Does the relation represent a function?
Space and AstronomyWRITING IN MATH How can you determine whether a relation represents a function? SOLUTION: A relation is a function if each element of the domain is paired with exactly one element of the range. If given a graph, this means that it must pass the vertical line test. How do you know if the relation

What causes an accretion disk?
Space and AstronomyThe accretion disk forms when diffuse material is attracted to a massive central body, like a black hole. The flattened shape of the accretion disk is due to angular momentum, which dictates the particles’ motion as they rotate around the black hole. How does an accretion disk form? Black holes are formed when massive stars

What is a terminal point?
Space and AstronomyWhat is the terminal point in math? To find the terminal point on the unit circle, start at (1,0), measure the angle in degree or radian on the circle (move counter clockwise if the angle is positive and clockwise if the angle is negative.) The coordinate of the endpoint is called the terminal point. How

What is a comet and example?
Space and AstronomyThe definition of a comet is a celestial body that moves around the sun, and as it goes near the sun it forms a vapor trail of dust and gas that streams after it. An example of comet is Haley’s. What is comet explain? Comets are frozen leftovers from the formation of the solar system

What percent of spearmint oil is Carvone?
Space and AstronomyA total of 63 chemical constituents were identified in spearmint oil using GC/MS, constituting 99.9% of the total identified compounds. The main components were carvone (40.8% ± 1.23%) and limonene (20.8% ± 1.12%). Does spearmint have carvone? Carvone is a member of a family of chemicals called terpenoids. Carvone is found naturally in many essential

How long is a comet’s tail?
Space and AstronomyThe length of a comet’s tail depends on many factors, including how close the comet passes to the Sun. A typical tail might stretch a few hundred thousand miles or longer. And the longest tail ever recorded stretched about 350 million miles — a long streamer that made the comet a comet. Are comets long
