*EXTRA PTS* How much weight is needed for a 10 m high ball to achieve 400 J of potential energy?
Answer:
,Mass of the Body = 10 kg.
Height = 10 m.
Acceleration due to gravity = 9.8 m/s².
Using the Formula,Potential Energy = mgh
= 10 × 9.8 × 10 = 980 J.
(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.
∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.
∴ Kinetic Energy = 980 J.
(c). Kinetic Energy = 980 J.
Mass of the ball = 10 kg.
∵ K.E. = 1/2 × mv²
∴ 980 = 1/2 × 10 × v²
∴ v² = 980/5
⇒ v² = 196
∴ v = 14 m/s.
3. Yes - At maximum stretch the ball stops. The ball is now 2 meters plus x below the starting point where x is the stretch distance down. The total energy is all potential in the springs and gravitational and is m g (2 + x)

the carbon cycle review of terms
Answer:
A solid line would represent point on the graph that actually are included in the solution, while points that lie on dash lines aren't included in the solution.
The carbon cycle takes place in the environment, where plants, herbivores, consumers, and decomposers are present and fix the carbon in the environment.
What is the carbon cycle?The carbon cycle is important for the environment because carbon is present in the animal cell, in food, etc., and the carbon cycle is present in the given diagram. Here, the plant takes in the atmospheric carbon dioxide shown in the arrow 1, and the carbon dioxide is released by the animals and plants shown in the arrow 2.
Arrow 3 explains the rabbit taking the carbon from the food source, the plant releases oxygen and arrow 4 explains the carbon released by the decomposers from the animals and plants; and arrow 5 shows the carbon converted into fossil fuels. Arrows 6 and 7 both explain the release of carbon dioxide while plants use it for food synthesis.
Hence, the carbon cycle takes place in the atmosphere, where plants, herbivores, consumers, and decomposers are present and fix the carbon in the environment.

What characteristic do sea stars and brittle stars have in common?
Both have flexible joints.
Both have teeth-like feeding structures.
Both use tube feet to catch prey.
Both have tentacles.
Answer:
They typically have a tough, spiny surface, which inspired their name (in Greek, echinos means “spiny” and derma means “skin”). They also have the unusual ability to regrow lost body parts, and sea stars and brittle stars can regrow arms if broken off or eaten
Explanation:
Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.
What are sea stars and brittle stars?Echinoderms with a star form that belongs to the class Asteroidea are known as starfish or sea stars. These terms are frequently used incorrectly to refer to ophiuroids, which are properly called brittle stars or basket stars in common usage. Due to their membership in the class Asteroidea, starfish are also referred to as asteroids.
The benthic (bottom-feeding) fauna of the maritime environment includes brittle stars. They belong to the Phylum Echinodermata, which includes marine organisms with radial symmetry, five components, and frequent spines. They are commonly referred to as echinoderms.
Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.

Include the following words in your paragraph:
Heat
Pressure
Context and regional metamorphism
Foliated
Non foliated
Answer:
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.

Research and identify a common resource in your state and explain the consequences of rise in population on the resource.
Answer:
Pollution, crimes and overcrowding.
Explanation:
Lack of family planning is responsible for the rise of population. It brought many adverse changes in the environment such as pollution, crimes and overcrowding etc. Rise in population causes unemployment that leads to crimes in the society. It also produces pollution due to more human activities such as emission of fossil fuels and more industries should be built to provide basic needs to more population. Rise in population causes agricultural to be converted into residential area that leads to decrease food production.

Please help!!!! Grizzly bears and polar bears are very closely related, so much so that they can reproduce to form hybrid offspring. Use your understanding of natural selection to describe how polar bears became a separate classification from the grizzly.
Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear
Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.
Polar bears become separate classification from the grizzly by the natural selection known as divergent and adaptive evolutionary change.
Polar bears and grizzly bears are considered as closed to one another so they can interbreed. They both diverged from one another due to the harsh climate of the Arctic and the ecology of the region.
The changes that took place are camouflaging and pigment-free fur-coat that helped them in order to adapt to the different climates.The genetic mutation leads to such Adaptive changes when the polar bears migrated northwards.The populations living in different climates undergo natural selection that is divergent natural selection and the adaptive evolutionary changes that result in different species.Learn more about speciation:

Answer:
A. Mid-ocean ridge. I'm not sure if I'm right.
The place where the new volcanoes are less likely to be seen is mid-ocean ridge. The correct option is A.
What is volcano?A volcano is a crack in the crust of a planet, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber beneath the surface.
Volcanoes are most commonly found where tectonic plates are diverging or converging on Earth, and the majority are found underwater.
Although Australia is the only continent with no active volcanoes, it does have one of the world's largest extinct volcanoes, the Tweed Volcano.
Volcanism is directly related to plate tectonics theory. Volcanoes are only found at specific types of plate boundaries, and only rarely in the middle of ocean plates.
Thus, the correct option is A.

Suppose that the same island experiences environmental
conditions that prevent the growth of large seeds. What do you think would happen to
the average size of finch beaks? Explain your reasoning.
Answer:
The size of finch's beak depends on the size of seeds.
Explanation:
The average size of finch beaks also changes because the size of finch beak changes according to the size of seed available. If the environment contains large sized seeds so the population of finch having small beak size increases due to food availability while on the other hand, if the region contains large sized seeds so the population of finch having big beak size increases so according to the size of seeds, the size of finch's beak also changes.
