An activity to prove that sounds can travel in a liquid medium in long time is:
Use a tub that is filled with water, also take a bell in one of your hand and then one can dip it into the water. Note that you need to Keep one of your ears close to the surface of water and do not let the water go into the ear. Then ring the bell inside the tub water. You will be able to hear the sound very clearly. This tells that sound can travel via liquids.
How do sounds travel in liquids?Sound waves is known to be one that tends to travel a lot faster in denser forms or kinds of substances due to the fact that neighboring particles will be able to bump into each other.

Answer:
SELECT product_name, SUM(DISTINCT quantity) AS total_quantity
RANK() OVER (PARTITION BY total_quantity ORDER BY product_name) AS rank,
DENSE_RANK () OVER (ORDER BY quantity DESC) AS dense_rank
FROM Order_items
JOIN products ON Order_items.product_id = products.product_id

Review how to write a for loop by choosing the output of this short program.
for counter in range(3):
print(counter * 2)
Please explain it to me, I’m not learning Bc I don’t have a teacher.
Answer:
The output is:
0
2
4
Explanation:
First of all, the print statement must be indented with a tab, otherwise it is not part of the for loop.
The range(3) creates an array with values 0,1,2. The variable 'counter' gets those values one after another, and the print statement outputs this value doubled, hence the 0, 2 and 4 output.
Write a method called isMagicSquare that accepts a two-dimensional array of integers as a parameter and returns true if it is a magic square. A square matrix is a magic square if it is square in shape (same number of rows as columns, and every row the same length), and all of its row, column, and diagonal sums are equal. For example, [[2, 7, 6], [9, 5, 1], [4, 3, 8]] is a magic square because all eight of the sums are exactly 15.
Answer:
def isMagicSquare(myArray: list) -> bool :
row_num = len(myArray)
cols_num = [len(x) for x in myArray]
count =0
for x in cols_num:
if row_num == x:
count += 1
if count == len(cols_num):
return True
else:
return False
print(isMagicSquare([[1,2,3,1],[3,34,2,4],[43,5,7,5],[2,3,4,5]]))
Explanation:
In object-oriented programming, a method is a function defined in a class. Methods are actions that can be taken or executed in a class or to a class object.
The "isMagicSquare" is a python function or method in a class that returns true if a two array or list is a perfect square (same column and row length).

Create a php user defined function called MinMax. The function accepts two numbers as arguments and it returns the string: "The minimum number is x and the maximum number is y" where x and y are the minimum and the maximum numbers respectively. For example, if the numbers 20 and 4 are passed to the function MinMax, it should return the string:
Answer:
<?php
function MinMax($x,$y) {
if($x > $y){
echo("The minimum is ".$y." and the maximum number is ".$x);
}
else{
echo("The minimum is ".$x." and the maximum number is ".$y);
}
}
MinMax(20,4);
?>
Explanation:
<?php
This defines the user function with two parameters x and y
function MinMax($x,$y) {
This checks if parameter x is greater than parameter y
if($x > $y){
If yes, it prints x as the maximum and y as the minimum
echo("The minimum is ".$y." and the maximum number is ".$x);
}
If otherwised
else{
If yes, it prints y as the maximum and x as the minimum
echo("The minimum is ".$x." and the maximum number is ".$y);
}
}
This calls the function
MinMax(20,4);

PLS HELP ASAP- Select the correct text in the passage.
Which concept explained in the paragraph below means that data always remains consistent?
Specific programs have some tasks that a computer must perform in parallel with others. These tasks (such as the performance of the same set of operations on different data sets) often work in parallel clusters. In such cases, a separate thread of execution handles each separate task. You can think of a thread as a sequence of instructions that computers can manage independently.
It is possible for different threads to access the same data elements and change their values, and this can lead to an inconsistent state of information. For instance, if multiple programs access a shared variable x and change its value, the variable will not contain the correct value at the end of the programs. We can prevent such inconsistencies by using locks. A thread puts a lock on shared data, and releases this lock only after completing its operations.

The attenuation of a signal is -10 dB. What is the final signal power if it was originally
5 W?
Answer:
P₂ = 0.5 W
Explanation:
It is given that,
The attenuation of a signal is -10 dB.
We need to find the final signal power if it was originally 5 W.
Using attenuation for signal :
[tex]dB=10\text{log}_{10}(\dfrac{P_2}{P_1})[/tex]
Put dB = -10, P₁ = 5 W
Put all the values,
[tex]-10=10\text{log}_{10}(\dfrac{P_2}{5})\\\\-1=\text{log}_{10}(\dfrac{P_2}{5})\\\\0.1=\dfrac{P_2}{5}\\\\P_2=5\times 0.1\\\\P_2=0.5\ W[/tex]
So, the final signal power is 0.5 W.
The final signal power if it was originally 5W is; 0.5 W
Signal PowerWe are given;
Attenuation signal; dB = -10 dBOriginal signal power; P1 = 5 WFormula for attenuation signal is;
dB = 10log_10_ (P2/P1)
Where P2 is final signal power
Thus;
-10 = 10log_10_(P2/5)
-10/-10 = log_10_(P2/5)
-1 = log_10_(P2/5)
0.1 = P2/5
P2 = 0.1 × 5
P2 = 0.5 W

Please help this computer science question(Pseudocode and Trace table)
Answer:
can u explain more specific plz
Explanation:
Add the beginning comments at the top of the program.
In the first part of your program, create a for loop that runs three times:
Inside the for loop, prompt the user for an integer
Prompt the user for another integer
Call the function compare (you are going to create this function next)
Pass the variables that you used for the integer inputs from above
Create a function called compare (remember the function definition should go at the top of the program) and use two variables in the parameters of the function:
Inside of the function, create an if / elif / else structure that compares the two values passed into the function
If one value is less than the other, output that to the user (Ex: 2 is less than 4)
Elif the other value is less than the other output something similar (Ex: 4 is less than 9)
Else, output that they are equal to each other
That is it for the first part of the program.
Next, create an empty list called names.
Create a loop that runs 6 times:
Inside of the for loop, prompt the user for a name
Append the name to the list
Outside of the for loop, prompt the user for how many people they would like to vote off the island.
Call the function eliminate and pass the variable you used from step 7 to it.
Also, this function will return a value, so store this back function call back to a new variable.
Create a function called eliminate and create a variable to use as the parameter:
Inside the function, randomly shuffle (use the shuffle() method) all the values in the list (you will need to import random at the top of the program)
Then using a for loop, loop it as many times as the value that was passed to the function:
Inside the for loop, remove one name from the list (use the pop() method)
Outside the for loop, but still inside the function, return the list of remaining people
Underneath where you left off in step 8, print the remaining people that are left: those that did not get voted off the island.
