A lifecycle of star can be determined by the mass of the star.
Explanation:
Stars are formed by the clouds of gases as well as the dust which is known as nebulae. Stars also come across a cycle that is a star is formed from gases and dust , then its grow more , various changes take place while growing after that the life span ends. Millions of year take for the formation of a star, while its growing process it shines brightly for several years. When the fuel present in the stars are exhausted , the star collapse as a result explosion of the outer layer takes place which is referred to as a supernova.
1. According to Newton's first law, what happens to an object at rest if the net
force acting on the object is ON?
A. It remains at rest,
B. It begins moving at a constant speed,
C. It begins accelerating at a constant rate,
Answer:
According to Newton's first law, if the net force acting on the object that is at rest is 0N, it remains at rest.
Option: (A)
Explanation:
Out of the three laws of motion given by Sir Isaac Newton, the first law clearly states that if an object is at rest, it continues to be at rest unless and until it is acted upon by an imbalanced external force. In the given example, it is stated that the force acting on the object is 0N. Hence, it can be concluded that the object would continue to be at rest.If the Universe was born at the Big Bang, what existed before then?
b) Nothing, as time and space themselves began with the Big Bang.
This is the most widely accepted cosmological explanation of how the universe came into existence. The theory proposes that the universe began about 13.77 billion years ago from an extremely hot and dense state.
In Big Bang models, the universe started from a singularity, which is a point where density and temperature are thought to become infinite. This point marks the beginning of both space and time. Since a singularity can't be included as an event in spacetime, this implies that time itself started at the moment of the Big Bang.
Since time and space themselves originated from the Big Bang, the concept of 'before' loses its meaning. Our current models and understandings of physics indicate that there was no 'before' in any conventional sense because time did not exist.
Complete question-
If the Universe was born at the Big Bang, what is the prevailing theory about what existed before it?
a) A pre-existing universe that contracted into a singularity
b) Nothing, as time and space themselves began with the Big Bang
c) A vast ocean of matter and energy
d) A parallel universe that merged with our own

Imperialism of European states led to the dissatisfaction of some, especially Germany, and that is why they started creating political and military alliances.
Explanation:
The first group consisted of England, France and Russia with their allies (the Entente), seeking to protect their "legal rights" acquired in colonial conquests, while the second group was represented by belligerent Germany and its ally Austria-Hungary (Central Powers), who were dissatisfied with their status. So they sought to gain as much as possible from the already conquered colonial territories.

A circular Flower bed is 20 m in diameter and has a circular sidewalk around it that is 3 m wide. Find the area of the sidewalk and square meters.
Answer: [tex]216.76 m^{2}[/tex]
Explanation:
Assuming the shape of the circular flower bed with its sidewalk is as shown in the figure, where the flower bed is the inner white circle and the sidewalk is the black part; we have to circles, hence two areas:
[tex]A_{1}=\pi R^{2}[/tex] (1)
And:
[tex]A_{2}=\pi r^{2}[/tex] (2)
Where:
[tex]A_{1}[/tex] is the area of the outer circle
[tex]A_{2}[/tex] is the area of the inner circle
[tex]r=\frac{diameter}{2}=\frac{20 m}{2}=10 m[/tex] is the radius of the inner white circle
[tex]R=10 m+ 3 m=13 m[/tex] is the radius of the outer black circle
So, the area of the sidewalk will be:
[tex]A=A_{1}-A_{2}[/tex] (3)
Substituting (1) and (2) in (3):
[tex]A=\pi R^{2}-\pi r^{2}[/tex] (4)
[tex]A=\pi (R^{2}-r^{2})[/tex] (5)
Solving with the given data:
[tex]A=\pi ((13 m)^{2}-(10 m)^{2})[/tex] (6)
[tex]A=\pi ((13 m)^{2}-(10 m)^{2})[/tex] (7)
Finally:
[tex]A=216.76 m^{2}[/tex] This is the area of the sidewalk
Which are ways in which heat energy leaves the surface of land masses? Select the three correct answers.(2 points)
evaporation
glacial motion
animal activity
conduction to air, which then rises in convection
plant growth
radiation of infrared energy
Evaporation
Conduction to air, which then rises in convection
Radiation of infrared energy
Explanation:
Evaporation is a method where the water changes from the liquid stage to the gas stage. The liquid molecules will collide with each other when they are changing their phase. During this change, there will be a little energy transformation happening from one molecule to another. Conduction is the process at which the electricity or the heat transmitted through the medium when the difference in temperature occurs. In this process, the material is not moving. Convection movement will happen in gases and liquids because of their tendency to get hotter. Less dense molecules will go up and the denser molecule will come down which eventually transfer heat. Radiation is the energy emission in form of subatomic particles, electromagnetic waves and other high energy particles.The correct statement regarding the ways in which the heat energy so produced leaves the surface of land masses are by the ways of evaporation, conduction to air later rising in convection and radiation of infrared energy.
So, the correct options that match with the statements quoted above are A, D and G. These are the ways in which heat energy can be converted.
Heat Energy. Heat energy can only be transferred from one form to another, and it can never be created or destroyed. Evaporation refers to conversion of water or liquid bodies to the gaseous state.Conduction to air can be referred with an example that Sodium metal starts catching fire, which is a form of heat at normal room temperature. Radiation in the form of infrared energy refers to the transfer of heat energy due to waves that are passed through an object.Hence, the correct options are A, D and G that the heat energy leaves the surface of land masses by the ways of evaporation, infrared radiation and conduction to air.

Middle America is an isthmus that connects North and South America.
Explanation:
Middle America, or more commonly referred to as Central America, is actually part of North America. It represents the southernmost part of the continent, but is often put as a separate region because of its shape which makes it distinct from the rest of the continent. In fact, it can be said that Middle America is an isthmus that is connecting the two large continental masses of North America and South America.
This region's northern boundary is still disputable, and it varies from author to author, though in general it is borders of Belize and Guatemala that are taken as the northernmost parts. On the south it is Colombia's border, on the east it is the Caribbean Sea, while on the west is the Pacific Ocean.

Answer:
E.)Fish ladders are quite successful in letting fish swim upstream to spawn.
Explanation:
The option stating that 'Fish ladders are quite successful in letting fish swim upstream to spawn' is not a direct impact caused by dams but a solution to mitigate an impact, specifically the blockage of fish migration paths.
The question "Which of the following is NOT an impact caused by dams?" touches on important environmental effects related to dam construction. Among the options given, C. Fish ladders are quite successful in letting fish swim upstream to spawn is NOT a direct impact of dams but rather a mitigation effort to alleviate one of the impacts. Dams have significant environmental consequences, including altering river habitats, blocking fish migration, changing water temperature and chemistry, and reducing downstream water flow, which can lead to loss of wetlands and downstream waterfalls, amongst other effects. However, fish ladders are engineered structures designed to help migratory fish bypass dams, and while they represent an effort to address one of the negative impacts of dams on ecosystems, their existence and success rate do not negate the overall adverse effects caused by dam construction.

How are landforms near the edge of continents different from landforms in the continental interior? How are these landforms related to plate tectonics or processes in the rock cycle?
The landforms in the interior of the continents and at their margins mostly differ because of the difference in geological activity.
Explanation:
The landforms that are found in the interior of the continents tend to be old. They also are mostly consisted of sedimentary and metamorphic rocks. In general the erosion is much more evident and dominant, thus the landforms also are with lower elevations when compared with the ones on the edges. This is due to the lack of geological activity as the interiors of the continents tend to be far away from the plate boundaries.
The landforms on the edges of the continents tend to be younger in general. The reason for that are the subduction zones and intense geological activity. The intense geological activity is due to the close proximity of the plate boundaries. The landforms tend to be higher in general, and volcanic arcs are also a common sight.

Landforms near the edge of continents differ from those in the continental interior. Plate tectonics plays a significant role in the formation of these landforms, such as mountain ranges and rugged coastlines. The rock cycle also influences the development of these landforms by transforming rocks into different types that contribute to their formation.
Explanation:Landforms near the edge of continents are different from landforms in the continental interior in several ways. Near the edge of continents, you will typically find mountain ranges and rugged coastlines, such as the Rocky Mountains in North America or the Andes in South America. These landforms are formed by plate tectonics, where continental masses collide and create intense pressure, causing the Earth's crust to buckle and fold. In contrast, the continental interior may have more flat or gently rolling landscapes, such as plains or plateaus, which are not directly formed by plate tectonics but may be influenced by other geological processes like erosion and deposition.
Plate tectonics is the driving force behind the formation of many landforms near the edge of continents. When two continental plates collide, they push against each other, causing the Earth's crust to fold and uplift, leading to the formation of mountain ranges. For example, the Himalayas in Asia were formed by the collision between the Indian Plate and the Eurasian Plate. These mountain ranges can also be associated with volcanic activity, as the intense pressure and heat generated by plate collisions can result in the formation of volcanoes.
Processes in the rock cycle also play a role in shaping landforms near the edge of continents. The rock cycle involves the continuous transformation of rocks from one type to another, including the formation of sedimentary, igneous, and metamorphic rocks. As tectonic forces act on the Earth's crust, rocks are subjected to intense pressure and heat, which can result in their transformation into different types of rocks. These rock types can contribute to the formation of various landforms, such as the layered sedimentary rocks found in canyons or the hardened lava flows of volcanic mountains.
