Choose the best answer to each of the following. Explain your reasoning.
Which of the following correctly lists our “cosmic address” from smallest to largest? (a) Earth, solar system, Milky way Galaxy, Local Group, Local Group, Local Super-cluster, universe (b) Earth, solar system, Local Group, Local Super-cluster, Milky Way Galaxy, universe (c) Earth, Milky Way Galaxy, solar system, Local Group, Local Supercluster, universe.
The correct listing of our "cosmic address" from smallest to largest.
Answer to Problem 1QQ
The correct listing of our cosmic address" is (a) Earth, solar system, Milky Way galaxy, Local Group, Local Supercluster, universe.
Explanation of Solution
Introduction:
The universe is extremely vast, consisting of millions of galaxies, stars and planetary systems. The Earth and the solar system are tiny parts of the universe.
The Earth is the third planet from the Sun in our solar system. The Solar system is in the Milky Way galaxy. The Milky Way galaxy is a part of the local group of galaxies. The Local group contains nearly 54 galaxies. The local group is a part of the Virgo Cluster which is in turn a part of the Laniakea Supercluster. The Universe contains many such superclusters.
Conclusion:
Therefore, the correct listing of our cosmic address" is (a) Earth, solar system, Milky Way galaxy, Local Group, Local Supercluster, universe.

- An ideal gas in a sealed container starts out at a pressure of 8900 N/m2 and a volume of 5.7 m3. If the gas expands to a volume of 6.3 m3 while the pressure is held constant (still at 8900 N/m2), how much work is done by the gas? Give your answer as the number of Joules.arrow_forwardThe outside temperature is 25 °C. A heat engine operates in the environment (Tc = 25 °C) at 50% efficiency.
