What properties are preserved under a translation?
Space and AstronomyWe found that translations have the following three properties: line segments are taken to line segments of the same length; angles are taken to angles of the same measure; and. lines are taken to lines and parallel lines are taken to parallel lines. What properties are preserved by translations? Properties preserved under a translation from

What is the life cycle of a low mass star?
Space and AstronomyFor low-mass stars (left hand side), after the helium has fused into carbon, the core collapses again. As the core collapses, the outer layers of the star are expelled. A planetary nebula is formed by the outer layers. The core remains as a white dwarf and eventually cools to become a black dwarf. What are

How do you find the midpoint of a centroid?
Space and AstronomyWe know that the midpoint of the line segment joining two points has coordinates equal to half of the sum of the corresponding coordinates of the two points while the coordinate of the centroid is one third of the sum of the corresponding coordinates of the vertices of a triangle. What is the formula to

How do you identify a factor?
Space and AstronomyWhat does it mean to identify a factor? “Factors” are the numbers you multiply to get another number. For instance, factors of 15 are 3 and 5, because 3×5 = 15. How do you find factors quickly? Video quote: I want to find the factor of number 6. The first number which will divide number

How hot is an accretion disk?
Space and AstronomyThe maximum temperature in an accretion disk around a supermassive black hole a hundred times the mass of our sun will be around one million Kelvin and for the disk around a stellar black hole, it can be up to a factor hundred higher. How hot can an accretion disk get? Theory predicts that the

How do you write odd numbers in set builder notation?
Space and AstronomyHow do you write in set builder notation? Set Builder Notation Examples {y : y > 0} The set of all y such that y is greater than 0. Any value greater than 0. {y : y ≠ 15} The set of all y such that y is any number except 15. Any value except

How do you determine end behavior?
Space and AstronomyThe end behavior of a function f describes the behavior of the graph of the function at the “ends” of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the

What do brake caliper clips do?
Space and AstronomySome aftermarket brake companies are offering a solution that can be used on the caliper. The clips are designed to push the pad away from the rotor. This can keep the brakes cooler, reduce noise and extend the life of the pad. The clips fit between the pads and rotor and push the pads away

Do galaxies evolve from one type to another?
Space and AstronomyAlas, normal galaxies do not likely evolve directly from one type to another. Spirals don’t seem to be ellipticals with arms, nor do ellipticals appear to be spirals without arms. Do galaxies evolve? Scientists have long figured that galaxies evolve in a hierarchical structure, with mergers fueling growth, forcing star formation, and altering structure. Do
