What are the numbers before seconds?
Less than one second
| Multiple of a second | Unit | Symbol |
|---|---|---|
| 10−9 | 1 nanosecond | ns |
| 10−6 | 1 microsecond | µs |
| 10−3 | 1 millisecond | ms |
| 10−2 | 1 centisecond | cs |
What is lower than seconds?
The units smaller than a second are: Milliseconds: 10-3 s. Microseconds: 10-6 s. Nanoseconds: 10-9 s. Picoseconds: 1012 s.
What is 0.01 of a second called?
Centisecond, while valid, is an extremely rarely used unit, as is hectometer or decaliter. You either measure “hundredths of second” or tens of milliseconds. In engineering, milliseconds are preferable. In sports hundredths are the defacto standard; as Jim said: fourteen and five hundredths of a second.
How fast is a second?
The answer, simply, is that a second is 1/60th of a minute, or 1/3600th of an hour.
How is the length of a second determined?
The second is defined as being equal to the time duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the fundamental unperturbed ground-state of the caesium-133 atom. Multiples of seconds are usually counted in hours and minutes.
What is a shake in time?
A shake is an informal metric unit of time equal to 10 nanoseconds, or 10−8 seconds. It has applications in nuclear physics, helping to conveniently express the timing of various events in a nuclear reaction, especially neutron reactions.
Is it 0.1 seconds or second?
When we say 1 second, it is singular. When we say 0.1 seconds, it is plural.: Showerthoughts.
How many significant figures should a second order reaction have?
Your response should have three significant figures. If a second order reaction has an initial concentration of 4.75 M and a concentration of 3.15 M after 17.5 minutes, what is the rate constant k for the reaction? Your answer should have 3 significant figures (report the answer in scientific notation).
Which is the correct notation for multiples of seconds?
Multiples of seconds are usually expressed as minutes and seconds, or hours, minutes and seconds of clock time, separated by colons, such as 11:23:24, or 45:23 (the latter notation can give rise to ambiguity, because the same notation is used to denote hours and minutes).
Who was the first person to calculate time in seconds?
It was the first clock that could accurately keep time in seconds. By the 1730s, 80 years later, John Harrison’s maritime chronometers could keep time accurate to within one second in 100 days. In 1832, Gauss proposed using the second as the base unit of time in his millimeter-milligram-second system of units.
What are the units of K for a zero order reaction?
The units of k for a zero-order reaction are M/s, the units of k for a first-order reaction are 1/s, and the units of k for a second-order reaction are 1/ (M·s). Created by Yuki Jung. Google Classroom Facebook Twitter
