ASTR 102 Quiz Questions | 100% Correct Answers | Verified | Latest 2024 Version We have learned that the centre of the milky way contains a very massive black hole. We developed this understanding by: - Monitoring the orbital motions of many individual stars in the very central parts of the Milky Way If the sun were to be squashed down small enough to become a black hole, then: - The planets in the solar system would orbit the Sun in unchanged fashion (but would receive no light from it) ...

1.6. In Wikipedia, look up "Gas giant" and answer this question: What is a gas giant? - a. A planet composed mainly of hydrogen and helium gas. 1.9. In Wikipedia, look up "Solar System", scroll down to "Kuiper belt", and answer this question: Which of the following is not a true statement about the Kuiper belt? - c. The total mass of the Kuiper belt is thought to be greater than that of Earth. In Wikipedia, look up "Angular momentum", scroll down to "Conservation of angular momentu...

We have learned that the centre of the milky way contains a very massive black hole. We developed this understanding by: - Monitoring the orbital motions of many individual stars in the very central parts of the Milky Way If the sun were to be squashed down small enough to become a black hole, then: - The planets in the solar system would orbit the Sun in unchanged fashion (but would receive no light from it) The first stellar mass black hole identified, Cygnus X-1, was found in 1973. The n...

Cygnus x-1 - correct answer A powerful x-ray source that is believed to be a black hole in our galaxy Virgo Cluster - correct answer Nearest large cluster of galaxies to our local group SBb - correct answer assignment given to a galaxy with moderately sized nuclear bulge & moderately wound arms starting from a bar through the central part of the galaxy That of an average city, about 10km - correct answer the diameter of a typical neutron star of 1 solar mass is predicted to be approxima...

Module 6 Questions and Answers Wilfrid Laurier University ASTR 102 What does the ISM (interstellar medium) mainly consist of? Dust and low-density gas No stars have been found with masses greater than 150 times our Sun because they would generate so much power that they would blow themselves apart. Which of the following main sequence stars of different surface temperature would you expect to have the greatest mass? 33,000 K Which of the following statements about main sequence stars is ...

Measuring the Speed of Light with a Microwave Oven Maria Isabel Suarez IB Biology 2 Period 3 Science Fair Project Problem Statement Does measuring the speed of electromagnetic waves in th e microwave portion of the spectrum by measuring the spacing between hot spots in a microwave oven will help me prove and understand the speed of light? Background Information Microwaves, like light, are an example of electromagnetic waves. Electromagnetic waves can travel through the vacuum of interstellar spa...

Many celestial bodies can be seen in the night sky without the use of professional equipment such as telescopes. Stars, planets, and even the Moon could be seen with the naked eye, piquing the interest of observers. Stars are visually appealing, glistening under the gaze of the dark universe, as well as giving direction to those who are lost in paths. Those silvery dots are actually light-years away from the Solar System, and when viewed through large telescopes, their color is not silver simila...

Altimeter - Answer- an instrument that uses air pressure to record height Anemometer - Answer- an instrument to measure wind speed Angiosperm - Answer- a group of plans that produce seeds enclosed within an ovary, which may mature into a fruit Annuals - Answer- plants that die after one growing season Asexual Reproduction - Answer- reproduction involving only one parent Atmosphere - Answer- Earth's is primarily nitrogen and oxygen; the troposphere extends from the surface to abou...
