Answer:

B = 0.287  Tesla

According to thumb rule the direction of magnet is to the east.

Explanation:

F = BiL sin∅

note that F = mg

B = magnetic field

i = current

therefore,

mg = BiLsin∅

Make B subject of the formula

B = mg/iLsin∅

m/L = mass per length of the wire and it is given in gram per centimeter . It should be converted to kg per meter.

m/L = 0.440 g/cm

convert to kg/m = 0.440 × 0.001 kg × 100 m = 0.044  kg/m

B = 9.8 × 0.044 / sin 90 × 1.50 × 1

B = 0.4312/ 1.50

B = 0.28746666666

B = 0.287  Tesla

According to thumb rule the direction of magnet is to the east.

Automatic stabilizers refer to:
Aliun [14]

Answer:

B) government spending and taxes that automatically increase or decrease along with the business cycle.

Explanation:

The two most common automatic stabilizers are: income taxes and unemployment benefits.

When the economy is strong, people make more money, and income tax revenue automatically increases.

On the contrary, when the economy is weak, or in recession, people earn less, and more of them are unemployed. Unemployment benefits therefore increase accordingly.

Hairston Industries has $5 million of debt and $20 million of equity. If Hairston's beta is currently 1.75 and its tax rate is 4
nasty-shy [4]

Answer:

The un levered beta ( bu) of the company is 1.52

Explanation:

Given information -

Equity  (E) - $20 million

Debt (D) - $5 million

Beta ( levered ) - 1.75

Tax rate ( T ) = 40%

D / E ( Debt to Equity ratio ) = $ 5 million / $20 million = .25

Formula for taking out un levered beta ( bu) is -

Beta levered ( bl ) = Beta un levered ( bu ) [1 + (1 - T ) D / E ]

1.75 = bu [1 + (1 - 40% ) .25

1.75 = bu [1 + .6 x .25 ]

1.75 = bu [ 1 + .15 ]

1.75 = bu [ 1.15 ]

bu = 1.75 / 1.15

bu = 1.52

Julie and Barry Spinos purchased a house for $96,400. They made a 25 percent down payment and financed the remaining amount at 5
Alinara [238K]

Answer: $79.30

Explanation:

Cost of the house = $96400

Down payment = 25% × $96400 = $24100

Mortgage = $96400 - $24100 = $72300

Interest = 5.5%

Time = 5 years

Monthly payment.= $410.66

The interest for first payment will be:

= $72300 × 5.5% × 1/12

= $72300 × 0.055 × 0.08333

= $331.36

Therefore, the amount of the first monthly payment is used to reduce the principal will be:

= $410.66 - $331.36

= $79.30
