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.

Hope this helps!

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.

If I was asked to create a program for my community I would create an educational event along with brochures for people who want to volunteer their support . Here people would be getting useful tips to continue their lives and clubs would be there , where people can discuss their growth , their income , their spiritual growth and the tips and tricks they use to lead a happy life . This way people would start to develope a friendly nature , a helping attitude and gratitude towards those who helped them . This would help improve the social and moral values of my community . I would also create free red talks on the topics which are most difficult to catch , so that people would be abke to get their hans on resources which are otherwise too expensive to purchase . I would call scholars who are willing to give free support to the community and ask them to provide free lectures . I would provide a certificate to the people who volunteered . This way people in my community will be benefitted and those who volunteered will experience a moment of truth ( in marketing it is said to be a way in which someone becomes a trusted or loyal member of a program or organization ) . To keep my community people involved in my program I would give some freebies that are attractive to sight so that they would frequent my program .

Describe three small changes that you can make to your current eating habits to support a healthier lifestyle. Be specific. Use the Internet if you need to do additional research.

Answers

Answer:

Explanation: Drinking water, eating vegetables, laughing more, and walking around your neighborhood.

Answer:

Any individual can become healthier by following these steps:

Increasing their level of activity: It is important to keep oneself active. A sedentary lifestyle isn’t healthy. A person can make small changes, such as choosing the staircase over an elevator. It helps to have a regular exercise routine. Adults should exercise for at least 30 minutes, five days a week, or at least 2.5 hours per week. Children should exercise for at least an hour daily. The exercise can be vigorous or of moderate intensity—walking, lifting weights, running, playing sports, or aerobics. The exercise should be vigorous enough to lead to an elevated heart rate and sweating.

Eating a healthy, balanced diet: A person’s diet should contain food from all the major food groups—fruits, vegetable, grains, proteins, and dairy. A balanced diet is one that provides all the essential nutrients—carbohydrates, protein, fat, vitamins, and minerals. Choose low-fat, low-calorie items from each of the major food groups. The Dietary Guidelines for Americans and MyPlate offer good guidelines. According to the Dietary Guidelines, the recommended daily calorie count for adult women is 1,800 to 2,200 calories, and for adult men, 2,400 to 2,800 calories. Less active people can refer to the lower limit, while more active people should look at the upper limit.

Controlling stress: When people have a lot of stress in their life, they are likely to suffer from conditions such as headache, anger problems, drug abuse, eating disorders, and fatigue. They should address the reasons for the stress. For example, a person who is stressed due to financial reasons should plan and budget to minimize bills. If they have friends that stress them out, they should avoid interacting with them. For stressors that may not be in a person’s control, such as work pressure, they should learn coping techniques, such as deep breathing or visualization.

Quitting unhealthy habits: Unhealthy habits, such as smoking, abusing alcohol, or using drugs go against the principles of a healthy lifestyle. These habits have a negative effect on health. They increase the risk of cancer, decrease mental capacity, and affect mood. If people are unable to quit these habits on their own, they should contact a doctor or addiction specialist to help them come up with a plan to help them quit.

Developing 'tolerance' to a certain drug means:
A: The acceptance of addicts in society
B: Needing more of a drug to get the same effect
C: The ability to withstand a drug's side effects
D: Ingesting a drug in larger quantities than is saie

Answers

Answer:

D

Explanation:

A persons tolerance goes up the longer they do the drug

Developing tolerance to a certain drug means needing more of a drug to get the same effect

Drug tolerance occurs when a drug does not have the same effect it used to have on a person taking the drug. As a result, the person would have to take more of the drug to get the same effect.

For example, A person takes one pill of a sleep drug and sleeps soundly. If the person develops a tolerance for the drug, the person would need to take more pills.

Drug tolerance occurs as a result of taking the drug too frequently.
