The star's stages in chronological order are: main sequence, red giant phase with helium fusion, red giant phase with carbon-oxygen core formation, and finally, a white dwarf cooling over time.
Stars with the same mass as the Sun follow a particular sequence of stages. Firstly, they begin life in the main sequence, fusing hydrogen to produce helium. As the hydrogen fuel is exhausted, the star expands and cools to become a red giant, and begins fusing helium to carbon and oxygen. After the central helium is depleted, the star again turns into a giant, leading to increase in luminosity and decrease in temperature. Formation of a carbon-oxygen core in this stage marks the transition towards the end of the star's life. The star loses mass, exposes its hot inner core and becomes a white dwarf, cooling slowly as it radiates away its remaining energy.

You would use
P^2 = (2π)^2(D^3)/((G)(M))
where P is the orbital period in seconds, D is the distance in meters, M is the mass in kilograms of Jupiter, and G is the 6.67 x 10^ -11 m^3/ kg sec^2
M Jupiter = 1.9 x 10^27 kg, D = 1.88 x10^9 meters
P^2 = 39.5*(6.65 x 10^27)/(( 6.67 x 10^ -11)(1.9 x 10^27)) = 2.07 x 10^12
P = 1,440,000 seconds = 16.66 days
ANTECEDENT RIVER
An antecedent river is a river that is younger than the underlying geological structure over which it flows.
In areas with active tectonic activity or where erosion significantly affects the landscape, antecedent rivers are frequently discovered. They are an intriguing geological phenomenon that can shed light on how a region's geology has changed through time. Even if the geography of the underlying rocks changes, antecedent rivers do not alter their route.

g. deposition (9)
h. weathering (1)
i. contour lines (4)
j. erosion (5)

Explanation:
Continental shelf
Continental slope
Volcanic arc
Answer:
Continental slope
Explanation:
b.is made from cooling magma
c.usually forms horizontal layers
d.does not contain fossils
Sedimentary rock are usually forms horizontal layers. Sediment refers to the constituent particles of a sedimentary rock. The correct option is (c).
Along with igneous and metamorphic rocks, sedimentary rocks are one of the three primary categories of rocks. They are created by the compaction of sediments from the ocean or other activities on or near the Earth's surface.
Erosion, weathering, dissolution, precipitation, and lithification are the main geological processes that result in the formation of sedimentary rocks.
The impacts of wind and rain, which gradually reduce huge boulders into smaller ones, are included in erosion and weathering. Boulders and even mountains become sediments, such as sand or mud, as a result of erosion and weathering.
Therefore, Sedimentary rock are usually forms horizontal layers. Sediment refers to the constituent particles of a sedimentary rock.

B. peaceful zone
C. war zone
D. Economic zone
Answer:
A. demilitarized zone
Explanation:
It is called the Demilitarized Zone (DMZ) the 5 km wide region that surrounds the border between the two Koreas (North Korea, socialist state and South Korea, capitalist-inspired government). Such an area was created after the 1953 armistice, which "interrupted" the conflict between the two Korean states. In practice, both countries are still in a state of belligerence, meaning no peace treaty to end the conflict has been signed to date.
