why induced EMF is known as back EMF​

Answers

Answer 1

Answer:

Induced EMF is also called back EMF because, the induced EMF opposes the change in current, due to the source of EMF. The induced current causes a restoring torque in the coil. An external source is responsible for the supply of energy for this torque. So we can say that source of this power is the external rotor.

Answer 2
In electromagnetism and electronics, electromotive force, is the electrical action produced by a non-electrical source. Devices provide an emf by converting other forms of energy into electrical energy, such as batteries or generators. Sometimes an analogy to water pressure is used to describe electromotive force.

How does this level of organization relate to cells? To organ systems?

Answers

Answer:

The heart —belonging to the organ level of organization— is composed of cardiac muscle cells forming the myocardium, and belongs to the cardiovascular system.

Explanation:

The cellular level of organization of the heart is complex, since it is a group of specialized cells that constitute the main organ of the cardiovascular system.

The heart is predominantly made up of the myocardium, formed by muscle cells similar to those of the striated muscle, but with a different distribution. Other cells belonging to the heart are the endothelial cells, which cover its interior, and the fibrous and serous cells that constitute the pericardium.

Structurally, the heart is part of the cardiovascular system, whose function is to carry blood throughout the body. Functionally, this organ is related to all the tissues, organs and systems of the body.

Reaction time is the lapse of time between muscular movement and external stimuli.

describe the three types of energy balance in the body and what each one is used for.​

Answers

Answer:

Explanation:

Lactic Acid System

The lactic acid system, also called the anaerobic glycolysis system, produces energy from muscle glycogen -- the storage form of glucose. Glycolysis, or the breakdown of glycogen into glucose, can occur in the presence or absence of oxygen. When inadequate oxygen is available, the series of reactions that transforms glucose into ATP causes lactic acid to be produced -- in efforts to make more ATP. The lactic acid system fuels relatively short periods -- a few minutes -- of high-intensity muscle activity, but the accumulation of lactic acid can cause fatigue and a burning sensation in the muscles.

Which of the following is NOT a potential side effect of stimulants?
Depressed heart rate
Anxiety
Loss of appetite
Seizure

Answers

The answer is : depressed heart rate

Answer:

The answer is: Depressed heart rate

Stimulants are drugs that act on the body's central nervous system (CNS) in order to elevate mood, increase alertness, and generate a feeling of well-being. Moreover, stimulants also decrease appetite and increase physical activity.

Stimulants can be categorized into 1-legal (e.g., guarana, taurine, and L-carnitine, coffee and nicotine) and 2-illegal (e.g., methamphetamine, crystal meth, cocaine) stimulants. Both types of stimulants may lead to addiction. The abuse of these substances (stimulants) may cause different health problems such as anxiety, depression, cardiovascular diseases, hypertension, insomnia,  aggressiveness, etc. On the other hand, there are prescribed stimulants such as, for example, Ritalin and Adderall, which are used for treating Attention-Deficit/Hyperactivity Disorders (ADHDs). Moreover,  they are also prescribed to promote weight loss or treat depression.

Stimulants drugs can increase the activity of dopamine and norepinephrine neurotransmitters in the brain, increasing alertness, attention, and energy. Stimulants drugs are also known to increase blood pressure. Conversely, depressant drugs (e.g., alcohol) act to decrease the activity of the brain.  

In resume, stimulants function to increase heart rate and blood pressure, leading to negative health effects

I"LL GIVE YOU BRAINLEST!! Write an essay about What can you do personally to stop bullying? What can you and your social group(s) do to stop bullying? How can adults help stop bullying?

Answers

Answer:

Schools are a primary place where bullying can happen.

Learn what bullying is and what it is not. Many behaviors that look like bullying may be just as serious, but may require different response strategies. You can also learn about what to look for as warning signs that some of your students might be involved in bullying and who might be at more risk for being involved. Know about special considerations for specific groups.

Establish a safe school climate. Often the first step to preventing bullying is making sure the students, teachers, and administrators alike are educated about bullying. Tools like the School Bus Drivers Training and Classroom Teacher Training can help. For kids, tools like these webisodes can help them learn about bullying.

Learn how to engage parents and youth in the building a positive school climate. Learning how to talk about bullying with youth is a critical step.

Know about your obligations under your state’s anti-bullying law. Learn also about federal laws that require schools to address harassment based on race, color, national origin, sex, and disabilities. Work to establish rules and policies to help let the entire school community know the expectations around bullying and procedures to report and investigate when something happens.

Assess bullying in your school and understand how your school compares to national rates of bullying.

Respond when bullying happens. Learn how to stop it on the spot, find out what happened, and support all students involved.

Avoid misdirections in bullying prevention and response strategies.

Utilize free Federal and Non-Federal Resources on bullying.

Parents play a key role in preventing and responding to bullying. If you know or suspect that your child is involved in bullying, there are several resources that may help.

Recognize the warning signs that your child is involved in bullying. They could be being bullied, bullying others, or witnessing bullying.  Although these signs could signal other issues, you should talk to your child if they display any sort of behavioral or emotional changes.  Many times kids won’t ask for help, so it is important to know what to look for. If your child is at immediate risk of harming himself or others, get help right away.

Learn what bullying is and what it is not. Understanding what bullying is is the first step in forming a plan to prevent or respond to bullying with your child. Many behaviors that look like bullying may be just as serious, but may require different response strategies. You can also learn about:

The frequency of bullying;

Who is at risk for being bullied and bullying others; and

The effects of bullying

Cyberbullying often requires different strategies than in-person bullying.  Learn how to work with your kids to prevent cyberbullying and how to respond when it occurs.

Utilize tips and tools to talk to your child about bullying. Opening lines of communication before your child is involved in bullying makes it easier for them to tell you when something happens. It is also important to work with a school to help prevent bullying before it starts.

If you know or suspect bullying has occurred, learn how to find out what has happened with your child. Understanding what has happened can also help in communicating with school or community officials about the situation.

If you have determined bullying has occurred, learn how you and school or community officials can work together to support your child, whether they were bullied, bullied others, or witnessed bullying.  Learn also about considerations for specific groups.

If bullying is occurring at school, learn about what your state requires schools to do in your state’s anti-bullying law. Learn also about federal laws that require schools to address harassment based on race, color, national origin, sex, and disabilities and ways to report situations that have not been adequately addressed to the U.S. Departments of Education and Justice.

If you have worked with your child and your school and need additional assistance, find resources to help address the situation.

Explanation:

Answer:

Bullying is not only a topic, but it is an action. An action in which is seen by many everyday within school systems, business offices, or on the streets. It is everywhere and has become part of the everyday environment. More often then not, bullying occurs greatly within local school systems, where it has come to the extent of having individuals remove themselves from the environment over bullying. Bullying can happen in many ways whether it be race, gender, religion, sexual orientation, and the list goes on. It is not something that can be pushed away any longer. Why should children be punished from there education due to another individual? Exactly, there is no reasonable explanation. Many individuals do not understand what it would be like to be on the other end of the stick. Instead of being the bully, you are being the one bullied. Many know that being bullied is not an enjoyment because it has become part of their everyday lives. Much of which is done on the premises of the school building. Gone unknown and unheard. One of the major items that is noticed on what children get picked on is what they wear to school. If it isn’t designer clothes or items that don’t have a name brand plastered across it, they should get judged. Why? It’s not like it’s their fault.
