Question
Chapter 7, Problem 1QP
To determine
Arrange the following events in order of the formation of a planetary system.
Expert Solution & Answer
Answer to Problem 1QP
The following events are arranged in order of the formation of a planetary system.
Explanation of Solution
A planetary system is a system of planets, their moons and other smaller objects in orbit around a star.
Primary atmosphere is composed most of hydrogen and helium.
The same time of forms that host the planet.
Secondary atmosphere is forms as a result of comet impacts, volcanism or another process. Sometimes after this formation its host planet has formed.
Conclusion:
Arrangement in order of formation of a planetary system,
- 1. Gravity collapses a cloud of interstellar gas
- 2. A rotating disk forms
- 3. Dust grains stick together by static electricity
- 4. Small bodies collide to form larger bodies
- 5. Primary atmospheres form
- 6. A stellar wind ‘turns on’ and sweeps away gas and dust
- 7. Primary atmospheres are lost
- 8. Secondary atmospheres form
Therefore, the following events are arranged in order of the formation of a planetary system.

It's a required element in women's singles figure-skating competition and is related to the arabesque performed in ballet. Figure 5.40 shows Canadian skater Kaetlyn Osmond executing a spiral during her medal-winning perfor- mance at the 2018 Winter Olympics in Gangneung, South Korea. 77.

Your computer geek friend has written a program that reads the accel- erometer and calculates the laptop's apparent weight. You're amusing yourself with this program on a long plane flight. Your laptop weighs just 5 pounds, and for a long time that's what the program reports. But then the "Fasten Seatbelt" light comes on as the plane encounters turbu- lence. Figure 4.27 shows the readings for the laptop's apparent weight over a 12-second interval that includes the start of the turbulence. 76. At the first sign of turbulence, the plane's acceleration a. is upward. b. is downward. c. is impossible to tell from the graph. 77.
