Answer:

The speed of the car is 67.77 m/s and it is moving away from the observer.

Explanation:

The apparent frequency is given as

f' = f\dfrac{ [v - vo]}{ [v - vs]}

Here

o is the  observer

s is the source which is car

v is the speed of  sound  = 343 m/s

f = true frequency emitted by the car (when stationary)

f ' = 0.835 f

so

f' = f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 f= f\dfrac{ [v - vo]}{ [v - vs]}\\0.835 = \dfrac{ [343 - 0]}{ [343 - vs]}\\0.835=\frac{343}{343-x}\\x=-67.77 m/s

The speed of the car is 67.77 m/s and it is moving away from the observer.

Ivenika [448]

<u>Full question:</u>

On June 15, Harper purchased equipment for $100,000 from Imperial Corp. for use in its manufacturing process. Harper paid for the equipment with funds borrowed from Eastern Bank. Harper gave Eastern a security agreement and financing statement covering Harper’s existing and after-acquired equipment. On June 21, Harper was petitioned involuntarily into bankruptcy under Chapter 7 of the Federal Bankruptcy Code. A bankruptcy trustee was appointed. On June 23, Eastern filed the financing statement. Which of the parties will have a superior security interest in the equipment?

A. The trustee in bankruptcy, because the filing of the financing statement after the commencement of the bankruptcy case would be deemed a preferential transfer.

B. The trustee in bankruptcy, because the trustee became a lien creditor before Eastern perfected its security interest.

C. Eastern, because it had a perfected purchase money security interest without having to file a financing statement.

D. Eastern, because it perfected its security interest within the permissible time limits.

<u>Answer:</u>

Eastern parties will have a superior security interest in the equipment because it perfected its security interest within the permissible time limits.

<u>Explanation:</u>

Eastern has a higher security interest because Eastern amended its security interest inside the allowable time deadlines. A perfected security interest in any security interest in an asset that cannot be demanded by any other party.  

Below the Uniform Commercial Code (U.C.C.), to perfect a security interest, a lender has 10 days from the date of the sale of material to perfect the security interest by filing a financing statement.  Possessing registered in the 10-day limit, Eastern has a strong perfected security interest in the material and after-acquired things even though the bankruptcy was recorded two days ahead.

Hoochie [10]

Answer:

Annual depreaciation 2020= $2,400

Explanation:

Giving the following information:

Purchase price= $12,000

Salvage value= $2,000

Useful life= 5 years

<u>To calculate the depreciation expense under the double-declining balance, we need to use the following formula:</u>

Annual depreciation= 2*[(book value)/estimated life (years)]

2019:

Annual depreaciation= 2*[(12,000 - 2,000) / 5]

Annual depreaciation= 4,000

2020:

Annual depreaciation= 2*[(10,000 - 4,000) / 5]

Annual depreaciation= $2,400

Alliance Company budgets production of 35,000 units in January and 39,000 units in the February. Each finished unit requires 4 p
harkovskaia [24]

Answer:

$506,800

Explanation:

The calculation of budgeted materials cost is shown below:-

For computing the budgeted materials cost first we need to find out the total materials for production and materials to be purchased which is here below:-

Total materials for production = Budgeted production × Pounds of raw material per unit

= 35,000 × 4

= 140,000

Materials to be purchased = Total materials for production + Ending raw materials inventory - January 1 inventory

= 140,000 + (39,000 × 4 × 30%) - 42,000

= 140,000 + 46,800 - 42,000

= 186,800 - 42,000

= 144,800

Budgeted materials cost for January = Materials to be purchased × Cost per pound

= 144,800 × $3.50

= $506,800
