Time

The division of a minute into 60 seconds is believed to originate from ancient Mesopotamia, where they used a base 60 numbering system. This system was later adopted by the Babylonians and eventually spread to other cultures. The number 60 is easily divisible by many numbers, making it a practical choice for time measurement.

You looked (though not too directly) at the sun. Later you used arrangements of rocks and calculated time by shadows, and later still, sundials became popular. The peasants simply got up at daylight and went to bed when the sun had gone well down, to save on candles. In between they tended crops and cattle at the appropriate time. Crops and cattle tend to let you know if you're getting it wrong; crops wither and cows and pigs and goats and so on wake you up in the night if they're not comfortable. But only a very bad farmer would get it wrong, and didn't need a clock to get it right. Flower clocks were created as a novelty, but still told the time. The first mechanical clocks were a novelty, and for the wealthy, who in any case had servants to take note of when the sun rose.

light gates are simple optical circuits that have an opening between an emitter and receiver. If the path between the two is interrupted, a signal is sent to a computer or other data recorder.

light gates are typically used for timing and detection.

I didn't know that this is standard practice, but it certainly makes sense ...

In modern clocks, the pendulum rod is some solid material such as metal or wood. In either case, long-term higher temperature would cause the rod to expand slightly, which in turn would slightly lengthen the pendulum's period. Doesn't have to be much, but the clock definitely slows down, and loses time over an extended period.

In order to compensate for the lengthening of the pendulum and slowing of the clock when the temperature rises, the rod should be slightly shortened.

21,600 seconds.

Time and distance are related through the concept of speed, which is the measure of how quickly an object travels a certain distance over a specific period of time. The formula for speed is Distance = Speed × Time, which shows that the distance covered is directly proportional to the speed at which an object moves and the time taken to reach that distance.

Vibrations a second are measured in Hertz.

There is no such unit as a billisecond. A billionth of a second (10-9 s) is called a nanosecond.

There is currently no scientific evidence to support the existence of time travelers. The concept of time travel remains theoretical and has not been proven to be possible within the laws of physics as we currently understand them.

Micro means 0.000001, a century is 100 years. Therefore a microcentury is 0.0001 years, or 0.0365.25 days or 0.8766 hours or 25.596 minutes.

Well there are 365 days in a year (366 in a leap year) so say 365.25 to even it out.

1000000/365.25 = 2737.8507871321013004791238877481 years

and there are 12 months in each year.

2737.8507871321013004791238877481 * 12 = 32854.209445585215605749486652977 months

or There are an average of 30.4375 days per month. 1,000,000 divided by 30.4375 will get you the same number.

There are 2 hours in 7200 seconds.

No such conversion is possible; Seconds measure time, Litres measure volume (1 US gallon = 3.78 litres, 1 UK gallon = 4.55 litres).

There are 166.65 minutes in 9999 seconds.

Millisecond blackouts can happen due to brief disruptions in the power supply or electrical signal, causing a temporary loss of information or data. These micro-outages are usually very short and may go unnoticed by most devices, but they can occasionally affect sensitive equipment or systems that are highly dependent on continuous power.

There are 13 minutes and twenty seconds in 800 seconds. There are 60 seconds in one minute, so take 800 and divide by 60, getting 13.3333. (One third of a minute is 20 seconds)

1000 Miliseconds = 1 Second.

0.001 Seconds in a Milisecond.

There are 2.22 hours in 8000 seconds.

0.3 cm

a) one trillionth of a second= 1.0x10^-12

b) light travels at = 3x10^8 meters per second

b/a= 0.0003 meters = 0.3 cm

actually

0.03cm or 0.3mm or 300µm

One trillionth of a second is equal to a picosecond, which is a unit of time commonly used in scientific measurements where very small time intervals are involved. Closer to a picosecond is a femtosecond, equal to one quadrillionth of a second.

one short ton = 2000 pounds - one long ton = 2200 pounds

PS is a short form for Pico seconds ( Pronounced : paecoh)

1ps = 10^ (-12) that is 10 raised to the power of -12. Very small unit.

ns is a short form for Nano second .

1ns = 10^ (-9) that is 10 raised to the power of -9.

Now logically 1ns is greater than 1ps as picoseconds has more decimal places. Analogous to 0.1 being greater than 0.0001

Now to your questions.

1351ps = 1.351 ns (just decimal conversion)

Hence 1.351 is greater than 1.2 ns
