An ideal spring is lying horizontally on a frictionless surface. One end of the spring is attached to a wall. The other end is attached to a moveable block that has a mass of 5 kg. The block is pulled so that the spring stretches from its equilibrium position by 0.65 m. Then the block is released (from rest), and as a result the system oscillates with a frequency of 0.40 Hz (that's 0.40 rev/sec) Find:

                Show all your steps

a) The acceleratiuon of the block when the spring is stretched by 0.28 m.

b) the maximum force magnitude exerted by the spring on the block.

c)the oscillation frequency of a 2.5 kg blcok under the same circumstances (i.e. with the same spring and initial displacement).

Why does an ETO operation consider product and process design as a production activity? How does it complicate the production planning and control process?

What is the function for printVector that takes a vector of ints, and prints the values one after the other to screen, with commas in between the values.

For example,

vector<int> numbers{0,3,9};
printVector(numbers);

...should print out:

0,3,9

• This week, Super-Save Supermarket lowered the price of apples from $1 to 90 cents per pound. The quantity of apples sold last week was 200 pounds. This week, the quantity sold was 250 pounds. Calculate the price elasticity of demand. Is it elastic, inelastic, or unitary elastic? What happens to total revenue?
• Using the information given in the previous question, assume that last week Super-Save Supermarket sold 150 pounds of bananas and this week it sold 120 pounds of bananas. Are bananas and apples complements or substitutes? What is the cross elasticity of demand?

My elasticity is equaling 2. I'm I correct or I'm missing something?

Discuss the role of nursing in implementing music listening/therapy in hospitals. How can nurses impact, support, and sustain the change. (Write half a page)

Plan, Do, Study, Act (PDSA): Design test of change- In a perfect world, how would you go about using the PDSA cycle to implement music therapy?

Consider the following project data: A Shs 4 million feasibility study will be conducted at t =0. If the study indicates potential, the firm will spend Shs 20 million at t= 1 to build a prototype. The best estimate is that there is an 80% chance that the study will indicate potential and 20% chance that it will not. If reception of the prototype is good the firm will spend Sh. 700 million to build a production plant at t=2. The best estimate is that there is a 70% chance that the prototypes’ reception will be poor. If the plant is built, there’s a 60% chance of a t=3 cash inflow of Shs 600 million and a 40% chance of Shs 300 million cash inflow. If the inflow at t=3 is Shs 600 million, there are 30% and 70% chances of Shs 320 million and Shs 180 million inflows respectively at t=4. If the inflow at t=3 is Shs 300 million, there are 80% and 20% chances of Shs 420 million and Shs 280 million inflows respectively at t=4. The plant has a salvage value of Shs 100 million at t=5.

If the appropriate cost of capital is 14% what is the project’s expected NPV?

Suppose some FSM has 3 inputs, internal Ready, external bus-grant Grant, and external bus-free Free signals, as well as 2 outputs, bus-request Req and bus-lock Lock signals. Show its Moore-type state diagram, assuming that the FSM implements the following bus protocol: (1) initially, the FSM outputs Req = 0 and Lock = 0 and waits for both Ready and Free to be asserted; (2) After receiving Ready = 1 and Free = 1, the FSM outputs Req = 1 and Lock = 0 and waits for Grant to be asserted; (3) After receiving Grant = 1, provided that both Ready and Free still equal 1, the FSM outputs Req = 0 and Lock = 1 and waits for Ready to become 0; once Ready = 0, the FSM returns to step (1).
NOTE: Should Ready and/or Free become 0 while waiting for Grant = 1, the FSM returns to step (1). The FSM ignores the Grant input in steps (1) and (3), and it ignores the Free input in step (3).

Create a class named TelpaMotion.

               The inMotion field must not be accseible outside of the class. This fields can be initialized 3 different ways.

                              Default 67 mulltiplied by the value of 9.80665

                              A value being passed to it

                              A starting value and an acceleration rate can also be passed, the value should be multiplied by the acceleration rate to set the initial value.

               Create a static field called tractionValue with a default value of 0.33.

                    In the same class create a public method called OverCompensate which allows your team to increase and return a result by multiplying the inMotion value by 1.5 and adding the tractionValue to the result (i.e. (inMotion *1.5)+tractionValue)

In your main method:

Call your class:

               TelpaMotion optionA= new TelpaMotion();

               TelpaMotion optionB= new TelpaMotion(100.45);

TelpaMotion optionC= new TelpaMotion(27.9, 0.321);    

Using the object created for option c, call the OverCompensate method to assign the calculated value to a variable called emergencyStop and display the results. Option created Display to the console the results of each call to the class

A duty of Directors

1) Tasty Treats Ltd (a Restaurant) is negotiating with Renovations center Ltd. (a construction company) for the renovation of Tasty Treats Ltd's Premises. Sash the owner of Renovations Center Ltd is also one of the five members of the board of directors of Tasty treats Ltd. The contract terms for the Construction are Standard, and the Price set for the renovations contract is fair. Sash has previously informed two of the price set for the other directors of Tasty Treats Ltd. of her ownership in Renovations contract on a three-to-two vote, with Sash voting with the majority.

Discuss the following

a) explain fully the law governing this matter (choose the appropriate duty)

b) explain whether correct procedure was followed

c) explain whether this contract is binding on the two companies

D) give a full conclusion and analysis of the matter

An accounting firm noticed that of the companies it audits, 85% show no inventory shortages, 10% show small inventory shortages, and 5% show large inventory shortages. The firm has devised a new accounting test for which it believes the following probabilities hold: P(company will pass test | no shortage) = .90 P(company will pass test | small shortage) = .50 P(company will pass test | large shortage) = .20

a. If a company being audited fails this test, what is the probability of a large or small inventory shortage?

b. If a company being audited passes this test, what is the probability of no inventory shortage?
