What is a cross section of a 3d figure?
Space and AstronomyA cross-section is a plane section that is a section of a three-dimensional object that is parallel to one of its planes of symmetry or perpendicular to one of its lines of symmetry. Describe shapes formed by cross-sections (square, rectangle, triangle, etc). What is the cross section of a 3D object? A cross section is

How is Star magnitude measured?
Space and AstronomyOne magnitude is defined as a ratio of brightness of 2.512 times; e.g., a star of magnitude 5.0 is 2.512 times as bright as one of magnitude 6.0. Thus, a difference of five magnitudes corresponds to a brightness ratio of 100 to 1. What is a star magnitude scale? The magnitude scale is a logarithmic

Is the square root of a negative number imaginary?
Space and AstronomyThe square root of a negative number does not exist among the set of Real Numbers. really meant. In an effort to address this problem, mathematicians “created” a new number, i, which was referred to as an “imaginary number”, since it was not in the set of “Real Numbers”. Is the square root of a

What are concentric triangles?
Space and AstronomyIn geometry, two or more objects are said to be concentric, coaxal, or coaxial when they share the same center or axis. Circles, regular polygons and regular polyhedra, and spheres may be concentric to one another (sharing the same center point), as may cylinders (sharing the same central axis). What is a concentric in geometry?

What comes first in a glide reflection?
Space and AstronomyA glide reflection is a composition of transformations.In a glide reflection, a translation is first performed on the figure, then it is reflected over a line. Therefore, the only required information is the translation rule and a line to reflect over. How do you know if its a glide reflection? A glide reflection is a

What is a visibility symbol in UML?
Space and AstronomyIn object-oriented design, there is a notation of visibility for attributes and operations. UML identifies four types of visibility: public, protected, private, and package. The +, -, # and ~ symbols before an attribute and operation name in a class denote the visibility of the attribute and operation. Which symbol is used for public visibility?

What are spreading calipers used for?
Space and AstronomySmall Spreading Caliper (pointed ends) The GPM Small Spreading Caliper with pointed ends provides accurate measurement of short distances between two points, where one or both points may not be on a flat surface. This caliper is most commonly used for craniometry and cephalometry. How do you read a spreading brake caliper? Video quote: The

What is a division number model?
Space and AstronomyA repeated subtraction or measurement model of division is a situation where the dividend represents. the number of objects and the divisor represents the size of each group. For example, in the problem. 12÷4, the 12 stands for the number of objects and the 4 stands for the size of each group. How do you

What is discrete structure function?
Space and AstronomyAdvertisements. A Function assigns to each element of a set, exactly one element of a related set. Functions find their application in various fields like representation of the computational complexity of algorithms, counting objects, study of sequences and strings, to name a few. What is meant by discrete structure? discrete structure A set of discrete

What is a non congruent shape?
Space and Astronomythe sides, and noncongruent means “not congruent,” that is, not the same shape. (Shapes that are reflected and rotated and translated copies of each other are congruent shapes.) So we want triangles that look fundamentally different. What is a non example of congruent? Video quote: So for example this shape is congruent to this shape
