A horizontal pipe carries a smoothly flowing liquid with density 1.39 × 103 kg/m3. At locations 1 and 2 along the pipe the diameters are 5.23 cm and 2.19 cm, respectively. The flow speed at location 1 is 1.79 m/s. What is the pressure difference between location 2 and location 1 (including its sign)? Ignore viscosity.

Suppose Torche Corporation has the following results related to cash flows for 2018:

Net Income of $8,500,000

Decrease in Accounts Payable of $400,000

Increase in Accounts Receivable of $800,000

Increase in Debt of $100,000

Depreciation Expenses of $1,600,000

Purchases of Property, Plant, & Equipment of $5,400,000

Assuming no other cash flow adjustments than those listed above, create a statement of cash flows with amounts in thousands.

What is the Net Cash Flow?

Please specify your answer in the same units as the statement of cash flows.

A hockey player is standing on his skates on a frozen pond when an opposing player, moving with a uniform speed of 2.0 m/s, skates by with the puck. After 2.60 s, the first player makes up his mind to chase his opponent. If he accelerates uniformly at 0.36 m/s², determine each of the following.

(a) How long does it take him to catch his opponent? (Assume the player with the puck remains in motion at constant speed.)
                     s

(b) How far has he traveled in that time?
                       m

In a titration, 0.140 M HBr is titrated by 0.100 M NaOH. If 16.00 mL of the NaOH titrant is added to 20.00 mL of the HBr solution (followed by mixing), what is the pH of the resulting solution?

Montgomery Corp is currently worth $30 million as a company, but has $50 million of debt. There is a potential project that costs $60 million that would require shareholders to provide an additional $30 million to invest in. In one year, the project will yield $99 million or $55 million with 50% probability each. If the investment is not made, the firm will file for bankruptcy today. Suppose a 10% discount rate.

The shareholders will _____ the investment because they stand to _____. The investment is _____ for the firm and _____ for the debtholders.

(Ignore taxes and bankruptcy costs)

What drives the current regional conflicts in the world? Can alternatives to war be found and accepted?

In java, implement an animal guessing game. Start with a "Decision Tree", but present the leaves as “Is it a X?” If it wasn't, ask the user what the animal was, and ask for a question that is true for that animal but false for X. For example,

Is it a mammal? Y
Does it have stripes? N
Is it a pig? N
I give up. What is it? A hamster
Please give me a question that is true for a hamster and false for a pig.
Is it small and cuddly?

In this way, the program learns additional facts.

Once complete, add to the program by writing the tree to a file when the program exits. Load the file when the program starts again.

In a quiz show a uniformly random integer r between 1 and 10 is generated. Another, independent such random numbers will then be generated, but before that happens, you are invited to guess whether s will be greater than or less than r. If you are correct, then you win s pounds. If you lose (or if s = r) then you win nothing. (i) Clearly if r = 1 you should guess that s will be larger. And if r = 10 you should guess that s will be smaller. At which value of r should your strategy change from guessing s will be larger to guessing it will be smaller? (Your aim, as always, is to maximise your expected gain.) (ii) Suppose now that the range of possible values for r and s is 1, ... , N. Then in the limit as N tends to infinity the change of strategy should happen at a value of r of approximately N/k. Find the value of k.

You have two glasses of water each with equal amount of it. In glass “A” the temperature of the water is 10 ◦C. In glass “B” the temperature of the water is 30 ◦C. (4/20 credits)

b) The water in glass B has more internal energy c) They have equal amount of internal energy

Problem 5-50 Activity-Based Costing; Analysis of Operations (LO 5-1, 5-2, 5-4, 5-5, 5-7, 5-10)

Grady and Associates performs a variety of activities related to information systems and e-commerce consulting in Toronto, Canada. The firm, which bills $160 per hour for services performed, is in a very tight local labor market and is having difficulty finding quality help for its overworked professional staff. The cost per hour for professional staff time is $70. Selected information follows.

• Billable hours to clients for the year totaled 8,000, consisting of information systems services, 4,800; e-commerce consulting, 3,200.
• Administrative cost of $411,760 was (and continues to be) allocated to both services based on billable hours. These costs consist of staff support, $220,200; in-house computing, $155,000; and miscellaneous office charges, $36,560.

A recent analysis of staff support costs found a correlation with the number of clients served. In-house computing and miscellaneous office charges varied directly with the number of computer hours logged and number of client transactions, respectively. A tabulation revealed the following data:

Required:
2. Assume that the firm uses traditional costing procedures, allocating total costs on the basis of billable hours. Determine the profitability of the firm’s information systems and e-commerce activities, expressing your answer both in dollars and as a percentage of activity revenue.
3. Assume that the firm uses activity-based costing. Determine the profitability of the firm’s information systems and e-commerce activities, expressing your answer both in dollars and as a percentage of activity revenue.
4. Jeffrey Grady, one of the firm’s partners, doesn’t care where his professionals spend their time because, as he notes, “many clients have come to expect both services and we need both to stay in business. Also, information systems and e-commerce professionals are paid the same hourly rate.” Should Grady’s attitude change?

I need # 3.

If you're writing about a theory with Yang-Mills/Gauge fields for an arbitrary reductive gauge group coupled to arbitrary matter fields in some representation, is it best to call it a Yang-Mills theory or a Gauge theory?

I've heard that one is more likely to refer to a theory with no matter sector - but I can't remember which one! Or are the terms basically interchangeable in the context of quantum field theory?

A rocket is launched at an angle of 53.0° above the horizontal with an initial speed of 98 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 31.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile.

(a) Find the maximum altitude reached by the rocket.

(b) Find its total time of flight.

(c) Find its horizontal range.
