The magnetic flux through a 10.0-cm2cm2 loop is 8.0 T⋅cm2T⋅cm2, and the magnetic field at the location of the loop is uniform. Choose all correct answers.
Check all that apply.
| A)If BB = 1.0 TT, then the angle between the B⃗ B→ field and the normal to the loop's surface is greater than 0∘∘. |
| B)If the direction of B⃗ B→ field is parallel to the normal to the loop's surface, then BB = 0.8 T. |
| C)The magnitude of the B⃗ B→ field must satisfy the condition B≤B≤ 0.8 T. |
| D) The direction of the B⃗ B→ field cannot be perpendicular to the surface of the loop. |
I thought it was just B and D but apparently I'm wrong, can someone explain?
In: Physics
A 2000 V single-phase synchronous generator is being used as a
backup
generator outside a diagnostic center. When the generator
terminals are short-circuited and a field excitation current of 2.5
A is passed, the
ammeter between the terminals read 100 A of full load current. If
the terminals
of the same generator are opened and the voltage across them is
measured using
a voltmeter, we get the value of 500 V with the same excitation
current. The
armature resistance is 0.8 ohms.
Determine the voltage regulation of this generator if it is
delivering 100 A
during normal operation with unity power factor, 100 A with 0.8
leading PF,
and with 0.71 lagging PF.
(Hint: Synchronous Impedance = (0.C Voltage) / (S.C Current))

Case:
Carl Kelly is an American transpatriate assigned to Motorola’s facility in a former USSR satellite nation in Eastern Europe, called Ruritania. Carl has found that Ruritanian culture strange and experienced a bit of culture shock, which explains why he arranged to have his wife Kathleen join him as soon as possible. Kathleen arrived in Ruritania 10 months ago, eagerly looking forward to spending more time with Carl than was possible back in Florida. She was rudely surprised. In those 10 months she was able to spend “quality” time with him on exactly 7 weekends!
Then came some good news. Last month Carl was told that for the next four weeks you would be assigned to Surabaya, Indonesia. Kathleen, who had a long-standing interest in Javanese arts, wanted to go along. That way, on weekdays she could enjoy local music, dance, drama, painting and sculpture, and on weekends she and Carl could finally snatch some quality time together in nearby Bali.
But there was a problem. All three of the Kelly children were in college, and their combined tuition payments were huge financial burden, making it difficult to afford Kathleen’s airfare to Indonesia.
Yaroslav, a Ruritanian colleague of Carl’s, offered to help them out. Yaroslav got in touch with Easy Virtue Travel, a most obliging local company. That evening Easy Virtue delivered to round-trip coach tickets to Surabaya for Carl and Kathleen, along with a bill for just one round trip “business-class” passage for Carl. This way, Carl would bill Motorola for business-class reimbursement, while he and Kathleen would fly coach. Carl would be personally out-of-pocket only an extra $27.94 for Kathleen’s seat. “Not bad,” exclaimed Carl. “That will make up for all of those lonely weekends,” added an eager Kathleen.
That night, though, Carl had trouble sleeping. “Deserve it or not, this is probably against some corporate regulation. I better check with Sam.”
Sam Smoothover was Motorola’s HR manager for Ruritania. Sam had long experience in the former satellite countries and suspected that local Ruritania travel agencies often did things that were technically frowned upon by foreigners, yet actually humane in their consequences. Sam also enjoyed an enviable reputation for putting the well-being of Motorolans high on his list of value priorities – certainly higher than formal compliance with the details of regulations set by headquarters 4,000 miles away.
Sam’s reaction was, “Okay, Carl, you and Kathleen make the trip this time. I just don’t go around talking to people about it.”
However, a few days later Sam had his own second thoughts and decided to check with corporate officials in Schaumburg, just to make sure it really was okay.
Additional information for the case:
Motorola allows for business travel for any trip over five hundred miles so Carl could travel with a business class ticket. The home office also recognizes that the Ruritania assignment is difficult given the primitive living conditions there and that unlike several of his predecessors Carl has done an exceptional job meeting the requirements of the company.
Answer the following questions.
1. What is the issue?
2. Do you think that the travel plan for Carl and his wife appropriate? Why?
3. What are your thoughts regarding Sam Smoothover's response to Carl? What would you have done?

Here is an example of T-test down blow (it doesn't have to be exactly) I need to help with my data which it is about phone service survey. Please help and I really appreciate your time.
T-test looked at how far people travel to visit a healthcare clinic compared to how easy it was to understand the information that their physician was explaining to them (Table 2). The sample group was divided into two categories: people who travel less (?5 miles) and people who travel more (?6 miles). Table 2 shows that, on average, people who travel less understood more information that their physician was explaining to them than the people that traveled more (people who travel less = 4.63, people who travel more = 4.10, p = .026). The conclusion that could be drawn from this finding is that physicians who work in clinics close to dense populations are better at explaining information to their patients. This could be due to these physicians seeing more patients with similar conditions, making it easier for them to explain information to their patients with similar conditions.

Case Study: Omega College
Omega College is a private liberal arts college located in a small
town in the Midwest. The closest large city is about fifty miles
away. There is a community college in the next town about twenty
miles away. Most faculty and staff live in the town or in small
towns nearby.
Originally a Protestant-affiliated institution, Omega is now a
completely independent institution and receives no funding from the
church. It was founded in the late 1800s to meet a pressing need
for teachers in the state. Until recently enrollment at Omega has
been relatively stable, with average enrollment of 850 full-time
undergraduates, some limited programs for part-time students, and a
very limited master's degree program in education focusing on
certification issues in the state. Undergraduates come to Omega
from nearby states, although there is a smattering of students from
other areas of the country. There is a very small international
student enrollment and most international students study at Omega
for a semester and then return home.
Omega has a robust information site on U-Can (the University and
College Accountability Network). The cost of tuition is $25,000 for
the academic year and room and board is an additional $7800 for two
semesters. About 70% of the full-time students who attend Omega
receive some type of financial aid (state, federal, and/or
institutional).
In each of the last four years the freshman enrollment has missed
the target by about twenty students. To offset that enrollment
drop, the admissions staff developed an outreach program to the
nearby community college to encourage transfer students, but most
of the community college transfer students go to the regional
campus of the state university to complete their bachelor's degree.
There is a nearby military base, but students rarely come to Omega
from that source. The average enrollment over the last four years
has dropped to 800 full-time students. This is of concern for many
reasons, not the least of which is the financial health of the
institution.
Omega has a very limited endowment (most of which is earmarked for
student financial aid, some academic departmental support, and
three endowed professorships) and thus is very dependent on
undergraduate tuition to meet the day-to-day operating expenses of
the institution. Graduate tuition for the part-time teacher
certification program is a financial plus for the
institution.
An annual fund program is essential to the fiscal health of the
institution and relies on the generosity of board members, alumni,
and friends of the institution to help fund the annual operating
budget. The decline in enrollment has caused the institution to
reduce nonessential budget expenditures, and faculty and staff have
not received a raise for the past two years. Obviously, Omega
College is just holding on and a new approach to financing the
ongoing expenses of the institution is needed.
The institutional administration and faculty and the governing
board are currently focused on development of a strategic plan for
the institution that deals with both the financial and enrollment
questions. The strategic planning committee is charged with the
following responsibilities:
1.The development of a five-year financial
plan for the institution.
2.The development of an academic plan that
increases the options and opportunities for students to come to
Omega College at the undergraduate and graduate levels.
3.The development of an aggressive institutional
advancement plan. As the committee does its work the college
administration must work to stabilize enrollment and keep the doors
of the institution open.
What other actions might you recommend that the institution consider for the short term?

For New Year’s Eve, Florence has plans to visit her mother and sister, about 100 miles away. This was a good opportunity to show her mother and her sister what she has been working on in the last few months. So, she decides to take Catchmenot with her. She packs her car the evening before and on the morning of the trip, she passes by the lab to get her robot and put it in the car. She drives the 100 miles in a little under her usual time and arrives at her mother’s house earlier than usual”. “In the evening, Florence bids her mother good-bye and passes by her sister’s apartment as promised. At her sister’s apartment, she finds a few of her teen friends and they get right into a party mode. Florence drinks and dances and forgets about the time.

SMITH FAMILY'S 2018 TAX SCENARIO
Joseph L. Smith (age 45, Social Security number 145-26-9210) and Rita M. Smith (age 43, Social Security number 142-46-5108) are husband and wife. They live at 1650 Belmont Avenue, Chicago, IL 60615. David is a self-employed CPA and Rita is a third grade teacher. They have two children: Blake (age 5, Social Security number 310-51-2108) and Amelia (age 3, Social Security number 314-62-8924).
In 2018, Joseph earned $182,000 and Rita earned $46,000. The Smith family has medical coverage through the school system for which Rita works. As an employee, Rita had $9,500 of federal tax withheld, $2,300 of IL state tax withheld, and the required Social Security and Medicare taxes.
Joseph has an office with business expenses for 2018 as follows:
| Item | Amount |
|---|---|
| Office Rent | $24,000 |
| Office Supplies | $8,000 |

Joseph purchased a 2017 Honda Civic in 2017. In 2018, he drove 24,000 business miles and 6,000 personal miles, and uses the standard mileage method for tax purposes.
In 2018, Joseph made estimated quarterly federal tax payments of $18,000/quarter and estimated quarterly IL state tax payments of $3,000. All the payments were made within calendar 2018. Joseph also contributed $8,000 to his SEP account.
Rita bought various supplies for her classroom, but did not closely track expenditures and thus only wants to take the allowed educator expenses deduction. Her teacher's license was also renewed in 2018 for $125.
Blake and Amelia are both in day care at the Riley Day Care Center at 1325 Lake Street, Chicago, IL 60612 (EIN 36-2875647). They are only in day care for 9 months of the year (weekly charge of $240.00/week), because Rita does not work during the summer.
In addition to the wages and expenses as detailed, the Smiths have the following documented income and expenses:
| Item | Amount |
|---|---|
| Interest income from CDs | $1,800 |
| Interest Income from Series EE | $4,000 |
| Government Bonds Mortgage Interest on Principal Residence | $15,000 |
| Property taxes on Residence | $8,000 |
| PMI Insurance Payments | $3,000 |
| Cash Charitable Contributions | $2,500 |
| Non-Cash Contributions (Used Clothing to Salvation Army) | $350 |
The Smiths itemized deductions in 2017. The federal tax refund was $3,500 and the IL state tax refund was $600.
In addition, the Smiths own rental property (a "two flat" in Chicago) which they have rented out for the entire year. Total rental income was $30,000. Rental property related expenses were as follows:
| Item | Amount |
|---|---|
| Mortgage Interest on Rental Property | $13,000 |
| Property Tax | $9,000 |
| Repairs on Rental Units | $2,6000 |
