Answer two JAVA OOP questions. Question 65 out of 10 pointsWrite a Java method that validates a given password and returns a boolean value (true or false). To be true, the password must be at least10 characters long and have at least two numbers. Question 56 out of 10 pointsUsing course terminology, explain the difference between a static method and an instance method. In your answer be sure to specify whichtype of variables each method can access and if the class needs to be instantiated to access that type of method.

The first question requires us to write a Java method that validates a password based on certain…

(Physics) Write an assignment statement to calculate the elapsed time, in minutes, it takes to make a trip. The formula for computing elapsed time is elapsed time = total distance / average speed. Assume the distance is in miles and the average speed is in miles per hour (mph).

When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)
(Numerical) Write an assignment statement to calculate the nth term in an arithmetic sequence. This is the formula for calculating the value, v, of the nth term: v=a+(n1)d a is the first number in the sequence. d is the difference between any two numbers in the sequence.

Write an assignment statement to calculate the force, F.
Pig Latin is a nonsense language. To create a word in pig Latin, you remove the first letter and then add the first letter and ay at the end of the word. For example, dog becomes ogday and cat becomes atcay. Write a program named PigLatin that allows the user to enter a word and displays the pig Latin version.
(Statistics) This is the formula for the standard normal deviate, z, used in statistical applications: z=(X)/ X is a single value. refers to an average value. refers to a standard deviation. Using this formula, you need to write a program that calculates and displays the value of the standard normal deviate when X=85.3,=80,and=4. a. For this programming problem, how many outputs are required? b. How many inputs does this problem have? c. Determine a formula for converting input items into output items. d. Test the formula written for Exercise 7c, using the data given in the problem.
