An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (1)
Planet A is identified as Jupiter due to its distance of approximately 778,600,000 km from the Sun.
Planet B is identified as Neptune due to its distance of approximately 4,495,100,000 km from the Sun.
Planet C is identified as Saturn due to its distance of approximately 1,433,500,000 km from the Sun.
Planet D is identified as Uranus due to its distance of approximately 2,872,500,000 km from the Sun.
The identities of the planets are: A: Jupiter B: Neptune C: Saturn D: Uranus
Explanation
Understanding the Problem We are given a table of planets labeled A, B, C, and D, along with their distances from the Sun in kilometers. Our task is to identify each planet based on its distance from the Sun.
Strategy To identify the planets, we need to compare their distances from the Sun to the known distances of planets in our solar system.
Identifying Planet A Planet A is 778,600,000 km from the Sun. This is very close to the distance of Jupiter (778,570,000 km). Therefore, Planet A is Jupiter.
Identifying Planet B Planet B is 4,495,100,000 km from the Sun. This is very close to the distance of Neptune (4,495,060,000 km). Therefore, Planet B is Neptune.
Identifying Planet C Planet C is 1,433,500,000 km from the Sun. This is exactly the distance of Saturn (1,433,500,000 km). Therefore, Planet C is Saturn.
Identifying Planet D Planet D is 2,872,500,000 km from the Sun. This is very close to the distance of Uranus (2,872,460,000 km). Therefore, Planet D is Uranus.
Final Answer Therefore, the identities of the planets are:
A: Jupiter
B: Neptune
C: Saturn
D: Uranus
Examples
Understanding the distances of planets from the Sun helps us appreciate the scale of our solar system. This knowledge is crucial in space exploration, as it determines the time and resources needed for interplanetary travel. For example, knowing the distance to Mars is essential for planning missions to the red planet. Moreover, understanding planetary distances aids in studying the conditions on each planet, such as temperature and atmospheric composition, which are influenced by their distance from the Sun.
