In the branch of algebra called group theory, they are called equivalent classes or residual classes. They are generated with the fixed distance as the basis of the modulo relationship.
i think its a line graph
Is that the 'scale'?
It could be a ruler. Just a number line.
A number line or, in 2 or more dimensions a grid.
scale???????
The scale
an ellipse.
However unsure as I may be sir/ma'am, I believe the answer is a scale.
because what word is series of numbers placed at fixed distances on the scale
Yes, in atomic theory, electrons occupy fixed distances from the nucleus, often described as specific energy levels or shells. Each shell corresponds to a particular energy state and can hold a set number of electrons. While these distances are not fixed in a physical sense, as electrons exist in probabilistic orbitals, they represent regions where electrons are likely to be found at certain energy levels. Thus, the concept of fixed distances is more about energy levels than absolute positions.
The set of all points in a plane for which the sum of the distances to two fixed points equals a certain constant. - APEX
The term that best describes the set of all points in a plane for which the sum of the distances to two fixed points equals a certain constant is called an "ellipse." In this geometric shape, the two fixed points are known as the foci, and the constant represents the total distance that remains constant for all points on the ellipse.
