A planar surface is a flat, two-dimensional surface that extends infinitely in all directions within its plane. In mathematics and geometry, a plane is defined by a flat surface that is characterized by two dimensions—length and width—while having no depth. Planar surfaces can be represented in various ways, such as through geometric shapes (like rectangles or triangles), equations (such as the equation of a plane in 3D space), or in computer graphics as polygons.

It is an odd number and can be expressed in various ways, such as in binary (1110111), hexadecimal (77), and as a sum of prime numbers. In terms of mathematics, 119 is not a prime number since it can be factored into 7 and 17 (119 = 7 × 17). It is also notable for being a palindrome in certain bases.

The 120th meridian east is a line of longitude that is 120 degrees east of the Prime Meridian, which is the line of longitude defined as 0 degrees. It runs from the North Pole to the South Pole and divides the eastern and western hemispheres.

The 122nd meridian west is a line of longitude located 122 degrees west of the Prime Meridian, which runs through Greenwich, England. This meridian extends from the North Pole to the South Pole and passes through several regions in North America. In the United States, the 122nd meridian west runs through parts of Alaska, Canada, and the western continental U.S., including states such as Washington and California.

The 123rd meridian west is a line of longitude that is located 123 degrees west of the Prime Meridian, which runs through Greenwich, England. It is part of the global coordinate system used for navigation and mapping. This meridian runs from the North Pole to the South Pole, passing through several regions in North America. In the United States, it traverses parts of the states of Washington, Oregon, and California.

The number 126 is an integer that follows 125 and precedes 127. It can be broken down into its prime factors as \(2 \times 3^2 \times 7\). The number is considered an even number and can be expressed in various numeral systems (e.g., binary: 1111110, hexadecimal: 7E). In terms of mathematics: - It is a composite number, as it has factors other than 1 and itself.

Extended ML (EML) is an extension of the Standard ML programming language designed to enhance its capabilities for specific applications, particularly in the context of theorem proving and formal verification. It incorporates features that facilitate more complex data manipulation and reasoning about programs. Extended ML adds to the original features of Standard ML by providing: 1. **Type Extensions**: It allows for more expressive type systems, supporting extensions necessary for representing mathematical concepts in a more straightforward way.

The 131st meridian west is a line of longitude located 131 degrees west of the Prime Meridian, which is defined as 0 degrees longitude and runs through Greenwich, England. The 131st meridian west travels from the North Pole to the South Pole, passing through several regions. In the United States, it crosses through states like Alaska, and it also goes through parts of Canada and Mexico.

The 141st meridian west is a line of longitude that is 141 degrees west of the Prime Meridian, which runs through Greenwich, England. This meridian runs from the North Pole to the South Pole, passing through parts of the northern and southern hemispheres. In North America, the 141st meridian west roughly forms part of the border between the U.S. state of Alaska and Canada. Further south, it crosses portions of the Pacific Ocean.

The term "145 mm artillery" typically refers to a type of artillery piece that fires shells with a diameter of 145 millimeters. This caliber is less common than other standard artillery calibers such as 105 mm, 155 mm, or larger systems. Typically, artillery pieces can include towed howitzers, self-propelled guns, and mortars, among others.

The 148th meridian east is a line of longitude that is located 148 degrees east of the Prime Meridian, which runs through Greenwich, England. This meridian runs from the North Pole to the South Pole and is used in geographical coordinate systems to determine locations on the Earth. The 148th meridian east passes through several countries and territories, primarily in the Pacific region. It crosses parts of Russia, specifically in the Kuril Islands, and touches the northern parts of Japan.

The Weinberg angle, also known as the weak mixing angle or the electroweak mixing angle, is a fundamental parameter in the electroweak theory, a critical component of the Standard Model of particle physics. It quantifies the mixing between the electromagnetic force and the weak nuclear force, which are unified at high energies. Specifically, the Weinberg angle (\(\theta_W\)) determines the relationship between the electric charge and the weak isospin of particles.

Unix emulation software refers to programs that allow non-Unix operating systems to run applications or commands that are natively intended for Unix-based systems. This can facilitate compatibility and development across different platforms by providing an environment that mimics the behavior and functionality of a Unix operating system. Here are some key aspects of Unix emulation software: 1. **Compatibility Layer**: It acts as a compatibility layer between the Unix applications and the host operating system.

A hydraulic fuse is a safety device used in hydraulic systems to prevent the uncontrolled release of hydraulic fluid or the loss of system pressure. It functions similarly to an electrical fuse, but instead of protecting electrical circuits, it safeguards hydraulic circuits by detecting the rate of fluid flow and pressure. The primary purpose of a hydraulic fuse is to ensure that, in the event of a hose rupture or significant leak, the flow of fluid is quickly interrupted.

An acyclic model generally refers to a system or structure that does not contain cycles. In various contexts, this term can have different meanings, but it is commonly used in the fields of computer science, mathematics, and data structures. Here are a few specific contexts in which an acyclic model might be referenced: 1. **Graph Theory**: In graph theory, an acyclic graph is a graph that does not contain any cycles.
