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!
