A 2000-kg car moving with a speed of 20 m/s collides with and sticks to a 1500-kg car at rest at a stop sign. Show that because momentum is conserved in the rest frame, momentum is also conserved in a reference frame moving with a speed of 10 m/s in the direction of the moving car.

1. An asset manager anticipates the receipt of funds in 200days, which he will use to purchase a particular stock. The stock he had in mind is currently selling for P62.50 and will pay a P0.755 dividend in 50 days and another P0.75 dividend in 140 days. The risk free rate is 4.2%. The manager decides to commit to a future purchase of stock by going long a forward contract on the stock.
   REQUIRED:
   At what price would the manager commit to purchase the stock in 200 days through a forward contract?          (5 marks)
   Suppose the manager enters into the contract at the price you found in Part a. Now, 75 days later, the stock price is P55.75. Determine the value of the forward contract at this point.                       (5 marks)
   It is now the expiration day, and the stock price is P58.50. Determine the value of the forward contract at this time.         (5 marks)

Based on the readings that concentrate on mercantilism, the Triangle Trade, slave plantations in the colonies, and the effects of the Enlightenment on society. Respond this question in one or two pages:

1. According to Eric Williams, the West Indies' plantation slavery (note that slavery is a form of command economy) played a role in England's transition to a market economy. Keep in mind that most people in England lived as farmers, who were essentially independent of the market, before slavery spread to the Caribbean plantations.

For this assignment, name two and thoroughly explain how slavery helped nurture a shift to the market fixing the economic crisis in England, despite the fact that Williams develops a number of reasons surrounding this.To put it another way, how did slavery in the Caribbean: help create more wage labor in England; more goods for sale; more monetary revenues; or other things necessary for the market to address the economic problem

Balance Sheet 

(b)Microlin Ltd intends sot introduce a new product, T, into the market. This will require an 

investment in machinery costing Sh. 2,400,000. The machinery is estimated to have a useful 

life of four years with a terminal value of Sh600,000.

Additional information

1. Capital allowances will be provided on the machinery at a rate of 12.5% per annum 

on a balance basis. At the end of the useful life of the machinery, a balancing charge or 

allowance will arise equal to the difference between the scrap proceeds and the tax 

written down value.

2. Annual profits from the sale of product T will amount to Sh960,000 before deducting 

depreciation on machinery.

3. Corporation tax at a rate of 30% is payable one year after the end of the accounting 

year in which the tax was charged.

4. An investment in working capital amounting to Sh.240,000 will be required on 

commencement of the project. 

This amount will however be recovered on completion of the project.

1. The start of the project coincides with the company's financial year.

2. the cost of capital is 15% per annum

Required:

Using the net present value (NPV) approach, advice the management on the suitability of 

the project. (10 marks)

As mutações ocorreram durante a exposição ao 5-bromouracil (5BU) na cultura de células de E. coli. A evidência de que um evento mutacional ocorreu é que uma colônia não foi capaz de crescer em meio mínimo, mas conseguiu crescer em meio contendo arginina.

what can  be the disease to that person if he is suffering from headache , red eyes, seems like it is burning from inside, feeling dizziness and weakness

The mutagen 5-bromouracil (5BU) was added to a rapidly dividing culture of wild-type E. coli
cells growing in a liquid medium containing a rich variety of nutrients, including arginine. After
one cell division, the cells were washed free of the mutagen, resuspended in sterile water, and
plated onto master plates containing minimal medium supplemented only with arginine. Plates
were obtained having well-separated colonies, so that each colony derived from just one
progenitor cell. The colonies were then replica-plated from the master plates onto plates
containing minimal medium. One colony that grew in the presence of arginine but failed to grow
on minimal medium was selected from the master plate. The cells of this colony were
suspended in sterile water, and each of 20 tubes containing minimal medium supplemented
with arginine was inoculated with a few cells from this suspension. After the 20 cultures grew to
a density of 108

cells/mL, 0.1 mL from each was plated on plates containing minimal medium.
The following table shows the number of bacterial colonies that grew on each plate.

a. In which stage(s) of this process did mutations occur? What is the evidence that a mutational
event occurred?
b. At each stage where mutations occurred, were the mutations induced or spontaneous? Were
they forward or reverse mutations?
c. At each stage where mutations were recovered, how were they selected for?
d. Though all of the 20 cultures started from a single colony that failed to grow on minimal
medium were treated identically, they produced different numbers of bacterial colonies when
they were plated. Why did this occur?
e. Suppose that 5BU had been added to the medium in the 20 tubes. Would plating the 20
cultures have given the same results? If not, how would they have differed?
f. Supposing that methyl methane sulfonate (MMS) rather than 5BU had been added to the
medium in the 20 tubes, answer the questions given above in part (e).

  You will show your work in a written reflection.
  It is up to you how you organize your thoughts into paragraphs.
  Your written reflection should include the following:
  • A brief summary of the issue discussed in the article (max. 2 sentences)
  • How is this related to what we studied?
  • How is this relevant to personal choices or choices a government could make?
  • Any questions left unanswered
  • APA referencing for the article and any other sources of information you use
  These are very basic guidelines. How you write your reflection completely depends on what your article talks about. Feel free to make connections beyond the article to your life, any statistics you find, etc. The connections you make in your reflection to the course content and other relevant issues are much more important than your summary of the article.
