What does a star–delta starter used with an induction motor do

1. Atwo-pole 60 Hz induction motor has a slip of2%on full load. The full-load

 

speed is

(a) 58.8 r/s (b) 3528 r/min

(c) 60 r/s (d) 2880 r/min

2.The slip of an induction motor can never be zero in a stable state because

(a) the rotor would be at standstill

(b) induced EMF and rotor current would be excessive

(c) it would then be a synchronous motor

(d) there would be no rotor EMF, rotor current or torque

3. The torque provided by the rotor of an induction motor is at a maximum when

(a) speed is maximum

(b) rotor resistance equals rotor reactance

(c) the connected mechanical load is at a minimum

(d) starting

4. If an electronic speed controller feeds an induction motor, the machine….

What would you have been thinking to yourself during the periods of silence?

Using Silence in Counseling

The following exchange between Carol and her counselor illustrates how important silence can be in a crisis. Carol is an adult female who presented to counseling with severe symptoms of depression, suicidal ideation, and an attempt to kill herself yesterday with an overdose of sleeping pills.

Carol: I just want to die. All of the emotional pain, sadness, and humiliation. I just had another miscarriage, my third one, and I’m almost certain I’ll never have children. (Pauses for 15 seconds to think.) On top of that, my husband is growing more distant too, and I worry he might leave me for someone who he can have a family with.

Counselor: So you’re also feeling worried about how this is going to impact your marriage,….

What facts surrounding the death of her fiancé made recovery more difficult?

A Case of Bereavement-Related Withdrawal

Shayna, a woman in her mid-20s, presented for counseling several months after the death of her fiancé, Jerod, from a rare viral infection. While hospitalized for the virus, Jerod had a heart attack, lapsed into a coma, and died several days later. He was 25 years old. Shayna was distraught, as was Jerod’s family. The death was completely unexpected—and making sense of it was deferred for months as they awaited autopsy results. It was only after the autopsy that they discovered that a rare and fatal virus had crystallized in Jerod’s organs, and one by one his organs failed. Even then, the cause of death was not fully comprehensible. It did not make sense.

His mother and father were in their 40s; his….

Assessing for Level of Threat: Judy

Judy is a 43-year-old single woman who has been placed on 2 weeks’ administrative leave from her job as a research and development technician at a chemical company. Over the years, she has had many personality conflicts with other workers, but her expertise is valuable, and these conflicts have always been smoothed over and worked out. Recently, she “lost it” with her boss and flew into a rage when she was denied time off in compensation for working late the previous week; this incident was the basis for her administrative leave. Her family doctor has prescribed antidepressants for her and has referred her to you for counseling.

Judy expresses anger and a sense of hopelessness about her situation. She is distraught and….

f you think there are good arguments for, or a proof of, God’s existence, state the arguments or the proof and defend it against your atheist friend’s objections.

If you believe in God, try to explain to an atheist friend (real or imagined) why you believe in God.

• If you think there are good reasons for believing, state them.

• If you think there are good arguments for, or a proof of, God’s existence, state the arguments or the proof and defend it against your atheist friend’s objections.

• If you think that the only way to believe in God is through faith, answer your atheist friend’s objections that you are being irrational, that you are simply indulging in “wishful thinking,” and that you are escaping from your responsibilities to change the world and, instead, are accepting a fantasy in which God will take full responsibility

Choose one of the elements defended by the pre-Socratic philosophers (water, fire, numbers, and so on) and argue for it as well as you can, preferably with a friend or a few friends who will try to prove you wrong.

Choose one of the elements defended by the pre-Socratic philosophers (water, fire, numbers, and so on) and argue for it as well as you can, preferably with a friend or a few friends who will try to prove you wrong. For example, if you choose fire, an immediate objection would be that fire could not possibly be the essential element in cold objects—a block of ice, for example. A reply might be that cold objects simply contain much less fire than hot things. You might also argue that not all fire manifests itself as flame, and soon, no doubt, you will find yourself moving into more modern-day talk about energy instead of fire as such. The point of the exercise is (1) to see how very much alive….

What is the net present value of the proposed mining project? Should the project be accepted?

Net Present Value Analysis Windhoek Mines, Ltd., of Namibia, is contemplating the purchase of equipment to exploit a mineral deposit on land to which the company has mineral rights. An engineering and cost analysis has been made, and it is expected that the following cash flows would be associated with opening and operating a mine in the area: The mineral deposit would be exhausted after four years of mining. At that point, the working capital would he released for reinvestment elsewhere. The company’s required rate of return is 20%. Required: What is the net present value of the proposed mining project? Should the project be accepted? Explain.

 

What should the court decide?

An employee was hired as general manager of a new assisted-living facility. For several months, she received positive feedback on her progress. At a meeting, two supervisors inquired about her child-rearing plans. She admitted that she planned to have children and was fired two weeks later. She was replaced by a 60-year-old woman. Her supervisor’s manual included a policy on progressive discipline that was generally adhered to. However, she also received and signed a disclaimer that stated in part: “I understand that [neither] the policies and procedures of the facility, nor the Handbook . . . are intended to constitute a contractual agreement. …I understand that my employment is ‘at will.’ …” What should the court decide? Why?
