I am tasked with creating a Java application that used 2 synchronized threads to calculate monthly interest and update the account balance

This is the parameters for reference to the code. Create a class AccountSavings. The class has two instance variables: a double variable to keep annual interest rate and a double variable to keep savings balance. The annual interest rate is 5.3 and savings balance is $100.
• Create a method to calculate monthly interest. • Create a method to run two threads. Use anonymous classes to create these threads. The first thread calls the monthly interest calculation method 12 times, and then displays the savings balance (the balance in 12th month). After that, this thread sleeps 5 seconds. The second thread calls the monthly interest calculation method 12 times, and then displays the savings balance (the balance in 12th month). Before the main thread ends, these two threads must be completed. • Add your main method into the same class and test your threads. After these two threads are executed, the savings balance must remain same

I am getting an error when calling monthlyInterest method inside my runThread method. non-static method monthlyInterest() cannot be referenced from a static context and I cant seem to figure out how to fix the issue.


import static java.lang.Thread.sleep;

class AccountSavings {

    double annualInterest=5.3;
    double savings=100.00;
  
  

    public void monthlyInterest(){
    double monthlyRate;
    monthlyRate = annualInterest/12;
    double balance = 0;
    balance+=savings*monthlyRate;
    }
  
    public synchronized static void runThread(){
  
        Thread t1;
        t1 = new Thread(){
            AccountSavings accountSavings= new AccountSavings();
            @Override
            public void run(){
                for(int i=1;i<13;i++){
                    System.out.println("Balance after " + i + "month: " + monthlyInterest());
                }
                try{sleep(5000);}
                catch(InterruptedException e){e.printStackTrace();}
            }
        };
    Thread t2= new Thread(){
  
    AccountSavings accountSavings=new AccountSavings();
    @Override
    public void run(){
  
        for(int i=1;i<13;i++){
        System.out.println("Balance after " + i + " month: " + monthlyInterest(balance));
        }
        try{sleep(5000);}
        catch(InterruptedException e){e.printStackTrace();}  
    }
    };
    t1.start();
    t2.start();
  
    }

    public static void main(String[] args){
  
        runThread();
  
    }

}

Given the following thermochemical equations:

X2+3Y2 equals 2XY3 and Delta H =-340 kJ

X2+2 Z2 equals 2XZ2 and Delta H = -170 kJ

2Y2 + Z2 equals 2Y2Z and Delta H=-260kJ

Calculate the change in enthalpy for the following reaction

Chamberlain Enterprises Inc. reported the following receivables in its December 31, 2021, year-end balance sheet:

Current assets:
Accounts receivable, net of $35,000 in allowance for
uncollectible accounts
$ 273,000
Interest receivable 10,100
Notes receivable 370,000


Additional Information:

  1. The notes receivable account consists of two notes, a $100,000 note and a $270,000 note. The $100,000 note is dated October 31, 2021, with principal and interest payable on October 31, 2022. The $270,000 note is dated June 30, 2021, with principal and 6% interest payable on June 30, 2022.
  2. During 2022, sales revenue totaled $1,450,000, $1,335,000 cash was collected from customers, and $33,000 in accounts receivable were written off. All sales are made on a credit basis. Bad debt expense is recorded at year-end by adjusting the allowance account to an amount equal to 10% of year-end accounts receivable.
  3. On March 31, 2022, the $270,000 note receivable was discounted at the Bank of Commerce. The bank's discount rate is 10%. Chamberlain accounts for the discounting as a sale.


Required:
In addition to sales revenue, what revenue and expense amounts related to receivables will appear in Chamberlain’s 2022 income statement?
What amounts will appear in the 2022 year-end balance sheet for accounts receivable and Calculate the receivables turnover ratio for 2022.

On a frictionless surface, a block of mass m1 and velocity v1 = vi is moving to the right when it collides with a spring, of spring constant k, attached to the left side of a stationary block of mass m2. Both blocks are free to slide on the surface.

(a) Argue either from physical principles or with equations that the velocities of the two blocks are the same when the spring is at its maximum compression.

(b) What is the maximum compression of the spring, xmax?
(c) In terms of m1,m2, and v, what are the final velocities of the two blocks after

they finish interacting?

In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 52.0 km due north. A detector is placed 107 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector.

(a) When properly aligned, what angle should the normal to the surface of the mirror make with due south?

(b) Suppose the mirror is misaligned, so that the actual angle between the normal to the surface and due south is too large by 0.005
