 300 years?
Perhaps caesium (cesium) is the answer.
What reason the atomic clocks used in global positioning system?
For the simple reason that atomic clocks are highly accurate - usually only gaining or losing one second over thousands of years. High accuracy is vital in GPS systems - otherwise the maps would be out of alignment as you travelled. As an example - One of the most recent atomic clocks constructed in 2010 is reckoned to only gain or lose less than a second in over a billion years !

How much do telemarketers make an hour?
In 1967, an atomic standard was adopted for second, the SI unit of time. One standard second is defined as the time taken for 9 192 631 770 periods of the radiation corresponding to unperturbed transition between hyperfine levels of the ground state of cesium - 133 atom. Atomic clocks are based on this. In atomic clocks , an error of one second occurs only in 5000 years. From 60 sec is 1 min from this 60 minutes is hour

On the 1st of July clocks were put back by one?
clocks were put back by one second
One of the most metallic metals named for its sky blue spectral lines atomic clocks using this element are accurate to 5 seconds in 300 years or 1 second in 60 years?
