7. A 1100-kg car is moving toward the north along a straight road at a speed of 20.0 m/s. The driver applies the brakes and the car comes to rest in a distance of 140 m.

(a) If the road is completely level, what is the constant force applied to the car to bring it to rest? (Remember to specify the direction.)

(b) If the road goes down a hill at a 4� angle with respect to the horizontal, what is the constant force applied to the car to bring it to rest?

(c) What is the source of the force that brings the car to rest? (In other words, what is exerting the force on the car?) Explain your answer clearly.

Create a script that take a directory path from the user. What I want you to do is figure out the total size of all files in the directory. You will need to import the os module for this.

• dirs=os.listdir(DIRECTORY) where DIRECTORY is the direction you want to look at will return a list of all files in that directory.
• You can then use a for loop to go through dirs much like you went through a range in the previous examples you saw. Start by doing this and printing out the name of each file found.
• Once you have that working create a total variable and use os.path.getsize(FILE) where FILE is the file's size you want to add the file size to total.
• Print out the total size for all files in the directory. Note that the result is in bytes.
• Use an if statement to print the total out in KB if the total is over 1024. If it is not, simply print the total in bytes.
• Finally add to your program to also calculate the average size of a file in the given directory.

Product innovation includes designing innovative products and getting them to market quickly. In a world where the design, production, and consumption may be on different continents, describe how an ERP system help facilitate product innovation.

The Lifang Wu Corporation manufactures two models of industrial robots, the Alpha 1 and the Beta 2. The firm employs 5 technicians, working 160 hours each per month, on its assembly line. Management insists that full employment (that is, all 160 hours of time) be maintained for each worker during next month’s operations. It requires 20 labor-hours to assemble each Alpha 1 robot and 25 labor-hours to assemble each Beta 2 model. Wu wants to see at least 10 Alpha 1s and at least 15 Beta 2s produced during the production period. Alpha 1s generate a $1,200 profit per unit, and Beta 2s yield $1,800 each.

a. How many Alpha 1's should be produced?                            [ Select ]   

b. How many Beta 2's should be produced?                            [ Select ]   

c. What is the overall profit level?                            [ Select ]

d. If the overall hours were increased by 20, how much would the profit increase?

1. Which one of these describes the ecological relationship called symbiosis?

A. corals are large, complex structures built by tiny organisms and consist of their 'shells' and themselves. Some corals' animals are photosynthetic--they house single- celled photosynthetic microorganisms that provide the animal with sugars and other nutrients. The coral animals' bodies give the photosynthetic microbes a sheltered, chemically stable location and provide fresh (not salt) water

B. A fully mature flower is ready to have its pollen spread to other plants of the same kind. A bee lands on the flower, reaches deep into it and drinks sweet nectar. It climbs back out of the flower and, just as it occurred when the bee entered the flower, the hairs on the bee's back and the 'pollen combs' on its hind legs, capture a large amount of pollen. This will end up on the next flower's female structures--this is pollination. The bee and the plant live separate, independent lives

C. mistletoe, a plant that grows as a thick bunch on the branches of trees, penetrates the surface of the branch with special sucking structures that remove water and nutrients from the tree's vascular system

2. Which one of these descriptions of fungi is correct?

A. fungi gain nutrients from decomposing dead animals

B.some fungi grow underground, forming large white masses made up of tangled fungal filaments

C. fungal hyphae are made up of long chains of plant cells

3. Why doesn't chaparral soil contain much decomposed organic material?

A. the plants drop few or no leaves

B. there are no decomposers living in chaparral soil

C. chaparral soil does not have a steady, consistent water content; it is too dry for the organisms that break down (decompose) dead plant material

4. How do fungi spread through soil?

A. very quickly

B. by hyphal extension (i.e., as hyphae grow due to cell division)

C. fungal cells do not move

Chastain Corporation is trying to determine the effect of its inventory turnover ratio and days sales outstanding (DSO) on its cash conversion cycle. Chastain's 2019 sales (all on credit) were $286,000, its cost of goods sold is 80% of sales, and it earned a net profit of 8%, or $22,880. It turned over its inventory 5 times during the year, and its DSO was 38 days. The firm had fixed assets totaling $43,000. Chastain's payables deferral period is 45 days. Assume 365 days in year for your calculations.

1. Calculate Chastain's cash conversion cycle. Do not round intermediate calculations. Round your answer to two decimal places.
     days
2. 
   
3. Assuming Chastain holds negligible amounts of cash and marketable securities, calculate its total assets turnover and ROA. Do not round intermediate calculations. Round your answers to two decimal places.
   

   Total assets turnover:
   ROA:		%

4. 
   
5. Suppose Chastain's managers believe that the inventory turnover can be raised to 9.5 times. What would Chastain's cash conversion cycle, total assets turnover, and ROA have been if the inventory turnover had been 9.5 for 2019? Do not round intermediate calculations. Round your answers to two decimal places.
   

   Cash conversion cycle:		days
   Total assets turnover:
   ROA:		%

How do you find E^o of a cell?

Is the formula E^o cell= cathode - anode?
Or is it E^o= Oxidation + Reduction?

i am very confused as to when I should add the cell potentials together and when I should subtract. If at all possible, please provide examples!

Develop code in a Scala Maven project to monitor a folder in HDFS in real time such that any new file in the folder will be processed .For each RDD in the stream, the following subtasks are performed concurrently: (a) Count the word frequency and save the output in HDFS. Note, for each word, make sure space (" "), comma (","), semicolon (";"), colon (":"), period ("."), apostrophe (“’”), quotation marks (“””), exclamation (“!”), question mark (“?”), and brackets ("[", “{”, “(”, “” ) are trimmed. (b) Filter out the short words (i.e., < 5 characters) and save the output in HDFS. (c) Count the co-occurrence of words in each RDD where the context is the same line; and save the output in HDFS.
