Why does the coil of wire in a speaker become attracted to or repelled by the permanent magnet on the back of the speaker?

Answers

Answer 1

The second speaker's cone and coil will vibrate, causing a change in magnetic field on the magnet, which will induce a current along the wire to the first speaker. The current induces a magnetic field on the first coil, which is then attracted and repelled from the magnet, causing the cone to vibrate and produce sound

Answer 2

The coil of wire in a speaker become attracted to or repelled by the permanent magnet on the back of the speaker due to the magnetic field induced by the current in the speaker.

What is the significance of magnetic field?

A magnetic field can be referred to or considered as an environment that attracts the magnetic elements towards itself. Moreover, the magnetic field also develops a current around the environment that it is present in.

When the permanent magnet is placed near a speaker, the coils present  in the speaker generate an electromagnetic induction, and as a result, they attract or repel each other due to the formation of an artificial magnetic field near the speaker.

Therefore, the significance regarding magnetic field has been aforementioned.

To support your answer, quote one or two sentences from the article that convey the author's central point.

Answers

Answer:

The summary of the issue is outlined in the following paragraph.

Explanation:

The recently approved ERA to the U.S constitution establishes that sometimes "the true equality of liberties under this same legislation won't be denied as well as abbreviated either by the U.S on the grounds of gender. "Whenever the U.S. Law was passed throughout 1787, the privileges it asserted have been assured equivalently to some straight white men. Hardly 7 States had adopted the executive order throughout the allocated time. That several people are too afraid of its potential unexpected consequences including its constitution even though it was vague and ambiguous.

The whole critical change will indeed ensure equal equality of the genders by making sure that public services, as well as government funds, benefit both genders equally.

8. Specialization, or division of labor (4 points)
O Results in a lower standard of living
Provides the most efficient use of limited resources
O Increases unemployment
All of the above

Answers

Answer:

Provides the most efficient use of limited resources.

Explanation:

Job specialization can be defined as a strategic process which typically involves the ability of employees working in an organization to develop specific skills, knowledge, great expertise or professionalism and experience to perform their duties, tasks or job functions effectively and efficiently.

In order to gain the requisite skills, expertise and knowledge for job specialization, it is very important for the employees to have undergone an extensive training and a good number of years in work experience.

One of the advantages of specialization is to increase efficiency and productivity because the employees are able to specialize in the use of specific tools (equipments) to accomplish their tasks, as well as limit the level of error or mistakes in the production process.

Division of labor refers to a method of production in which a project or task is divided into multiple sections and a group of workers (employees) are assigned specific tasks to complete based on their skill set, expertise, knowledge or area of specialization.

Hence, specialization, or division of labor provides the most efficient use of limited resources by eliminating wastage and maximizing value for growth and development in an organization.

Which sentence contains the central idea of this excerpt from President Bill Clinton’s letter of apology addressed to Japanese Americans who were relocated? Over fifty years ago, the United States Government unjustly interned, evacuated, or relocated you and many other Japanese Americans. Today, on behalf of your fellow Americans, I offer a sincere apology to you for the actions that unfairly denied Japanese Americans and their families fundamental liberties during World War II. In passing the Civil Liberties Act of 1988, we acknowledged the wrongs of the past and offered redress to those who endured such grave injustice. In retrospect, we understand that the nation’s actions were rooted deeply in racial prejudice, wartime hysteria, and a lack of political leadership. We must learn from the past and dedicate ourselves as a nation to renewing the spirit of equality and our love of freedom. Together, we can guarantee a future with liberty and justice for all. You and your family have my best wishes for the future.

Answers

The sentence that contains the central idea of the excerpt from President Bill Clinton’s letter of apology was: “Today, on ……….. liberties during World War II.” Hence, Option B is correct.

What is the letter of apology?

An apology letter is a formal admission that the writer's actions or words hurt someone else or a group of people. It can be used to make up for a mistake in both private and professional settings.

At least six times in public, Clinton apologised for the scandal, later admitting that his initial apology lacked the sense of regret that many Americans were seeking.

'On behalf of your fellow Americans, I extend a sincere apologies to you for the actions that wrongfully deprived Japanese Americans and their families fundamental liberties during World War II,'' begins the passage from President Bill Clinton's letter of apology to Japanese Americans who were moved.

Therefore, Option D is correct.

The digestive system changes the food we eat into usable and unusable materials. Where do unusable materials go until disposal?

Answers

The process in which the complex and insoluble contents of food are converted into simpler and soluble substances, suitable for absorption and assimilation is called digestion. The food is digested by the digestive system with the help of digestive enzymes. The usable materials are absorbed by the small intestine and the unusable food is passed on to the large intestine where the water is absorbed and moves to the anus for removal. Hence, the digestive system processes food into usable and unusable materials. The usable materials are sent to the body's cells as food and unusable material goes into the large intestine to await disposal.
So, the correct option is 'Large intestine to await disposal'.
