To calculate the number of revolutions that the CD makes as it spins to a stop, we need to know the initial angular velocity of the CD, the angular acceleration, and the time it takes for the CD to come to a stop.
What is the revolution about?It's also important to mention that, assuming the CD is slowing down with a constant angular acceleration, it's possible to use the kinematic equations of motion to find the final angular velocity and the angular displacement.
As we don't have those information, I can't give you an accurate answer. However, it is worth mentioning that the number of revolutions of a CD are about 200-600 revolutions per minute (RPM) depending on the CD player.

Define a function named SortVector that takes a vector of integers as a parameter. Function SortVector() modifies the vector parameter by sorting the elements in descending order (highest to lowest). Then write a main program that reads a list of integers from input, stores the integers in a vector, calls SortVector(), and outputs the sorted vector. The first input integer indicates how many numbers are in the list.
Ex: If the input is:
5 10 4 39 12 2
the output is:
39,12,10,4,2,
For coding simplicity, follow every output value by a comma, including the last one.
Your program must define and call the following function:

the resident of new york can be considered a population when developing some hypothesis test? True or false
The given statement "The residents of New York can be considered a population when developing some hypothesis tests." is true statement.
Why is the hypothesis test true?In statistics, a population refers to the entire group of individuals or objects that we are interested in studying. For example, if an insurance company wants to know the average car insurance premium of the residents of New York, the population would be all the residents of New York. Then, a sample of the population is taken and the statistics are gathered from the sample to make inferences about the whole population.
It's important to note that the sample should be randomly selected from the population to ensure that the sample is representative of the population, and that the sample size should be large enough to make accurate inferences about the population.
Therefore, the residents of New York can be considered a population when developing some hypothesis test if the sample is randomly selected and the sample size is large enough.

Space Battle JS Game
All day today, you will be using your knowledge of OOP, loops, and functions to build a rudimentary space battle game. The game will be programmed for, and played in the Chrome console. You will need to use pop-up prompts to get user input
SPECIFICATIONS
Build a game of battling alien spaceships using Javascript.
Earth has been attacked by a horde of aliens! You are the captain of the USS Assembly, on a mission to destroy every last alien ship. Battle the aliens as you try to destroy them with your lasers. There are six alien ships. The aliens' weakness is that they are too logical and attack one at a time: they will wait to see the outcome of a battle before deploying another alien ship. Your strength is that you have the initiative and get to attack first. However, you do not have targeting lasers and can only attack the aliens in order. After you have destroyed a ship, you have the option to make a hasty retreat.
A game round would look like this:
You attack the first alien ship
If the ship survives, it attacks you
If you survive, you attack the ship again
If it survives, it attacks you again
Etc.
If you destroy the ship, you have the option to attack the next ship or to retreat
If you retreat, the game is over, perhaps leaving the game open for further developments or options.
You win the game if you destroy all of the aliens.
You lose the game if you are destroyed.
Ship Properties
hull is the same as hitpoints. If hull reaches 0 or less, the ship is destroyed.
firepower is the amount of damage done to the hull of the target with a successful hit.
accuracy is the chance between 0 and 1 that the ship will hit its target.
Every time the ship will attack, calculate the chance that the damage will hit the opposing ship using Math.random()
If the ship's accuracy is 0.8 - then if the number generated from Math.random() is less than or equal to 0.8 then the attack will be successful. If the value is greater than 0.8 then the attack has missed.
Adjust the accuracy based on the specs for each ship
Your spaceship, the USS Assembly should have the following properties:
hull - 20
firepower - 5
accuracy - .7
The alien ships should each have the following ranged properties determined randomly:
hull - between 3 and 6
firepower - between 2 and 4
accuracy - between .6 and .8
Of course, you can use JavaScript to create a space battle using object-oriented programming, loops, and functions to get user feedback using popups. The code is shown below.
Describe JavaScript?
JavaScript is a programming language used primarily for creating dynamic, interactive web pages. It's a client-side scripting language, which means the code is executed by the web browser on the user's machine, not the server. JavaScript is commonly used in conjunction with HTML and CSS to create web pages that respond to user input, update them in real time, and display interactive content such as movies, animations, and games.

Select the correct answer from each drop-down menu. Identify the network you will use in the scenario. You are working from home, and you need remote access to your company's resources, located in a different city. You will use a because it Reset Next
Note that where you are working from home, and you need remote access to your company's resources, located in a different city, you will use VPN (Virtual Private Network) because it securely connects you to your company's network over the internet, allowing you to access company resources as if you were physically present in the office.
What is a Virtual Private Network?A virtual private network (VPN) is a method that allows a secure connection to be established between a cpu and a computer network, or between two networks, via an unsecured communication channel such as the public Internet.
VPNs encrypt your internet traffic and conceal your identity online. This makes it more difficult for third parties to follow your internet activities and steal information.

She asks: Which function would enable you to eliminate those extra spaces? you respond: to eliminate extra spaces for consistency, use the TRIM function.TrueFalse
It's True. The TRIM function can be used to eliminate extra spaces from a string of text.
TRIM function removes any leading or trailing spaces, as well as any multiple spaces between words, and replaces them with a single space. This can be useful for ensuring consistency in the formatting of text, as well as for cleaning up data before further processing. The TRIM function can be used in a variety of programming languages and platforms, such as SQL, Excel, and Python. The benefit of TRIM when text is used in formulas or data validation because spaces in front of or after the text are significant. TRIM removes all spaces in a text string, leaving just a single space between words.

In the Toy class below, the raisePrice method is intended to increase the value of the instance variable price by the value of the parameter surcharge. The method does not work as intended. public class Toy { private String name; private double price; public Toy(String n, double p) { name = n; price = p; } public void raisePrice(double surcharge) // Line 12 { return price + surcharge; // Line 14 } Which of the following changes should be made so that the class definition compiles without error and the method raisePrice works as intended? A. Replace line 14 with surcharge += price;. B. Replace line 14 with price += surcharge;. C. Replace line 14 with return price += surcharge;. D. Replace line 12 with public raisePrice (double surcharge). E. Replace line 12 with public double raisePrice (double surcharge).
The class definition compiles without error and the method raisePrice works as intended if we replace line 14 with price += surcharge
The method raisePrice() is missing a statement that assigns the new value of price after the surcharge is added. Therefore, the statement price += surcharge; will add the value of surcharge to the current value of price, and assigns it to price, effectively raising the price.
The other options will not work because:
A. surcharge += price; will add the current value of price to surcharge, but it will not affect the value of price.C. return price += surcharge; will add surcharge to price, but also it will return the new value of price, which is not the purpose of the method.D. public raisePrice (double surcharge) is missing the return type of the method, it should be public void raisePrice (double surcharge)E. public double raisePrice (double surcharge) is missing the return statement, so it will not return the new value of price.Learn more about return type of the method here:

in order to call a function within a source file (.cpp file), that function must be defined within the same source file.
On a Linux computer, use "g++ main. cpp &&./a. out" to run the cpp program.
Yes, we may run the main() method from within the main() function. Recursion is the process of executing a function by the function itself.
Recursion makes many calls to the function from within the function. The recursive condition invokes the function repeatedly until the base case is fulfilled. The base case is contained within the function, and when the condition of the base case is met, the execution is terminated.
For example, the function "find your way home" can be defined as: If you are at home, stop going. Take one step closer to home. "find your way home".
Initially, the sum() method is invoked from the main() function with number as an argument. Assume that the initial value of n within sum() is 3. 2 is provided to the sum() function on the following function call. This technique is repeated until n equals 0.

Why didn’t we have to typecast name as a str data type in the print statement?
The reason that one does not have to typecast name as a str data type in the print statement is given below
In Python, variables do not have a fixed data type. The data type of a variable is determined by the value it holds. When you assign a value to a variable, Python automatically determines the data type of the value and assigns that data type to the variable.What is the print statement?In the case of the variable "name", its data type is determined by the value that is assigned to it, which is a string. When you pass the variable "name" to the print() function, Python knows that it is a string data type and is able to print it without any issues.
So, we didn't have to typecast "name" as a string data type in the print statement because Python automatically infers the data type of the variable based on its value.
