An electromagnet is different from a permanent magnet because a electromagnet _____.
A: is magnetic
B: can push and pull
C: can attract some metals
D: can turn on and off
A permanent magnet is permanent while an electromagnetic acts as a magnet when electric current passes through.
It’s a temporary magnet but yes, it can be magnetic
It can be reversed due to which way the current is moving
This means when there isn’t a current it can turn off causing it to turn on and off depending on the current
The answer is D
Hope this helps! :3
Considering the definition of electromagnet and permanent magnet, the correct answer is option D: An electromagnet is different from a permanent magnet because a electromagnet can turn on and off.
An electromagnet is magnetized by the magnetic field generated by an electric current in a coil of wire. The more current flows through the coil, that is, the stronger the magnetic force of the electromagnet.
A permanent magnet is an object capable of maintaining the state of magnetization for a long period of time. Unlike an electromagnet, a permanent magnet can remain in an active state without external support.
So, an electromagnet is nothing more than a magnet whose magnetic field is produced by the passage of electric current. Its behavior is very similar to that of a permanent magnet, with the difference that its intensity can be controlled, increased and decreased, changing the intensity of the electric current that circulates. When the current is finished circulating, when it is disconnected, the magnetism disappears.
For its part, the permanent magnet does not depend on electric current for its operation and to provide its magnetism. The permanent magnet is, as the name implies, permanent, so it is permanently magnetic.
In summary, the correct answer is option D: An electromagnet is different from a permanent magnet because a electromagnet can turn on and off.

which of the following is NOT one of myers’s 10 suggestions for a Happy Life ?
Answer:
this is the suggestions for a happy life by Myer's because you didn't give anything.
Explanation:
Want a Happier Life?
Realize that enduring happiness doesn't come from success. People adapt to changing circumstances—even to wealth or a disability. Thus, wealth is like health: its utter absence breeds misery, but having it (or any circumstance we long for) doesn't guarantee happiness.
Take control of your time. Happy people feel in control of their lives. To master your use of time, set goals and break them into daily aims. Although we often overestimate how much we will accomplish in any given day (leaving us frustrated), we generally underestimate how much we can accomplish in a year, given just a little progress every day.
Act happy. We can sometimes act ourselves into a happier frame of mind. Manipulated into a smiling expression, people feel better; when they scowl, the whole world seems to scowl back. So put on a happy face. Talk as if you feel positive self-esteem, are optimistic, and are outgoing. Going through the motions can trigger the emotions.
Seek work and leisure that engages your skills. Happy people often are in a zone called "flow"—absorbed in tasks that challenge but don't overwhelm them. The most expensive forms of leisure (sitting on a yacht) often provide less flow experience than gardening, socializing, or craft work.
Join the "movement" movement. An avalanche of research reveals that aerobic exercise can relieve mild depression and anxiety as it promotes health and energy. Sound minds reside in sound bodies. Off your duffs, couch potatoes.
Give your body the sleep it wants. Happy people live active vigorous lives yet reserve time for renewing sleep and solitude. Many people suffer from a sleep debt, with resulting fatigue, diminished alertness, and gloomy moods.
Give priority to close relationships. Intimate friendships with those who care deeply about you can help you weather difficult times. Confiding is good for soul and body. Resolve to nurture your closest relationship by not taking your loved ones for granted, by displaying to them the sort of kindness you display to others, by affirming them, by playing together and sharing together. To rejuvenate your affections, resolve in such ways to act lovingly.
Focus beyond the self. Reach out to those in need. Happiness increases helpfulness (those who feel good do good). But doing good also makes one feel good.
Keep a gratitude journal. Those who pause each day to reflect on some positive aspect of their lives (their health, friends, family, freedom, education, senses, natural surroundings, and so on) experience heightened well-being.
Nurture your spiritual self. For many people, faith provides a support community, a reason to focus beyond self, and a sense of purpose and hope. Study after study finds that actively religious people are happier and that they cope better with crises.
Intro to Psychology final.
4. d. Focus on other people.
It is easy to confuse this because Myers' has something similar on the list but d is the right answer.

_______ is the process where plastic-eating fungi are sent to landfills
Answer:
Bioremediation
Biological augmentation
Biodiversity expansion
Pollution cleanup
Explanation:
Biological augmentation is the method where plastics eating fungus are sent to landfills.
The process of sending plastic-eating fungi to landfills represents a solution to manage plastic waste, a significant environmental challenge. Fungi, especially saprobes, are known for their ability to decompose organic matter and certain synthetic materials. This bioremediation technique, if successful, could help in reducing persistent plastic waste.
Explanation:The process where plastic-eating fungi are sent to landfills represents an ecological strategy to address our growing plastic waste problem. Fungi, most of which are saprobes, play a crucial role in the decomposition process, breaking down organic matter and in some cases, synthetic materials like plastic.
Plastic waste, much of which is single-use, is a significant environmental issue due to its persistence in our ecosystems, particularly in landfills where a single plastic bottle can take up to 450 years to decompose. With a staggering daily disposal rate of 50 million bottles in the U.S. alone, the plastic problem is intensifying.
Fungi primarily derive their nutrients from decaying organic matter, often breaking down compounds such as cellulose and lignin into absorbable glucose molecules. This ability has led to this decomposer's potential use in bioremediation, where organisms are used to help reduce pollution and waste. Considering their propensity for decomposition, certain fungi species that can eat plastic are being developed and investigated, which if successful, could provide a sustainable way to reduce the problematic buildup of plastic in our landfills.

If only 10% of the energy from one trophic level passes up to the next level, what happens to the 90% energy that is not passed on?
Answer:
It is lost as heat.
Explanation:
As energy is transferred from one trophic level to the next, energy involved in metabolic processing(breaking of chemical bonds) is converted into heat energy.
Energy from metabolic activity, or the breakdown of chemical bonds, is transformed into heat energy when it is passed from one trophic level to the next.
What is the ten percent law?
A linear relationship is created when an organism depends on another for its nutritional needs and that other organism depends on another. Raymond Lindemann presented the 10% law of energy transmission in a food chain.
According to the 10% law of energy transfer, this occurs whenever energy is moved from one trophic level to another. There is a significant reduction in energy until it reaches the topmost trophic level since only 10% of energy transfers to the next trophic level and 10% of that energy level goes to the next energy.
The food chain has a total of four trophic levels. Grass makes for the first trophic level and is present at the producer level. It gets solar energy, utilizes the majority of it to prepare food, and only uses a little percentage of it. Rabbits are at the fourth trophic level and constitute the seemed trophic level, receiving 10% of their energy from them.
Therefore, the rest of the energy is lost in the form of heat.

Scientists use meteorites that hit Earth to provide evidence of the composition of Earth’s interior because they hypothesize that _____.
meteorites are made of the same material as peridotite and lava
meteorites have the same P and S wave speeds as rock samples
meteorites are made of the original material from which Earth formed
meteorites contain a smaller percentage of iron than Earth’s crust
Answer:
meteorites are made of the original material from which Earth formed
Explanation:
Meteorite is a fragment that passes through the earth's atmosphere and strikes the earth.
It is a metallic or stony body which is able to enter the earth.
Meteorites are widely believed to have formed with the earth when the solar system and other planets formed. They contain records of the earth's original composition. This is the main reason why they are suitable for radioactive dating. Example is the Stony Antarctica meteorites. Some of these meteorites have preserved their original composition.
Meteorites can be classified as stony, iron and stony-iron.
Some special set of meteorites contains lumps of materials that are thought to have formed first. These lumps are called chondrules. Meteorites with chondrules are called chondrites. These chondrules are rich in radioactive minerals and are very suitable for dating the earth.
Some meteorites also contain some black carbon matter that has been analysed to be amino acid. This has been very useful in understanding how life formed on earth. It provides an exotic origin of life on earth. These types of meteorites are called carbonaceous meteorites.
A good meteorite for dating would be one that is still very intact and has not weathered. Weathering affects the effectiveness of using earth materials for dating.
Meteorites provide evidence of Earth's interior composition because they are made of materials from which Earth originally formed, offering insights into the solar system's history and Earth's early building blocks.
Explanation:Scientists use meteorites that hit Earth to provide evidence of the composition of Earth’s interior because they hypothesize that meteorites are made of the original material from which Earth formed. Meteorites offer a glimpse into the early history of the solar system and are composed of primitive materials that have not been altered by heat or pressure since their formation. These celestial objects are believed to be remnants from the solar system's formation process, providing crucial information about the materials that constituted early Earth before it underwent differentiation and chemical processing. The study of meteorites helps scientists to understand the building blocks of Earth by offering a comparison with Earth’s interior composition, particularly the mantle and core.
what happens to ideas in science?
New ideas are discovered as a result of accumulated knowledge and a being's interest or necessity.
What is science?Science is the endeavor and development of scientific and interaction with the natural and social worlds through a systematic and evidence-based methodology.
Many consider Aristotle to be the first scientist, despite the fact that the term predates him by even more than two millennia.
He spearheaded the techniques of reasoning, observation, inquiry, and demonstration in Greece in the fourth century BC.
Since they are based on evidence, scientific theories are far more reliable and likely to be true than other types of ideas. Developing new scientific ideas is all about gathering evidence.

Ideas in science are continually tested and revised, and new observations can lead to the refinement or replacement of existing theories, known as paradigm shifts. Scientific ideas evolve over time based on evidence, and established theories can be challenged by compelling new data, contributing to a greater understanding of the natural world.
What happens to ideas in science? In essence, science is a dynamic and evolving field, where ideas are continually being tested, revised, and replaced. These changes to scientific understanding happen due to new observations, experiments, and technologies that challenge current theories. For example, Mendel's laws of inheritance were not dismissed with new genetic discoveries; instead, they were incorporated into a broader understanding of heredity. This process of refinement and sometimes radical change, also known as paradigm shifts, is fundamental in science and was described by Thomas Kuhn. Over time, through an accumulation of evidence and scientific rigor, ideas are strengthened or discarded, contributing to an ever-more detailed and accurate understanding of the natural world.
While established theories, like those of evolution, cell theory, and the physicochemical theory of life, are widely accepted due to robust supporting evidence, scientists maintain an openness to alternative explanations and remain vigilant for new data that might suggest revisions. Scientific ideas are not static; they are continually tested against the observable universe, refined, and improved to enhance their explanatory and predictive power.

Explanation:
Prominences are indeed a common phenomenon observed in the Sun's atmosphere, specifically in the solar chromosphere and corona.
A prominence is a relatively cooler and denser structure composed of solar gases, primarily hydrogen and helium, that becomes visible as a bright, arch-like or loop-like feature extending from the Sun's surface. Location: Prominences are located above the Sun's visible surface, known as the photosphere, in the outer layers of the solar atmosphere. They are best observed during solar eclipses or through specialized solar telescopes equipped with filters to block out the intense brightness of the Sun's photosphere. Types of Prominences: There are two main types of solar prominences: quiescent prominences and eruptive prominences.
prominences are prominent features seen in the Sun's outer atmosphere, characterized by arch-like structures formed by cooler and denser solar gases. They are manifestations of the Sun's complex magnetic activity and provide valuable insights into solar behavior, contributing to our understanding of solar physics and space weather phenomena.

How does ATP release energy that's stored within the molecule?
Answer:
ATP releases energy stored within the molecule by the procedure known as ATP hydrolysis. In the hydrolysis of ATP, the energy gathered in the high-energy phosphoanhydride bonds in ATP gets discharged due to the dissociation of these bonds, like in muscles, where work is generated in the form of mechanical energy.
The products formed in the process are inorganic phosphate and ADP. This ADP can get further dissociated to produce AMP and another orthophosphate.
How does the circulatory system interact with the muscular system
The circulatory system provides oxygen and nutrients to the muscles and removes waste products. During exercise, the circulatory system increases blood flow to the working muscles.
Explanation:The circulatory system interacts with the muscular system by providing the necessary blood supply to deliver oxygen and nutrients to the muscles, while also removing waste products such as carbon dioxide. The heart, which is part of the circulatory system, pumps oxygenated blood to the muscles through the arteries. The blood vessels in the muscular system, known as capillaries, then facilitate the exchange of oxygen and nutrients with the muscle cells.
The interaction between the circulatory and muscular systems is crucial during exercise. When muscles contract during physical activity, they require more oxygen and nutrients. The circulatory system responds by increasing the heart rate and dilating blood vessels to deliver a higher volume of blood to the working muscles. This increased blood flow helps to maintain muscle function and prevent fatigue.
