How do you calculate related rates?
Space and AstronomyHow do you find related rates? Draw a picture of the physical situation. Don’t stare at a blank piece of paper; instead, sketch the situation for yourself. … Write an equation that relates the quantities of interest. … Take the derivative with respect to time of both sides of your equation. … Solve for the
Can square roots be rational?
Space and AstronomyMany square roots are irrational numbers, meaning there is no rational number equivalent. What makes a square root rational? Remember what irrational means- we cannot express the number as a ratio of two other numbers. √6 just continues on and on forever, which is what makes it irrational. We have expressed √49 as the ratio
How much space debris is there?
Space and AstronomyThere are over 20,000 known and tracked pieces of space debris orbiting Earth, each one traveling at about 15,000 mph (24,000 km/h). They pose a risk to future space missions, and nobody is bothering to clean it up. How much space junk is there 2021? As of 2021, the United States Space Surveillance Network was
Where did Edwin Hubble make his discovery?
Space and AstronomyEdwin Hubble’s arrival at Mount Wilson Observatory, California, in 1919 coincided roughly with the completion of the 100-inch (2.5 m) Hooker Telescope, then the world’s largest. At that time, the prevailing view of the cosmos was that the universe consisted entirely of the Milky Way Galaxy. When did Edwin Hubble make his discovery? On December
What are dimensions used for?
Space and AstronomyIn mathematics and science, dimension is used in describing spatial concepts such as points, lines, and solids. Where are dimensions used? Dimensions can be used to measure position too. The distance to a position from a starting place can be measured in the length, width and height directions. These distances are a measure of the
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
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
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 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
