The NIST-F1 Cesium fountain clock is in Colorado. It is the standard for primary time and frequency in measuring time.

The NIST laboratories in Boulder, Colorado, developed the cesium fountain atomic clock NIST-F1, which serves as the country's primary time and frequency standard. NIST-F1 is a member of the global network of atomic clocks that establishes Coordinated Universal Time (UTC), the recognized global time.

The NIST-F1 is known as a fountain clock because it measures frequency and time intervals by using the atoms' fountain-like movement. Atomic clocks are the most precise means of measuring time intervals, or the amount of time that separates two events.

Atoms in the clocks leap from one energy level to another due to the precise frequency at which these clocks emit electromagnetic radiation, such as microwaves.

2 Gravity (hydrostatic) and pressure (thermal) create an equilibrium during star

kondaur [170]

Answer:

Imbalance occur when the hydrogen of the star's core used up.

Explanation:

Both gravity (hydrostatic) and pressure (thermal) create an equilibrium state during star formation. A star is in the state of hydrostatic equilibrium when the pressure that is created due to core burning is in balance with the force of gravity. These two will be in equilibrium when the outer push of core is in equal amount to the inward push of gravity. When the hydrogen that is present in the star's core has been used up, burning stops, which leads to the imbalance of gravity and pressure. This imbalance the star which undergo significant changes in its shape and structure..

The type of plate boundary referred here is defined as an ocean-Continent Convergent Plate Boundary.

<h3>What is an ocean-continent convergent plate boundary?</h3>

An ocean-continent convergent boundary is a limit in which the oceanic plate is forced underneath the continental plate.

This type of boundary occurs when an oceanic lithospheric plate crashes against to a continental plate.

In conclusion, the type of plate boundary here is defined as an ocean-Continent Convergent Plate Boundary.
