What slows down neutrons?
3) A defense football player on one team tackles the other team’s quarterback, who is running down the field. The quarterback is pushed to the ground by the defensive player. 4) apply Newton’s first law to explain what happened?
The force generated by the defensive player has more magnitude and as such would push the quarterback to the ground.
A force can be defined as a push or pull of an object (body), which typically results in a change of motion due to the interaction of the object (body) with another.
Newton's First Law of Motion is also referred to as Law of Inertia and it states that an object (body) in motion would continue in its state of motion at a continuous velocity (in the same speed and direction) or if at rest, it will remain at rest unless it is acted upon by an external force.
In this context, an unbalanced force is generated by the quarterback and the defensive player, but the defensive player's force is an external force with more magnitude and as such would push the quarterback to the ground.
According to Newton's First Law of Motion, the quarterback was pushed to the ground due to an external force, generated by the defensive player.

terrestrial biomes of the world what is the answer ?
Terrestrial biomes are regions categorized by climatic conditions that define the ecosystems within them. Key factors are temperature and precipitation, which influence the biodiversity, especially the suitability for certain plants and animals. Examples of biomes include grasslands, forests, deserts, and tundra.
Explanation:The terrestrial biomes of the world include diverse regions with distinct climates and ecosystems. Terrestrial biomes are categorized mainly by climate, which shapes the biodiversity within them. Factors such as temperature and precipitation are crucial in determining the types of plants and animals that can survive in each biome. For instance, in the tundra, the lack of warmth and stable temperatures prevent cold-blooded animals such as amphibians and reptiles from thriving due to their inability to maintain a constant body temperature.
Grasslands include ecosystems like the savanna and temperate grasslands, defined by their dominant ground cover of grass.Forests, such as tropical, temperate, and boreal forests, are primarily composed of trees and other woody vegetation.Deserts are arid regions with minimal precipitation, covering a significant portion of Earth's surface.Tundra is characterized by extremely low temperatures, a lack of nutrients, and a short growing season.The same type of biome can occur in different geographic locations, provided the climate is similar. Therefore, the worldwide distribution of biomes can be understood by examining patterns of climate across the globe.

four main parts of a spiral galaxy
The four main parts of a spiral galaxy are the disk, bulge, halo, and the signature arms.
What do you mean by the spiral galaxy ?In a spiral galaxy, the rotating disc is surrounded by spiral 'arms' that extend outward from a compact center region. A spiral galaxy is the Milky Way. Galaxies can be divided into four categories: spiral, barred spiral, elliptical, and irregular.
Most spiral galaxies are found in the Universe's low-density regions. They hardly ever appear in the center of galaxy clusters. The Milky Way, our own galaxy, is believed to be a spiral galaxy with a central bar.
The disk, bulge, halo, and distinctive arms are some of the distinguishing characteristics of spiral galaxies. Younger stars are often located in the disk, which emits a bluish tint and is composed of gas and space dust.
Thus, the disk, bulge, halo, and the signature arms are the four main parts of a spiral galaxy.

What contribution is a modification to Thomson plum pudding model
Seagrasses are flowering plants. Forty-nine species in 12 genera are known. The flowers are simple and open underwater; pollen is transported by waves and currents. However, they also reproduce vegetatively via rhizomes and form dense mats or meadows often composed of a single species. Totally immersed in seawater, the long, linear leaves have no stomata. The plants never exchange gases with the atmosphere. They absorb carbon dioxide that is dissolved in the water and use the oxygen they themselves produce during photosynthesis.
Considering the characteristics of seagrass, you will most likely find seagrasses in which ocean zone(s)?
A) the ocean basic and the abyss
B) the continental shelf, slope, and rise
C) the continental shelf and the sunlight zone
D) the continental shelf and slope; the sunlight and twilight zones

After considering the characteristics of seagrass, we find that the seagrass is from the continental shelf and the sunlight zone. Hence, option C is correct.
What is Photosynthesis?In order to synthesize, or create, their own food source, plants must consume light energy, hence the name "autotroph." There is a common misconception that when a plant is placed in soil, watered, or exposed to the sun that it is being "fed," although none of these actions are actually regarded to be feeding.
Instead, plants produce glucose, a type of sugar that they require to thrive, using sunshine, water, and gases from the atmosphere. Every plant, every type of algae, and even some bacteria engage in this process, which is known as photosynthesis. Plants require carbon dioxide, water, and sunlight to carry out photosynthesis.
Hence, this concludes that option C is correct.

an object moving at a constant velocity travels 274 m in 23 s. what is its velocity?
Answer:
Velocity, v = 11.91 m/s
Explanation:
It is given that,
Distance covered by the object, d = 274 m
Time taken, t = 23 s
We need to find the velocity of the object. It is given by distance covered divided by total time taken i.e.
[tex]v=\dfrac{d}{t}[/tex]
[tex]v=\dfrac{274\ m}{23\ s}[/tex]
v = 11.91 m/s
So, the velocity of the object is 11.91 m/s. Hence, this is the required solution.

If an atom had a nucleus 1 ft in diameter, what would be the diameter of the atom, in miles? (1 mi = 5,280 ft)
If an atom had a nucleus 1 ft in diameter, the diameter of the atom would be approximately 10 miles. This is based on the fact that a typical atom is about ten thousand times larger in diameter than its nucleus.
In physics, we learn that the size of a nucleus is extremely small compared to the overall size of an atom. A lead nucleus with a mass number of 208 has a diameter of about 13 femtometers (fm), which is 10-15 meters, and this is ten thousand times smaller than the typical atom's diameter. If we scale up the nucleus to 1 ft, we keep the same ratio of 1 ft to 10 thousand ft or, in other words, 1 ft to nearly 2 miles (10,000 ft divided by 5,280 ft per mile). Hence, if the nucleus's diameter is 1 ft, the atom's diameter at the same scale would be around 10 miles.

Two electrical circuits have the same 15-volt batteries. Circuit A has 2 ohms of resistance, and circuit B has 6 ohms of resistance. Which of the following statements is correct?
(1 point)
• Circuit B has the same amount of current as circuit A.
• Circuit B has more current than circuit A, as it has less resistance.
• Circuit B has less current than circuit A, as it has more resistance.
• Circuit B has less current than circuit A, as it has less resistance.
Circuit B has less current than circuit A, as it has more resistance. This is the correct statement.
Using Ohm's law, which states that the current (I) is equal to the voltage (V) divided by the resistance (R), we can determine the current in each circuit. With both circuits having a 15-volt battery and Circuit A having a resistance of 2 ohms, using the formula I = V/R, we calculate the current in Circuit A to be 7.5 amperes. Similarly, with Circuit B having a resistance of 6 ohms, its current is 2.5 amperes. Consequently, since Circuit B has a higher resistance, it allows for less current to flow compared to Circuit A.

A property that describes how easily a substance undergoes chemical changes
Chemical reactivity is the property that describes how easily a substance undergoes chemical changes. It relates to the instability of a substance, with more reactive substances typically being less stable. Factors influencing chemical reactivity include electron configuration, the presence of unpaired electrons, and the substance's position in the Periodic table.
Explanation:The property that describes how easily a substance undergoes chemical changes is known as chemical reactivity. This reactivity indirectly relates to how unstable the substance is, with less stable substances generally being more reactive. For instance, noble gases like helium or neon are very stable and exhibit low reactivity, while alkali metals like sodium are relatively unstable and show high reactivity.
Chemical reactivity can be influenced by several factors, including the particular substance's electron configuration, the presence of unpaired electrons, and the substance's position in the periodic table. Therefore, understanding a material's chemical reactivity can greatly help predict its behavior in various situations, particularly in reactions.

Which of the following is example of direct observation
Direct observation is a crucial method in scientific studies, allowing researchers to collect firsthand information. Examples include a student observing the sky to note weather conditions and a biologist using a GPS-enabled collar to track a grizzly bear's movements. These instances exemplify the use of senses or instruments to acquire data directly from the source.
Explanation:The request for an example of direct observation highlights the importance of firsthand experience in data collection in scientific studies. Direct observation involves actively acquiring information through our senses or instruments without any intermediary. One classic example of direct observation is when a student, during a field trip, looks up at the sky to record the weather conditions. This is a simple yet profound activity where the observer uses their sense of sight to gather data about the sky's color, cloud formations, and possibly even the position of the sun or moon. Additionally, a biologist tracking the movement of a grizzly bear using a GPS-enabled collar operates through direct observation, as they collect data generated from the exact source of the phenomenon being observed.
In both instances, the observers use their senses or scientific instruments to gather information about their surroundings or the subject of their study. Whether it is the student noting down the sky's appearance in a journal or the biologist examining GPS data to understand a bear's migration patterns, both scenarios exemplify direct observation. These examples underline the significance of direct observation in acquiring accurate, firsthand information that lays the groundwork for further scientific inquiry and analysis.

Use examples to explain how the atmosphere interacts with two other of Earth's spheres. Explain the interaction for each using complete sentences.
Answer:
Plants in the biosphere consume carbon dioxide from the atmosphere and emit oxygen back into the atmosphere as a result of photosynthesis. Animals consume oxygen from the atmosphere and emit carbon dioxide back into the atmosphere as a result of cellular respiration.
Explanation:
edg2020
It should be noted that the Earth has four major subsystems which are the lithosphere (land), hydrosphere (water), atmosphere (air), and biosphere.
The spheres of the Earth influence each other and they interact. For example, rain falls from the cloud in the atmosphere and then falls on the land. This shows that there's an interaction between the hydrosphere, lithosphere, and atmosphere.
Also, plants that are in the biosphere consume carbon dioxide that comes from the atmosphere. The plants then give back oxygen which is used for respiration by the animals and humans.
