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°.

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
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
Explanation:
Write a C++ program to add two integers. Make a function add() to add integers and display sum in main() function.
Answer:
In C++:
#include <iostream>
using namespace std;
int add(int a, int b){
int c = a + b;
return c;
}
int main(){
int a, b;
cout<<"Enter two numbers: ";
cin>>a;
cin>>b;
cout<<add(a,b);
return 0;
}
Explanation:
The add() function begins here
int add(int a, int b){
This adds the two integers
int c = a + b;
This returns the sum of the two integers
return c;
}
The main begins here
int main(){
This declares two numbers
int a, b;
This prompts user for two numbers
cout<<"Enter two numbers: ";
The next two lines gets the two numbers
cin>>a;
cin>>b;
This gets the sum of the two numbers from the add() function. The sum is also printed
cout<<add(a,b);
return 0;
}

Information system are too important to be left to computer specialist.Do you agree? Why or why not.
Answer:
Yes
Explanation:
Yes, information systems control all the information that goes through the system. This information is incredibly valuable and is very vast. Computer specialists are trained in helping others with regular computer problems both in hardware and software. They are not trained to analyze and handle giant databases of information. If they make a single mistake they can cost the organization millions of dollars in damages. Therefore, yea it is very risky to be left to a computer specialist.
