The neutralization of 50.0 mL of 1.00 M hydrochloric acid with 50.0 mL of 1.00 M sodium hydroxide causes a 6.7°C increase in temperature. Predict how the following changes to the experimental protocol would affect the value of the change in temperature.

The temperature change depends on the moles of water produced (moles of reaction) and the mass of the solution. Assume that the density of each solution is 1.0 g/mL.
a. using 100.0 mL of 1.00 M hydrochloric acid and 100.0 mL of 1.00 M sodium hydroxide
b. using 50.0 mL of 2.00 M hydrochloric acid and 50.0 mL of 2.00 M sodium hydroxide
c. using 25.0 mL of 1.00 M hydrochloric acid and 75.0 mL of 1.00 M sodium hydroxide
d. using 25.0 mL of 1.00 M sulfuric acid and 75.0 mL of 1.00 M sodium hydroxide (Be careful. Think about the value of n!)

According to researchers at Stanford Medical School (as cited in Medical Self Care), the ideal weight for a woman is found by multiplying her height in inches by 3.5 and subtracting 108. The ideal weight for a man is found by multiplying his height in inches by 4 and subtracting 128. Using PHP and HTML 5, design and build a web page that calculates the ideal weight given the person’s gender and height. The user selects the gender from a drop down list and enters the height in a text box. Your PHP script should read all the input and calculate and display the ideal weight.

The following java files are created from this:

• BankAccount.java
• CheckingAccount.java
• SavingsAccount.java
• TransactionDriver.java

Objective: To learn about inheritance and understand how to inherit and override superclass methods and to be able to invoke superclass constructors

In this assignment we will simulate a bank transactions that offers the customer the following types:

1. Checking account that does not provide interest, but it does provide a limited free transactions per month. Additional checking account transactions are charged a small fee.
2. Savings account that earns interest on a monthly basis.

Program Specification and implementation

Create a superclass BankAccount and two subclasses CheckingAccount and SavingsAccount. All the bank accounts should support getBalance, deposit and withdraw methods. Follow the below detailed specifications for each class.

BankAccount:

-         Implement instance field balance

-         Constructor creates an account with 0 balance.

-         Constructor to create an account with an initial balance

-         deposit method that takes in amount to be deposited

-         withdraw method that takes amount to withdraw

-         getBalance method to return the current balance in the account.

-         transferMoney method that transfers money from this bank account to other bank account. This method takes two arguments (BankAccount otherAccount, double amount)

-         display method that displays the account balance.

CheckingAccount:

-        Constant instance fields for ALLOWED_TRANS and TRANS_FEE. Allow for 2 free transactions and $3 for additional transaction.

-         instance field transactionCount (specific and new to CheckingAccount).

-         Constructor to create zero balance account.

-         Constructor to create an account with an initial balance

-         override deposit and withdraw methods in order to increment the transaction count.

-         chargeFees that charges transaction fee if any to the account at the end of the period.

SavingsAccount:

-         Instance field interestRate that holds the interest rate for period.

-         Constructor that sets interest rate.

-         Constructor that sets rate and initial balance.

-         addCompoundInterest method that adds the interest for the current period to the account balance. Deposit the interest to the account. Use this formula to calculate interest = balance * interestRate / 100.0.

TransactionsDriver:

-         Instantiate a savings account name it dadsSavings with interestRate 0.3%

-         Instantiate a checking account and name it kidsChecking.

-         Deposit 10000 into dadsSavings account.

-        Transfer 3000 to kidsChecking

-        Withdraw 200 from kidsChecking

-         Withdraw 400 from kidsChecking

-         Withdraw 300 from kidsChecking

-        Withdraw 500 from kidsChecking

-         Withdraw 400 from kidsChecking

-         Invoke end of period interest for the savings account

-        Invoke end of period transactions fees for the checking account

-        Display the final balance for dadsSavings account

-         Display the final balance for kidsChecking account

-         End of program

Sample Output:

At the end of these transactions the bank accounts should have the below balances

End of the period account balances

Dad's savings. Account balance: 7021.0

kid's checking. Account balance: 1188.0

Also, draw the inheritance UML diagram for the three bank accounts classes.

The mode of a set of numbers is the number that occurs most frequently in the set. For example, the set {4, 3, 6, 4, 3, 4, 1} has mode 4.

(a) (10%) Give an efficient, in-place algorithm to compute the mode of a set. Give the running time of your algorithm as a function of number of elements in the set, n. Show all work!

(b) (10%) Now suppose we know that there exists an element that occurs at least (n/2) + 1 times in the set, where n is the number of elements in the set. Give an O(n) algorithm to find the mode of this set.

9 starch agar plates have been inoculated with different bacteria in order to see if each bacterial species has amylase to hydrolyze the starch. After incubation, Gram's iodine must be added to see if the results were positive or negative. Before applying the Gram's iodine, the plates are incubated for 48 hours.

What should you expect to happen if you applied the Gram's iodine after 2 hours of incubation instead of the 48 hours and why?

A) Calculate the kinetic energy of a proton (1.67×10−27kg) traveling 8.30×10⁷ m/s .

B) Calculate the momentum of a proton (1.67×10−27kg) traveling 8.30×10⁷ m/s .

C) By what percentages would your calculations have been in error if you had used classical formulas?

Review Exercise 3-1 on page 115 of the text. Compute the company's predetermined overhead rate and explain the four-step process to compute a predetermined overhead rate. How would this rate be effected if the direct labor hours increased to 25,000? How would the rate be effected if the overhead were to increase to $150,000. Give examples of some of the challenges a manager may have in completing this computation.

Harris Fabrics computes its predetermined overhead rate annually on the basis of direct labor hours. At the beginning of the year, it estimated that 20,000 direct labor-hours would be required for the period’s estimated level of production. The company also estimated $94,000 of fixed manufacturing overhead expenses for the coming period and variable manufacturing overhead of $2.00 per direct labor hour. Harris’s actual manufacturing overhead for the year was $123,900 and its actual total direct labor was 21,000 hours.

Required:

Compute the company’s predetermined overhead rate for the year.

READ the scenario below here first What stands out to you the most? You are looking for the THREE (3) main issues that you will base your appellate brief on: how did the lower (trial) court err and/or what did the lower (trial) court do wrong? It is these three (3) issues or errors that we are pointing out to the appellate court. We are asking the appellate court to reverse the lower (trial) court’s ruling because of these errors and send it back for re-trial. You will have to start a bit of research here to fully understand what the THREE (3) issues are. Please use Google or Lexis to begin your legal research on educating yourself on this topic. Look for cases on these topics.

Your Case:  “Morty’s Moral Matter”

The situation described below is hypothetical.

Our client, Morty Smith, is a 17-year old high school senior who attends Harry Herpson High School ("Herpson High"). Morty refers to himself as a “Practicing Pastafarian” and a devout member of the Church of the Flying Spaghetti Monster.

Herpson High is operated by Meseeks Unified School District (the "School District"), a school district that operates elementary, middle, and secondary schools in Florida.  In planning its graduation ceremony and program, Herpson High notified parents of the graduating seniors that student-led and student-initiated nondenominational prayers would be offered at the graduation.  Attendance at the graduation would be voluntary.  School officials at Herpson High would review any prayers that were submitted by students before they were offered at the ceremony. Morty submitted to the school a “prayer” that he wished to read at graduation:

“Our pasta, who art in a colander, draining be your noodles. Thy noodle come, Thy sauce be yum, on top some grated Parmesan. Give us this day our garlic bread, and forgive us our trespasses, as we forgive those who trample on our lawns.”

School officials denied Morty’s request to read his prayer with no reason given for the rejection.  No other student received such a rejection, and the school allowed all other prayers submitted by student’s to be read at graduation.

Morty Smith sued the School District on the basis that the school violated his Constitutional rights. Among other issues, he specifically claimed that the prayers allowed at graduation violated his First Amendment right to free speech and the First Amendment's prohibition against laws relating to establishment of religion.  On a Motion for Summary Judgment, the Middle District of Florida Trial Court ruled against Mr. Smith on the School District's Motion for Summary Judgment, holding that students are not afforded the same protections as adults under the Constitution as per Freedom of Speech. Furthermore, the Court ruled that the student-led and student-initiated nondenominational prayers could not violate the US Constitution.

          Morty Smith has ample funds (backed by his grandfather, Rick) and wants to appeal to the United States Court of Appeals for the Eleventh Circuit.
