Attosecond
A nanosecond comes before an attosecond and before a nano second is a millisecond and before that is a second
0.4 is smaller than 0.404
0.01 is smaller than 0.2
1.0 is bigger than 0.1.
Attosecond
Split second, milli, micro, nano, pico, femto, attosecond etc.
An attosecond is an SI unit of time equal to 10 ^ -18 seconds.
Examples: -- picosecond -- femtosecond -- yoctosecond -- attosecond
A nanosecond comes before an attosecond and before a nano second is a millisecond and before that is a second
An attosecond is 1x10-18 seconds
Another attosecond; that's how time works.The metric prefix "atto" means 10^-18. The next smaller prefix, which may be what you meant to ask, would be "zepto" for 10^-21, followed by "yocto" for 10^-24. No smaller prefixes are formally defined, but a "Planck time" is about 5 x 10^-44 seconds, and is believed to be the smallest physically meaningful unit of time.
An attosecond is one quintillionth (10 to the power of minus 18) of a second. As of 2006, the smallest unit of time that was directly measured was on the order of 1 attosecond (10−18 s), or about 1026 Planck times. In physics, the Planck time, (tP), is the unit of time in the system of natural units known as Planck units. It is the time required for light to travel, in a vacuum, a distance of 1 Planck length. The unit is named after Max Planck, who was the first to propose it.
A newton is larger than a dyne and smaller than a kilogram-force.
it can get smaller than an atom
Ofcourse sea is smaller than an ocean
0.4 is smaller than 0.404
