When programming in the MakeCode Arcade interface, why would you select
one of the buttons in the bottom right corner of the screen?

Answers

In the MakeCode Arcade interface, buttons in the bottom right corner of the screen are typically selected to change the display mode between code blocks and JavaScript.

How does a computer go through technical stages when booting up and navigating to the sample website? Answer the question using Wireshark screenshots.

Answers

When a computer is turned on, it goes through several technical stages before it can navigate to a sample website. The following are the basic steps involved in booting up a computer and accessing a website:

How to explain the information

Power On Self Test (POST): When a computer is turned on, it undergoes a Power On Self Test (POST) process, which checks the hardware components such as RAM, hard drive, CPU, and other peripherals to ensure they are functioning properly.

Basic Input/Output System (BIOS) startup: Once the POST process is complete, the BIOS program stored in a chip on the motherboard is loaded. The BIOS program initializes the hardware components and prepares the system for booting.

Boot Loader: After the BIOS startup is complete, the boot loader program is loaded. This program is responsible for loading the operating system into the computer's memory.

Operating System (OS) startup: Once the boot loader program has loaded the operating system, the OS startup process begins. During this process, the OS initializes the hardware, loads device drivers, and starts system services.

Web browser launch: After the OS startup is complete, the user can launch a web browser. The web browser program is loaded into the memory, and the user can navigate to a sample website.

DNS Lookup: When the user types in the website address, the computer performs a Domain Name System (DNS) lookup to translate the website name into an IP address.

HTTP Request: After the IP address is obtained, the web browser sends an HTTP request to the web server that hosts the website.

Website content delivery: Once the web server receives the HTTP request, it sends back the website content to the web browser, and the website is displayed on the user's screen.

These are the basic technical stages involved in booting up a computer and navigating to a sample website.

Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.045) / 12.

Ex: If the input is 200000 210000, the output is:

This house is $200000. The change is $-10000 since last month.
The estimated monthly mortgage is $750.0.

Answers

Answer:

here is the answer

Explanation:

current_price = int(input("Enter the current price: "))

last_months_price = int(input("Enter the last month's price: "))

print("Current price is: " + str(current_price) + ", Last month's price was: " + str(last_months_price))

print("The change since last month is: " + str(current_price - last_months_price))

print("The estimated monthly mortgage is: " + str(current_price * 0.051))

Get the inputs for the current price and last month's price

Print the prices

Calculate and print the change, current_price - last_months_price, since last month

Calculate, using given formula, and print the estimated monthly mortgage

Enter("Enter the current price: ") current price = int, enter("Enter the last month's price: ") last months price = int.

What is Program?

The price last month was: " + str(last months price) and the current price is: " + str(current price) + ".

print("The difference from the previous month is: " + str(current price - last months price)). print("The approximate mortgage payment is: " + str(current price * 0.051))

Obtain the inputs for the price today and the price last month.

Therefore, Enter("Enter the current price: ") current price = int, enter("Enter the last month's price: ") last months price = int.

Put the code in a function that takes two parameters-- the text and the letter to be searched for. Your header will look like def count_letters(p, let) This function will return the number of occurrences of the letter.
Use a main() function to get the phrase and the letter from the user and pass them to the count_letters(p,let) function. Store the returned letter count in a variable. Print "there are x occurrences of y in thephrase" in this function.

What will be the different if the syringes and tube are filled with air instead of water?Explain your answer

Answers

Answer:

If the syringes and tubes are filled with air instead of water, the difference would be mainly due to the difference in the properties of air and water. Air is a compressible gas, while water is an incompressible liquid. This would result in a different behavior of the fluid when being pushed through the system.

When the syringe plunger is pushed to force air through the tube, the air molecules will begin to compress, decreasing the distance between them. This will cause an increase in pressure within the tube that can be measured using the pressure gauge. However, this pressure will not remain constant as the air continues to compress, making the measured pressure unreliable.

On the other hand, when the syringe plunger is pushed to force water through the tube, the water molecules will not compress. Therefore, the increase in pressure within the tube will be directly proportional to the force applied to the syringe plunger, resulting in an accurate measurement of pressure.

In summary, if the syringes and tube are filled with air instead of water, the difference would be that the measured pressure would not be reliable due to the compressibility of air.
