Week 7 Science Quiz   Question 1 10 / 10 pts One lap around the sun, which is 93 million miles away on average, takes us 365 days, 5 hours, 48 minutes and 46 seconds. Approximately how fast must the Earth travel around the sun to orbit the sun in one year?    500 miles per hour      1,000 miles per hour      5,000 miles per hour      10,000 miles per hour   Correct!    70,000 miles per hour   Good work   Question 2 10 / 10 pts In the early universe, despite looking like a chaotic sea of particles, the entropy would have been lower than it is today. Correct!    True      False   Good work   Question 3
10 / 10 pts In general, an expansion of space always leads to an increase of entropy. Correct!    True      False   Good work   Question 4 10 / 10 pts In the Early Universe, matter wanted to clump together under the gravitational force to increase entropy and break the smoothness of the curved spacetime. Correct!    True      False   Good work   Question 5 10 / 10 pts Does a sandcastle have higher or lower entropy than a pile of sand?    Higher   Correct!    Lower   Good work   Question 6 10 / 10 pts
It would take 225,000,000 years for our solar system to orbit the Milky Way Galaxy, with the center approximately 160,000,000,000,000 miles away from our sun. Roughly how fast must we be traveling in the galactic plane to accomplish this feat?    5,000 miles per hour      10,000 miles per hour      50,000 miles per hour      100,000 miles per hour   Correct!    500,000 miles per hour   Good work   Question 7 10 / 10 pts In the past, entropy was lower than it was now. In this sense, the moment of the Big Bang represents the lowest total entropy that our Universe ever had. Correct!    True      False   Good work   Question 8 10 / 10 pts That Orthodox, Jewish Physicist is proposing that when a group of atoms is driven by an energy source, it will gradually restructure itself to dissipate more energy meaning that an increase in entropy can drive complexity. In this sense, complexity is actually preferred. Correct!

   True      False   Good work   Question 9 10 / 10 pts Which scientist once said that “if your theory is found to be against the Second Law of Thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation?”    Einstein      Newton      Lemaitre   Correct!    Eddington      England   Good work   Question 10 10 / 10 pts What object was used during the Stone Age to mark phases and periods of time as one of the first attempts in chronometry?    A watch      A pulsar
