Answer:
Explanation:
The following code is written in Python and is a function that loops three times asking for the last name and first name. Then it uses this information to create a username. Finally, each of the names and usernames is printed on the screen.
def userName():
for x in range(3):
last_name = input("What is your last name: ")
first_name = input("What is your first name: ")
username = first_name[:3] + "#" + last_name[-3:]
print(last_name + ", " + first_name)
print(username)
A beam of light travels in air and then passes through a piece of glass at an angle of 45 degrees to the normal. As the light passes from the air into the piece of glass, the light ray is bent, what is the angle of refraction measured from the normal?
Answer:
The angle of refraction measured from the normal is approximately 28.13°
Explanation:
The angle of refraction is the angle made by the refracted ray and the normal line drawn at the point where the ray passes through the interface of the two mediums
According to Snell's law, we have;
[tex]_1 n_2 = \dfrac{n_1}{n_2} = \dfrac{sin \, \theta _2}{sin \, \theta _1}[/tex]
n₁·sin (θ₁) = n₂·sin(θ₂)
Where;
₁n₂ = The refractive index of air to glass = 1.5
n₁ = The refractive index of air = 1
n₂ = The refractive index of glass ≈ 1.5
θ₁ = The angle of incidence = 45°
θ₂ = The angle of refraction measured from the normal
Therefore, we have;
1/1.5 = sin(θ₂)/sin(45°)
sin(θ₂) = sin(45°)/1.5 = (√2)/2/(3/2) = (√2)/3
∴ θ₂ = arcsin((√2)/3) ≈ 28.13°
The angle of refraction measured from the normal = θ₂ ≈ 28.13°.
why it is important for steel to go through a fluid phase as it is being produced.
Answer: It is important because the object must go through heat to be melted and then it should be put into a mold to be formed. Also, it go though heat to keep it from cracking and go to be cooled and harden

Answer:
A. 1 AWG
Explanation:
The larger the AGW number or wire gauge, the smaller the size of the wire
The largest conductor in the list is 1 American Wire Gauge (AWG)
What are conductors?Conductors are substances that allows electricity to flow through it.
In a conductor, electrical charge carriers, usually electrons or ions, move easily from atom to atom when voltage is applied.
In a simpler term conductors are substance that can conduct electricity.
American Wire Gauge (AWG) is the standard way to denote wire sizes.
Therefore, 1 American Wire Gauge (AWG) conducts more electricity in the list.

How is a digital representation of analog data a form of abstraction? Why is the quality of the photo, music, etc better when more samples are taken? Music is an example of analog data. What other examples of analog data can you think of?
Answer:
1. This is because non-essential parts of the analog data is cut of so as to represent the analog data digitally.
2. This is because it mirrors closely to the original analog material.
3. i. Temperature ii. Speed ii. Distance iv. Electric current
Explanation:
1. How is a digital representation of analog data a form of abstraction?
Digital representation of analog data is a form of abstraction because, since abstraction, which is the removal of non-essential parts of a material so as to reduce complexity, also non-essential parts of the analog data is cut of so as to represent the analog data digitally.
2.Why is the quality of the photo, music, etc better when more samples are taken?
The quality of these items is better because, as more samples are taken, it reduces the error in the sampling and the item(photo, music etc) mirrors closely to the original analog material.
3. What other examples of analog data can you think of?
i. Temperature ii. Speed ii. Distance iv. Electric current

It is a good idea to deliberately type sum errors so we can see how the spellchecker works. When the spellchecker encounters a word it doesn't recognize the correct spelling or words in its dictionary that are similarly spelled and displays a list of those words . The most likely match highlighted, the contents of the list determined only by spelling.
Any instances of terms that seem inappropriate in context are completely coincidental

(A)The title of your email/summary of what you need
(B) The persons name you are sending an email to
(C) The question you are asking
I will mark brainliest
Answer:
the correct answer is: (A) The title/summary of what you need.
Explanation:
The subject is what the receiver see's when going across the email. Putting the summary of what the email is about in subject allows them to see what the email is mainly about seeing if they should continue reading the email or not. So providing the summary pf the email lets the receiver know what the email is about. Hope this helps! :D

(Print distinct numbers) Write a program that reads in integers separated by a space in one line and displays distinct numbers in their input order and separated by exactly one space (i.e., if a number appears multiple times, it is displayed only once). Hint: Read all the numbers and store them in list1. Create a new list list2. Add a number in list1 to list2. If the number is already in the list, ignore it.
Answer:
Following are the program to the given question:
num = input("Enter numbers: ")#defining a variable num for input value
list1 = num.split()#defining a list1 that adds value in list1
list2 = []#defining an empty list list2
for j in range(len(list1)):#defining a for loop that checks the list value in range
if not list1[j] in list2:# use if block that checks multiple value
list2.append(list1[j])#add value in list2
print("The distinct numbers are: ")#print message
for j in range(len(list2)):#defining for loop for print list value
print(list2[j])#print list value
Output:
Enter numbers: 1 22 55 7 22 1 1 2 3
The distinct numbers are:
1
22
55
7
2
3
Explanation:
In the above-code, a "num" variable is defined, that takes inputs from the console screen, and in the next step, "list1 and list2" is defined. In the "list1" it adds num variable value a into the list.
In the next step, a for loop is defined that checks the list value in range , and define an if block, that checks multiple value and add value into the list2, and in the next step, the for loop is defined that prints the list2 values.

Answer:
Network.
Explanation:
The Transmission Control Protocol/Internet Protocol (TCP/IP) model is a standard networking protocol which allows network devices such as routers, switches, and host computers to interconnect and communicate with one another over a network. The Transmission Control Protocol/Internet Protocol (TCP/IP) model comprises of four (4) layers and these includes;
I. Application layer.
II. Transport layer.
III. Internet layer.
IV. Network layer.
The network layer in the Transmission Control Protocol/Internet Protocol (TCP/IP) model is responsible for delivering data between two nodes.
Basically, this layer known as network layer is the fourth layer of the Transmission Control Protocol/Internet Protocol (TCP/IP) model and it is typically responsible for the transmission of packets from one network device to another.

Explanation:
is it safe for me to use normal glue to stick things on my laptop like stickers or pics?
Answer:
I think you should be fine, as long as you're just sticking it to the backside of your laptop. (For MacBooks, this is the part of the laptop with the apple symbol.) You can easily wash glue off with a cleaner such as Goo Gone or Pledge. There's better solutions, like ordering a case for your computer and putting the stickers on there, but I guess it's fine to stick them onto your computer. I'll attach a photo of an example of case with stickers.
Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day, and feel free to comment any questions below you may have. :)
It is safe to use normal glue to stick things on my laptop like stickers or pics. On the back of the laptop cover, this glue can be used.
What are glues?Any non-metallic substance applied to one or both sides of two distinct items that binds them together and prevents their separation is an adhesive, also known as glue, cement, mucilage, or paste.
superglue, sometimes called cyanoacrylate, is a kind of adhesive that joins quickly and may be used on a range of surfaces and materials. This fast-bonding glue has the advantage of eliminating the need for nails, clamps, and other fasteners. Superglues are waterproof, quick-setting, and will dry clear.
Therefore, stickers and pictures can be safely adhered on my laptop using regular adhesive. This glue can be applied to the laptop cover's rear.
