Here's a Java program that takes an initial key frequency and outputs that frequency and the next 4 higher key frequencies:

import java.util.Scanner;

public class PianoKeys {

   public static void main(String[] args) {

       Scanner sc = new Scanner(System.in);

       double f0 = sc.nextDouble();

       double r = Math.pow(2.0, 1.0/12.0);

       System.out.printf("%.2f", f0); // output the initial frequency

       for (int n = 1; n <= 4; n++) {

           double fn = f0 * Math.pow(r, n);

           System.out.printf(" %.2f", fn); // output the next higher frequency

       }

       System.out.println(); // end the line

   }

}

Explanation of Java program:

The program reads the initial frequency f0 from the user, computes the ratio r, and then uses a loop to output the initial frequency and the next 4 higher frequencies. Each frequency is computed as f0 * r^n, where n is the distance from the initial key, and then output with two digits after the decimal point using "System.out.println()". Finally, the program ends the line with System.out.println().

The number of revolution that the CD makes as it spins to a stop depends on the initial speed of the CD and the rate at which it decelerates.

the initial angular velocity is 500 revolutions per minute (rpm) and the angular acceleration is -20.1 rad/s2.

We can convert 500 rpm to radians per second by multiplying by 2π/60, which gives 52.4 rad/s.

Then we can use the formula for angular displacement, which is Δθ = ω0t + (1/2)αt^2, where ω0 is the initial angular velocity, α is the angular acceleration, and t is the time.

We know that the CD stops when its final angular velocity is zero, so we can use another formula, ω = ω0 + αt, to find the time it takes to stop.

Solving for t gives t = -ω0/α = -52.4/-20.1 = 2.61 s. Plugging this into the formula for angular displacement gives Δθ = (52.4)(2.61) + (1/2)(-20.1)(2.61)^2 = 68.3 rad.

To convert this to revolutions, we divide by 2π, which gives 10.9 revolutions. Therefore, the CD makes about 10.9 revolutions as it spins to a stop.

The "pe = pm" assignment, the pointer variable "pe" of type Employee* now points to the same object that "pm" points to, an instance of the Manager class.

This is allowed because of the "is-a" relationship between the Employee and Manager classes.

"pe" is still declared as a pointer to the base class, Employee, it can only access the members and functions of the Employee class.

If you want to access the Manager-specific members or functions of the object, you would need to perform a type cast from Employee* to Manager*.

It's also important to note that since "pe" was originally allocated as an Employee object, and "pm" was allocated as a Manager object, assigning "pe = pm" would cause a memory leak, since the original pointer to the Employee object is lost and cannot be deallocated.

The channel utilization of a pipelined protocol with an arbitrarily high level of pipelining for this channel is 90.9%.

The formula for calculating the channel utilization of a pipelined protocol is given as:

U = N * L / (RTT + L / R)

where:

N = the number of packets in the pipeline

L = the packet length

RTT = the round-trip propagation delay

R = the channel transmission rate

Let's assume an arbitrarily high level of pipelining, then we set

N = 1000

Substitute the given values into the equation then we have:

U = 1000 * 10,000 / (10 * 10⁻³ + 10,000 / 10⁻⁶)

       thousands = num // 1000

       hundreds = (num // 100) % 10

       tens = (num // 10) % 10

       ones = num % 10

       # Check if the thousands place digit is three times the tens place digit

           if thousands + hundreds + tens + ones == 27:

               # Print the address

               print("The Riddler plans to strike at", num)

Explanation:

This program uses a for loop to iterate through all odd four-digit numbers from 1001 to 9999 (inclusive). For each number, it checks if all four digits are different using the set function to remove duplicates from the string representation of the number. If all four digits are different, it extracts the thousands, hundreds, tens, and ones place digits using integer division and modulo operations. It then checks if the thousands place digit is three times the tens place digit and if the sum of the digits is 27. If both conditions are true, the program prints the address where the Riddler plans to strike.

Yes, the order in which you set your multiple parameters in a function does matter. The order determines which argument is assigned to each parameter when the function is called

When you call the function later, the arguments you pass will be assigned to the corresponding parameters based on their position.

For example, if your function definition is:

`def example_function(param1, param2, param3):` and you call the function like this: `example_function(value1, value2, value3)` `value1` will be assigned to `param1`, `value2` to `param2`, and `value3` to `param3`.

If you change the order of parameters in the definition, it could lead to incorrect assignments and unexpected behavior. However, you can use named arguments when calling the function to avoid issues with order:

`example_function(param1=value1, param3=value3, param2=value2)`

This allows you to specify which values correspond to which parameters, regardless of their order in the definition.

The correct answer is d. {{2, 1, 1, 1}, {3, 2, 1, 1}, {3, 3, 2, 1}}. The code segment initializes a 2D array called mat with 3 rows and 4 columns, and then fills each element of the array based on the row and column index.

If the row index is less than the column index, the value of that element is 1. If the row and column indices are the same, the value is 2. Otherwise, the value is 3.

So, in the first row of the array, the first element has the value 2, the second element has the value 1, and the third and fourth elements also have the value 1.

In the second row, the first element has the value 3, the second element has the value 2, the third element has the value 1, and the fourth element also has the value 1.

In the third row, the first element has the value 3, the second element has the value 3, the third element has the value 2, and the fourth element has the value 1.

 The code to compute the sum of perfect squares less than `h`  is written  in Python:

h = 100 # Replace 100 with the desired value of h
sum = 0
i = 1

while i**2 < h:
 sum += i**2
 i += 1

print(sum)

Explanation:
- We start by setting the value of h to 100 (you can replace this with any desired value).
- We then initialize the variable "sum" to 0, and "i" to 1 (the first perfect square).
- Using a while loop, we keep adding the value of i^2 to "sum" as long as i^2 is less than h.
- After each iteration, we increment the value of I by 1.
- Once i^2 is greater than or equal to h, we exit the loop and print the value of "sum".
. Here's a step-by-step explanation using Python:

1. Initialize the sum to 0.
2. Loop through numbers starting from 1.
3. Check if the square of the current number is less than `h`.
4. If it is, add the square to the sum.
5. Continue looping until the square is greater than or equal to `h`.

Here's the code:

```python
def sum_of_perfect_squares(h):
   total = 0
   current_number = 1

   while True:
       square = current_number ** 2

       if square < h:
           total += square
           current_number += 1
       else:
