What is an Astronomical second?
An astronomical second is a unit of time defined based on the Earth's rotation. It is equal to 1/86,400 of a mean solar day, or about 0.9973 seconds. It is used in astronomy and celestial navigation for precise time measurements.
Geological time is divided into units based upon types of what?
Geological time is typically divided into units based on types of rock layers, fossils, and major events in Earth's history. The primary units of geological time are eons, eras, periods, epochs, and ages. These divisions help scientists organize and study the Earth's long history.
UTCs are comprised of but not limited to which of the following?
UTCs (Coordinated Universal Time) are comprised of atomic time and astronomical time. Atomic time is based on highly precise atomic clocks, while astronomical time is based on the rotation of the Earth. Other elements involved in UTCs include leap seconds to account for the slowing of the Earth's rotation and international agreements to ensure a common time reference worldwide.
SI is based on?
The International System of Units (SI) is based on seven base units: the meter for length, kilogram for mass, second for time, ampere for electric current, kelvin for temperature, mole for amount of substance, and candela for luminous intensity. These base units are used to derive other units for quantities such as area, volume, and velocity.
What is the relationship of the speed of revolution of a planetary object to the position of the planetary object in the solar system?
Kepler's third law says that the time of one revolution round the Sun is proportional to the distance raised to the power 3/2.That means that a planet at a distance of 4 astronomical units would have a rotation period of 8 years. At 9 astronomical units it would take 27 years.
What is 84 years in astronomical units?
A year is a unit of time. An astronomical unit is a unit of distance. The two units are therefore incompatible.
Day and year as units of time based on motion of what?
the earth.
Which type of depreciation is not based on pasage of time?
Units of production

How many Astronomical Units from the sun to the moon?
If you want a precise measurement at a particular time, it depends. An astronomical unit is defined as the mean distance from sun to Earth. So the Sun-Moon AU measurement would vary depending on where the earth is in it's orbit (i.e. nearer or farther than the average distance) and where the moon is in its rotation around the Earth. But the mean distance over time would still be one AU.

What are the four units the Finance Administration Section may staff?
The four units the Finance Administration may staff are Procurement Units, Cost Units, Time Units, and Compensation/Claims Units. The are created based on need.
The day and the year as units of time are based upon motions of?
Calanders are based on the revolution of the earth around the sun.

What is an astronomical year?
An astronomical year is a unit of time, the amount of time it takes for the Earth to pass around the sun.
What is 9 grams in ounces?
Here's a cool tip, you can use Google as a conversion tool. In your search field, type "9 ounces to grams", you will have your answer. This works for linear, area, volume and time units. I use it all the time. eg. "987,644 astronomical units to light years" "98 degrees Fahrenheit to degrees Celsius" "75 centimeters to inches"
