Since the clock produces 45 useful unites energy units for every 100 unites of energy that it uses, than it turns out that the efficiency of the clock is 45 percent.
The formula to calculate efficiency is: output divided by input and the result should be multiplied by one hundred or output/input x 100. In this case, we will say 45/100 which gives us .45 this has to be multiplied by 100 to obtain the percentage. .45 multiplied by 100 is 45%. That is the reason behind our answer.
The First GPS was made available to the public this year as earlier it was under the control of the U.S military and used for strategic purposes. As they feared that giving it to the public could cause a potential loss or damage to the integrity of the country.
Originally developed by the military for surveillance and monitoring program it consisted of 24 satellite systems and each satellite transmitted unique signals that were decoded to compute the precise location of satellites.
