Answer:

D. The universe

Explanation:

just got it correct

We may observe a sphere with a diameter of around 28 billion light years because the cosmos is enormous and has been expanding for about 13.8 billion years at a rate that is only a small fraction of the speed of light. Thus, option D is correct.

Even just exploring our galaxy would take countless millennia, let alone the entire universe. The Hyperion Supercluster galaxy supercluster is another old formation.

The largest and most numerous galaxy is the universe. A galaxy is a massive cluster of gas, dust, billions of stars, and their solar systems that are all bound together by gravity.

Therefore, No, every solar system and galaxy can be found in the cosmos. The Milky Way Galaxy contains hundreds of billions of stars, including our Sun, while the universe itself is made up of billions of galaxies.

Its A. inductive Reasoning. He had no idea that it was true, but he assumed

Explanation:

Initial speed of the driver, u = 15 m/s

Acceleration of the driver, [tex]a=-2\ m/s^2[/tex]

Final speed of the driver, v = 10 m/s

Let t is the time taken by the driver to accelerate to the final speed. Using first equation of kinematics as :

[tex]t=\dfrac{v-u}{a}[/tex]

[tex]t=\dfrac{10-15}{-2}[/tex]

t = 2.5 seconds

Let d is the distance the car moved during the breaking period. Using the third equation of kinematics as :

[tex]v^2-u^2=2ad[/tex]

[tex]d=\dfrac{v^2-u^2}{2a}[/tex]

[tex]d=\dfrac{(10)^2-(15)^2}{2\times (-2)}[/tex]

d = 31.25 meters

Hence, this is the required solution.

The one who might benefit financially, the most from the EPA's claim are  cookware manufactures who make pans out of steel only.

A compound or element which reacts with the other element to form a product.

Chemicals are generally toxic because they harm our skin, when they come in contact with the body. When exposed to a toxic substance, gasoline can affect your health. Since, drinking gasoline can cause burns, vomiting, diarrhea and can cause death.

Cookware companies which have been using a chemical called C-8, that helps to create a nonstick coating to pans. Since, the Environmental Protection Agency (EPA) recently claimed that the use of C-8 in the manufacturing of nonstick cookware should be stopped. The reason for this discontinuation is that studies show it causes cancer.

There are also the companies who made cookware out of steels only. They are most benefited by this claim.

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.

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.

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.

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.

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.

Answer:

Law of conservation of mass.

Difference in air pressure

Humid air has lower air pressure because humid air contains lots of water. As more and more water enters the atmosphere it displaces other, heavier molecules. As a result air that is humid is much lighter. Since humid air is lighter, it has less weight to press down with so it has lower pressure.

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.

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.

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.

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.
