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.

Thus, Steel cookware manufactures are benefited by EPA claim.

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 potential energy of the miner when he moves 15 meters vertically downward is 13,230 Joules.

To calculate the potential energy of the miner as he moves 15 meters vertically downward, you can use the formula for gravitational potential energy:

Formula is given as m x g x h

Now, calculate the potential energy:

[tex]\[PE = 90 \, \text{kg} \cdot 9.8 \, \text{m/s²} \cdot 15 \, \text{m} = 13,230 \, \text{Joules}\][/tex]

The potential energy of the miner when he moves 15 meters vertically downward is 13,230 Joules.

Answer:

Scientists develop knowledge by making observations about the natural world that may lead to a scientific question

Explanation:

Science has been able to change history and develop some elemental theories that explain how everything works by following some steps. These steps are known as the "scientific method", which can be described as a systmatic way of learning about the world and answering questions. The most basic step that allow scientists to develop questions about something is the observation, by observing things doubts will emerge. This will lead to the next step that is asking questions. In this way your research problem will be more accurate and therefore easier to study. The following steps are: form an hypotesis, make a prediction based on the hypotesis and test the prediction.

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:

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.

Final answer:

The optimal month for Jim to plant coffee beans is June, before the snow season and during the warm, moist climate period. Climatic factors and temperature changes due to climate change should also be considered in planning for coffee production.

Explanation:

The best month for Jim to plant coffee beans on his farm, considering the climate requirements for coffee growth (warm, moist, and sunny conditions) and the pattern of snow from November, would be June. This period, just after the moderate temperatures from June to October, would offer the newly planted coffee trees the optimal window for warm temperatures before the cold, snowy conditions set in. It's important for Jim to avoid the snow season and capitalize on the warm and moist period for the plantation.

Moreover, climate change has been an increasing concern for coffee production globally. In regions like Colombia, rising temperatures and changes in precipitation have adversely affected coffee output, requiring the development of new agricultural methods. Jim should be aware of and prepared to respond to these challenges by considering shade-grown coffee and soil health management to potentially mitigate climate change impacts.

triple beam balance and meterstick

The set of instruments that would be helpful to determine the density of an object are triple beams balance and meterstick

Triple beam balance refers to an instrument that can be used to measure the mass of different objects. It is called triple beam balance because it is made up of three beams.  

Each of the beams has different weights and their size matches the gradations of the notched scale present on each of the beam. The size of the beams varies, the middle beam has the largest size, the far beam has a medium size and the font beam is the smallest size.

The basic parts of a triple beam include:

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.

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.

Explanation:

Explanation:

The food chain consists of autotrophs (producers) and heterotrophs (consumers). All animals and plants fall into these categories.

The autotrophs are the first stage of the food chain. They are mostly plants. They use the radiation from the sun to fulfill their energy needs. In doing this process the autotrophs release oxygen. The process is known as photosynthesis. The plants take in carbon dioxide in the atmosphere released by heterotrophs during respiration and the plants in turn release carbon dioxide. Also, autotrophs provide a food source for the heterotrophs.

Every producer and consumer interact in some way, completing food chain.
