What you see down a microscope?
Space and AstronomyA microscope is an instrument that is used to magnify small objects. Some microscopes can even be used to observe an object at the cellular level, allowing scientists to see the shape of a cell, its nucleus, mitochondria, and other organelles. What do you see under a microscope? Cheek cells. Cheek cells (more specifically, epithelial
How do you stretch or compress a function?
Space and AstronomyIn math terms, you can stretch or compress a function horizontally by multiplying x by some number before any other operations. To stretch the function, multiply by a fraction between 0 and 1. To compress the function, multiply by some number greater than 1. How do u stretch a function? We can also stretch and
Are adjacent angles always equal?
Space and AstronomyVertical angles are always congruent, which means that they are equal. Adjacent angles are angles that come out of the same vertex. Adjacent angles share a common ray and do not overlap. Are adjacent opposite angles equal? Adjacent angles may or may not be equal in measure. Opposite angles are always equal. Two adjacent angles
What is the eccentricity of a perfect circle?
Space and AstronomyScientists define zero “eccentricity” as a perfect circle and one “eccentricity” as no longer in orbit – Earth’s eccentricity is 0.0167, the most circular orbit of any planet in our solar system. How much eccentricity does a perfect circle have? The eccentricity ranges between one and zero. If the eccentricity is one, it will be

What color is a supergiant star?
Space and AstronomyRed supergiants have the largest radius of all known stars. They have low surface below 4,100 K. This is very cool for a star and makes them to shine with a red colour. The star Betelgeuse in the constellation of Orion is a red supergiant. What is the colour of supergiant stars? The color of
When was Comet invented?

Do you need permission to launch a rocket?
Space and AstronomyAny American citizen who wants to launch a rocket or other kind of spacecraft into orbit must obtain authorization from the FAA, as would any foreigner who launches within U.S. territory. The FAA regulates the commercial sector’s space activities by requiring parties to obtain launch and re-entry licenses. Can I launch my own rocket? Getting
What are the graphs of sine and cosine?
Space and AstronomyCharacteristics of Sine and Cosine Functions The domain of each function is ( − ∞ , ∞ ) and the range is. [ − 1 , 1 ] . The graph of y = sin x y = sin x is symmetric about the origin, because it is an odd function. The graph of y
