How long is 100 seconds
What if a minute had 100 seconds?
If 100 seconds would make 1 minute, then a day would be 86400/100 = 864 minutes, and if 100 minutes would make 1 hour, then a day would be 86400/10000 = 8.64 hours.
How long is 1 minute exactly?
60 seconds
The minute is a unit of time usually equal to 160 (the first sexagesimal fraction) of an hour, or 60 seconds.
What is the seconds of 1 minute?
There are 60 seconds in 1 minute. In other words, a second is 160 of a minute. The second is called the base unit of time.
What is longer 1 second or 1 minute?
The answer, simply, is that a second is 1/60th of a minute, or 1/3600th of an hour.
How long is a second?
Since 1967, the second has been defined as exactly “the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom” (at a temperature of 0 K and at mean sea level).
Who created minutes?
Who decided on these time divisions? THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.
Why second is called second?
First the hour was divided into small (“minute”) units (Latin: “pars minuta”). Later on, even more precision became necessary, so a second division into “seconds” was introduced (Latin: “pars minuta secunda”).
How was seconds invented?
Seconds were once derived by dividing astronomical events into smaller parts, with the International System of Units (SI) at one time defining the second as a fraction of the mean solar day and later relating it to the tropical year.

How 1 second is defined?
The second is defined by taking the fixed numerical value of the caesium frequency ∆ν, the unperturbed ground-state hyperfine transition frequency of the caesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s−1. The wording of the definition was updated in 2019.
How long is half a second?
1/120 of a minute of time.
How long is a day on Pluto?
6.4 Earth days
Pluto’s day is 6.4 Earth days long.
How is 1 hour in space 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
How long is a light-year?
365.25 days
As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days).
How long is 1 year in space?
**One year in space would be 365 days /1 year on earth…..
How long is 1 year on the Moon?
Since each lunation is approximately 291⁄2 days, it is common for the months of a lunar calendar to alternate between 29 and 30 days. Since the period of 12 such lunations, a lunar year, is 354 days, 8 hours, 48 minutes, 34 seconds (354.36707 days), purely lunar calendars are 11 to 12 days shorter than the solar year.
How long is 1 hour in space?
One hour on Earth is 0.0026 seconds in space.
How much is a ticket to Mars?
Elon Musk: A Round-Trip Ticket to Mars Will Cost Just $100,000.
Do people age in space?
Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.
How much do astronauts get paid?
The middle pay grades for astronauts are G-12 and G-13; each grade is divided into 10 steps, which depend on seniority and/or performance. The middle pay for a G-12 employee is $73,090 to $75,240, and the middle pay for a G-13 employee is $86,911 to $89,467. That means the average astronaut’s pay is $81,177.
Why was NASA shut down?
All of these factors — high costs, slow turnaround, few customers, and a vehicle (and agency) that had major safety problems — combined to make the Bush administration realize it was time for the Space Shuttle Program to retire.
