An OROCA (Obstacle Clearance Altitude) is a minimum altitude that provides a buffer or safety margin above obstacles within a specified area. This buffer is designed to ensure that aircraft can safely fly over terrain and man-made obstacles, such as buildings or towers, without the risk of collision. The specific buffer provided by an OROCA will vary depending on the terrain and the obstacles in the area, with larger buffers typically required in mountainous regions. In general, an OROCA is designed to provide a safe and reliable minimum altitude for aircraft operating in both mountainous and nonmountainous areas.

An algorithm that keeps recently used items near the top of the cache and when the cache limit has been reached, items less accessed are removed
This algorithm is called a "Least Recently Used" (LRU) algorithm. It ensures that the items that have been accessed recently are kept at the top of the cache, making them easier and faster to retrieve.
Once the cache limit has been reached, the algorithm removes the items that have been accessed the least, freeing up space for new items to be added. The LRU algorithm is commonly used in computer systems to manage memory and improve system performance.
What is the least recently used algorithm?
Least Recently Used (LRU) is a common caching strategy. It defines the policy to evict elements from the cache to make room for new elements when the cache is full, meaning it discards the least recently used items first. Let's take an example of a cache that has a capacity of 4 elements.

The maximum stress that exists at the p of a crack is dependent on:
The maximum stress that exists at the tip of a crack, often referred to as the "stress intensity factor" or "K-factor," is dependent on several factors. These factors include:
Applied load: The magnitude of the applied load, which can include tensile, compressive, or bending loads, affects the stress intensity factor at the crack tip. Higher applied loads result in higher stress intensity factors. Crack size: The size of the crack, typically represented by the crack length, also affects the stress intensity factor. Larger cracks result in higher stress intensity factors.
Material properties: The material properties of the material in which the crack is present, such as its fracture toughness and elastic modulus, also influence the stress intensity factor. Materials with higher fracture toughness and lower elastic modulus tend to exhibit lower stress intensity factors.
Crack shape: The shape of the crack, such as its geometry and orientation, can also affect the stress intensity factor. Different crack shapes result in different stress intensity factors.

The color of light an LED produces is determined by the energy required for _______ to cross the band gap
The color of light produced by an LED is determined by the energy required for electrons to cross the band gap.
The band gap is the energy difference between the valence band (where the electrons are bound to atoms) and the conduction band (where electrons are free to move). When an electric current is applied to an LED, electrons are excited from the valence band to the conduction band, and as they fall back into the valence band, they release energy in the form of light. The wavelength (and therefore the color) of the light emitted by the LED depends on the energy of the band gap, which in turn depends on the specific materials used in the LED. Different materials and doping levels can be used to create LEDs that emit different colors of light.
Therefore, the color of light produced by an LED is determined by the energy required for electrons to cross the band gap.

When the batt switch is in normal where does emer bus get power
When the battery (batt) switch is in the normal position, the emergency (emer) bus gets power from the main power distribution system through the automatic transfer switch.
Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
The switch detects a loss of power from the main source and automatically transfers the power supply to the battery backup, ensuring the emergency bus continues to receive power.
