Question strategic management exam 2. PORTER'S MODEL HELPS WITH THE STRUCTURAL ANALYSIS OF THE TASK ENVIRONMENT WHICH MEANS TESTING THE COMPETITIVE ENVIRONMENT AND UNDERSTANDING THE FORCES AT WORK. HOW DOES THIS MODEL WORK?

One unit of A is composed of two units of B and three units of C. Each B is composed of one unit of F. C is made of one unit of D, one unit of E, and two units of F. Items A, B, C, and D have 20, 50, 30, and 25 units of on-hand inventory. Items A, B, and C use lot-for-lot (L4L) as their lot-sizing technique, while D, E, and F require multiples of 50, 100, and 90, respectively, to be purchased. B has scheduled receipts of 20 units in Period 1. No other scheduled receipts exist. Lead times are one period for Items A, B, and D, and two periods for Items C, E, and F. Gross requirements for A are 20 units in Period 1, 10 units in Period 2, 55 units in Period 6, and 50 units in Period 8. Find the planned order releases for all items.

An object with total mass mtotal = 17.3 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.9 kg moves up and to the left at an angle of θ1 = 20° above the –x axis with a speed of v1 = 25.5 m/s. A second piece with mass m2 = 5.1 kg moves down and to the right an angle of θ2 = 25° to the right of the -y axis at a speed of v2 = 21 m/s. What is the x-component of the velocity of the third piece? What is the y-component of the velocity of the third piece? What is the magnitude of the velocity of the center of mass of the pieces after the collision? Calculate the increase in kinetic energy of the pieces during the explosion.

3. Write Java code for a Baby class. A Baby has a name of type String and an age of type integer. Supply two constructors: one will be the default constructor, which just sets default values for the name and age; the second constructor will take two parameters, a string to set the name and an integer to set the age. Also, supply methods for setting the name, setting the age, getting the name and getting the age. The class should not contain I/O methods; use set method or constructor to set the value passed in as a parameter. The instance variables for output can be obtained using the get methods. The set method for the name instance variable should ensure that the value passed is not empty or contain whitespaces (otherwise set a default value). The set method for the age instance variable should validate the value passed to be between 1 and 4 inclusive (otherwise set a default value). Give Java code for an equals method for the Baby class. Babies count as being the same (i.e. equal) if their names and their ages are exactly identical (names should not be case sensitive). The method will take a Baby type parameter and use the calling object (thus comparing these two objects via name and age); it should return Boolean - true or false as appropriate. Remember, if comparing Strings, you must use String comparison methods. 4. Test your Baby class by writing a client program which uses an array to store information about 4 babies. That is, each of the four elements of the array must store a Baby object. If you have an array for baby names and another array for baby ages, then you have missed the point of the exercise and therefore not met the requirement of this exercise. A Baby class object stores the required information about a Baby. So each Baby object will have its own relevant information, and thus each object must be stored in one element of the array.

For a Solid Oxide Fuel Cell stack that uses hydrogen as fuel and operates at 800°C (same as question 1 of Homework 9), if the inlet hydrogen flow rate is 20 mol/min, hydrogen conversion is 60%, and 60% of the produced energy can be converted into electrical energy, what would be the power output of the stack in kW.

That is, each of the four elements of the array must store a Baby object. If you have an array for baby names and another array for baby ages, then you have missed the point of the exercise and therefore not met the requirement of this exercise. A Baby class object stores the required information about a Baby. So each Baby object will have its own relevant information, and thus each object must be stored in one element of the array. The client program should: a. Enter details for each baby (name and age) and thus populate the Baby array b. Output the details of each baby from the array (name and age) c. Calculate and display the average age of all babies in the array d. Determine whether any two babies in the array are the same As the required information for these tasks is stored in the Baby array, you will need to use a loop to access each array element (and use the dot notation to access the appropriate set and get methods to assign/retrieve the information). For part d above, a nested loop is required. The given code is: public class Baby { private String name; private int age; public Baby() { } public Baby(String babyName, int babyAge) ( ) public String getName() { return name; } public int getAge()(....) public void setName (String babyName)(...) public setAge(int babyAge)(...) public boolean equals(Baby otherBaby)(...) (// compare name and age and return // true or false accordingly ) } public class BabyTest { public static void main(String[] argv) ( Baby[]babies = new baby[4]; //(a) for( int i = 0; i<babies.length; i++) (//prompt user for baby name and age. Create baby //instance and save the instance in the array ) //(b) for( int i = 0; i<babies.length; i++ ) (//print name and age of each instance in the array ) //(c) double totalAge = 0; for( int i = 0; i<babies.length; i++) (//Sum the age of each baby instance ) //Calculate and print the averagea age ... //(d) boolean sameBaby = false; for( int i = 0; i<babies.length; i++) ( //compare each baby instance with all other //instance using nested loop //use equals(...)method to compare ) if ( sameBaby == true) ... ) }
