What is are the major differences between a meter stick and a vernier caliper?
Space and AstronomyUnlike a meter stick, the vernier caliper allows the fractional part of the smallest division to be accurately determined, not merely estimated. The vernier consists of a main scale engraved on a fixed ruler and an auxiliary scale engraved on a moveable jaw (see Figure 3). What is the main difference between vernier caliper and

What is a square root expression?
Space and AstronomyA square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand. √a. To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of

Why does a curved mirror create a distorted image?
Space and AstronomyFor a concave mirror the skewers point toward each other, and the reflected light rays spread out less. The reflection of an object close to the mirror is bigger and looks farther away. What would happen to an image if the mirror is curved? Reflection from a Concave Mirror The image is real light rays

What is the correct order of star colors from hottest to coolest?
Space and AstronomyRed stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all. What is the correct order of stars from hottest to coolest? The seven main types are M, K, G, F, A, B and O. M stars are

Why do coronal mass ejections occur?
Space and AstronomyBottom line: Coronal mass ejections – also knowns as CMEs – are powerful eruptions on the sun’s surface. Caused by instabilities in the sun’s magnetic field, they can launch a billion tons of superheated gas into space. Most drift harmlessly across the solar system, but occasionally one is aimed at Earth. How is CME formed?

What is axes Matplotlib?
Space and AstronomyAxes object is the region of the image with the data space. A given figure can contain many Axes, but a given Axes object can only be in one Figure. The Axes contains two (or three in the case of 3D) Axis objects. The Axes class and its member functions are the primary entry point

How do you do relationships in math?
Space and AstronomyRelations can be displayed in multiple ways: Table: the x-values and y-values are listed in separate columns; each row represents an ordered pair. Mapping: shows the domain and range as separate clusters of values. Graph: each ordered pair is plotted as a point and can be used to show the relationships between values. How do

Are any two points coplanar?
Space and AstronomyCoplanar points: A group of points that lie in the same plane are coplanar. Any two or three points are always coplanar. Four or more points might or might not be coplanar. How do you know if two points are coplanar? Video quote: Well the points are going to be coplanar are going to be

Is concave up or down?
Space and AstronomyA function is concave up (or convex) if it bends upwards. A function is concave down (or just concave) if it bends downwards. I personally would always mix these two up. How do you know if concave up or down? A graph is said to be concave up at a point if the tangent line

What is a lofted surface?
Space and AstronomyLoft Surfaces are surfaces generated by multiple 3D Curves or existing edges creating a smooth tangency between the selected curves. Match Points are created between each selection denoting the orientation and path of the loft surface. How do you make a lofted surface? To create a lofted surface: Create a plane for each profile section
