Line, Ray and segment
line segment
A line segment can grow into a three-dimensional object through a process called extrusion or revolution. In extrusion, the line segment can be extended along a path, creating a solid shape like a cylinder or prism. In revolution, rotating the line segment around an axis can form a three-dimensional object such as a sphere or cone. This transformation involves the addition of depth and surface area to the initial one-dimensional form.
Segment: The length of one side of an object only measuring the length of that individual side. For Example: Line Segment AB measures 2 in.
Its physical dimentions
For any segment base address, segment first physical address will have 0 in the least significant position in hexadecimal format. Let say, our Segment base =0x1234, and we calculate segment first physical address as 0x12340
An object's size is a physical property of the object.
No, "Metropolis" is an abstract noun because it refers to a concept or idea rather than a physical object.
Two dimensions object
Yes, detention is an abstract noun because it refers to a concept or an idea rather than a physical object.
Yes, "justice" is an abstract noun. It represents a concept or idea rather than a physical object.
"Unhappiness" is a abstract noun, as it represents a non-physical concept or idea rather than a tangible object.
A physical possession is a tangible object that you own. Meaning that you actually own the object, can prove it and show it to others, as opposed to an idea or thought that you say is yours, but cannot claim ownership. IE: an invention that you do not own a patent on (this is considered intellectual property.)
An edge
Truth is an abstract noun, as it represents a concept or idea rather than a physical object that can be counted.
No, "expert" is an abstract noun because it refers to a concept or idea rather than a physical object that can be touched or seen.
