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°.
If you came across an article that discussed the benefits of studying the night before a test rather than the morning of, what could you do to form your own opinion about such information? A. Do your own research including reading articles related to the same topic. B. Ask a trusted family member their opinion after they read the article. C. Check different social media accounts for articles on sleep studies. D. Read another article on this topic written by the same journalist.
Answer:
A. Do your own research including reading articles related to the same topic.
Explanation:
To confirm online information that is not made by reputable experts, professionals, journals, or websites, it is always recommended to cross-check such information carefully. To do that is to make research on the same topic and confirm if the actual information is the same.
Hence, in this case, the correct answer is "Do your own research including reading articles related to the same topic."

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
Some Tiny College staff employees are information technology (IT) personnel.

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.

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;
}
