Astronomy unit 10 practice test

  • How much more light would 30-meter telescope gather compared to 10-meter telescope?

    The wavelength is directly proportional to the resolution of the telescope, not to the length of the telescope.
    Since the brightness is directly proportional to the square of the length of the telescope, the images from a 30-meter long telescope will be 9 times brighter than that of a 10-meter long telescope..

  • In what ways does a 30 meter telescope outperform 10 meter telescope?

    Current 10-meter telescopes can resolve details 5-times smaller than Hubble can resolve and be 36-times brighter.
    A 30-meter class telescope will be able to see details 10-times smaller than Hubble resolution and be over 200-times brighter..

  • In what ways does a 30-meter telescope outperform 10-meter telescope?

    A 30-meter class telescope will be able to see details 10-times smaller than Hubble resolution and be over 200-times brighter..

  • Is any mathematical model that combines space and time into a single continuum?

    In physics, spacetime is any mathematical model that combines space and time into a single continuum.
    It is a mathematical concept used to refer to all points of space and time and their relation to each other.
    Historically, space and time were thought of as separate entities..

  • What determines the quality of an eyepiece?

    Focal Length and Magnification
    Perhaps the most important specification of an eyepiece is its focal length.
    The focal length of an eyepiece, along with the focal length of the telescope the eyepiece is used with, determines the magnification the combination provides..

  • What is a well tested concept that explains a large number of proven hypotheses?

    A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment..

  • What is the difference between the Milky Way and the Milky Way galaxy quizlet?

    What is the difference between the Milky Way and the Milky Way Galaxy? The Milky Way is a fairly narrow band of faint diffuse light around the celestial sphere.
    The Milky Way Galaxy is a spiral galaxy of about 100 billion stars..

  • What star is hotter than most other stars will probably look like?

    Blue stars are hotter than yellow stars, which are hotter than red stars.
    A hot star like Sirius, with a surface temperature of about 9,400 K emits more blue light than red light, so it looks brighter through a blue filter than through a red filter..

  • When physical laws as we know them began to emerge?

    In the very first second of the universe's existence, our understanding of what was going on is surprisingly good.
    We know that the concepts of time, space and the laws of physics very quickly solidified.
    From there, order started to emerge out of the chaos..

  • Which of these stars has the longest lifetime?

    A red dwarf, which is half as massive as the sun, can last 80 to 100 billion years, which is far longer than the universe's age of 13.8 billion years.
    This long lifetime is one reason red dwarfs are considered to be good sources for planets hosting life, because they are stable for such a long time..

  • Why would the English system of units be more useful if a foot container 10 inches?

    Why would the English system of units be more useful if a foot contained 10 inches? If a foot contained 10 inches, it would be an easier system of units because it would be base-10 like the metric system rather than base-12..

    Historically, space and time were thought of as separate entities.
  • Nuclei are bound together by the residual strong force (nuclear force).
    The residual strong force is a minor residuum of the strong interaction which binds quarks together to form protons and neutrons.
