PLS HELP For this activity, you can use the audio recorder on your cell phone or a digital camera to record the following sounds: • the sound of footsteps of someone walking towards you
• the sound of a person starting a car, rewing the engine, and driving away
• the sound of a phone ringing at home as you walk toward it the sound of somebody speaking to you as you walk toward that person
After you record these sounds from different sources, play them back and observe the differences in the recorded sound from each source. Write a note recounting your experience and observations for each of these recordings.
Answer:
So you put down what is recorded. Because every time you Play back the audio it sound's different. When you are doing the Exp. It's Called Sound waves My Friend
Explanation:
Answer:
I recorded the four types of sounds as mentioned in the question. When I played them back, they seemed to create a dramatic effect.
The footsteps sounded quite dramatic and added purpose to the activity. I recorded the sound of my sister's footsteps as she walked down the stairs in high heels and then as she walked past me. When I was recording the sound, the footsteps sounded normal. However, when I heard the recorded footsteps, the sound of the slow, approaching footsteps created a sense of mystery. Who was the person walking down the stairs? Why was the person hurrying past me? Did she achieve what she set out to do? In addition, I noticed perspective in a sound effect for the first time. It started softly and then became louder. As she moved past me and went away, it became softer again until it finally faded away.
The engine noise, and the sound of starting and driving the car, brought out the innate nature of the sound and emphasized that there is more to starting an engine than just moving the car. For instance, when the car engine started, it was clear that the driver was heading somewhere. The car's constant "vrooming" noise indicated that the driver was waiting to drive. However, the question is, "What's the rush?" The sound of the car driving away indicated that the driver finally drove away. I also noticed that the way the car drives away reveals the driver's state of mind. When the driver is in a rush and swerves and drives away at great speed, there will be drama. This is different from the peaceful, non-rushed driving style of a person going out for a drive with his or her family. The sound of people going to work will be different from the sound of people going on a holiday or going shopping on a weekend.
Walking toward a ringing phone added an element of surprise to the action. I placed the recorder near the phone and could hear myself walking toward it. When I heard the recorded sound, it sounded as though I was in no rush to pick up the ringing phone. It sounded just like any other regular action, not one filled with drama or mystery.
As I walked toward my friend while he spoke, his voice sounded louder and clearer. The effect was similar to zooming in on an image from a distance. This adds perspective to sounds and voices, and it adds depth to the visuals as well.

Write a static method that takes a String and returns an integer. Return the number of characters in the passed in, String parameter.
Answer:
Explanation:
The following code is written in the Java programming language. It is a function called howBig that takes in a String as a parameter and returns an int. The function grabs the string and then detects the size of the String (number of Characters it has) and then places that number into an Integer variable called wordSize. Then it returns the variable wordSize.
public static int howBig (String myWord) {
int wordSize = myWord.length();
return wordSize;
}
Following are the Program to the given question:
Program Explanation:
Defining a class "Main".Inside a class, a method "Length" is defined that takes string variable "s" as the parameter.Inside the method, a conditional statement is defined that checks length of the string value and prints its value.In the next step, the main method is declared that calls the length method, and print its return value.Program:
public class Main //defining a class Main
{
public static int Length(String s)//defining a method getLength that takes String parameters
{
if(s==null)//defining if block that check s parameter value equal to null
{
return 0;//return 0
}
else //defining else block
{
return s.length();//using return keyword that return length of String
}
}
public static void main(String[] args) //defining a main method
{
System.out.println(Length(null));//calling method and print its value
System.out.println(Length("abcd"));//calling method and print its value
}
}

Explanation:
C++ Write a program that initially asks a user to enter two positive integer numbers a and b. If either a or are zero or negative, the program terminates right away. Then, generate an array of 20 integer numbers, each randomly generated between a and b. If b happens to be greater than a, then the array must contain elements randomly generated between b and a. Display the whole array on the screen. After creating and displaying the array, the program shows:
[A]verage [S]um [F]ind Please choose an option: Then, if the user selects:
- A (lowercase or uppercase): the program computes and displays the average of all elements of the array
-A (lowercase or uppercase): the program computes and displays the average of all elements of the array
-F (lowercase or uppercase): the program asks the user to insert an integer number to be found in the array
If present, the program displays "Found in position number followed by the position of the first occurrence.
If not present, the program displays "Number not found in the array"

Answer:
I assume you want to set the opacity (0-100) depending on the mouse's coordinate on the screen. The variables indicating the mouse's coordinates are mouseX and mouseY.
To achieve this, you will need to divide the mouseX/mouseY (whichever you choose) by 4 to what's called "normalize" it. If your mouse was at 320 for example... Dividing it by four would give you 80, and this works because the bounds that the opacity can be set to is 0-100.
normalized = mouseX / 4
Circle(mouseX, mouseY, 50, fill='navy', opacity=normalized)
...or if you want to do it in one line...
Circle(mouseX, mouseY, 50, fill='navy', opacity=mouseX / 4)

When reading data from a URL it is good practice to use a try/except block to catch any errors that may arise. A. True B. False
Answer:
False
Explanation:
It is FALSE that When reading data from a URL it is good practice to use a try/except block to catch any errors that may arise.
This is because the "try/except" function is a python programming language function that is used in python to solve issues like race conditions, controlling errors in loops, file handling, database communication, network access, and many more.
The statement, "When reading data from a URL it is good practice to use a try/except block to catch any errors that may arise" is:
FalseAccording to the given question, we are asked to show if the given statement is true or false about the use of a try/except block to catch errors when getting data from a URL.
As a result of this, when reading data from a Universal Resource Locator, it is not good practice to make use of a try/except block to try and catch any errors that may occur because this is a function which is used to solve race conditions and to handle error loops.
Therefore, the correct answer is False.
