String), a year (type String), and a price (double). Provide a constructor that initializes the three
instance variables. Provide a set and a get method for each instance variable. If the price is not positive,
do not set its value. Write a test application named CarApplication that demonstrates class Car’s capabilities. Create two Car objects and display each object’s price. Then apply a 5% discount on the
price of the first car and a 7% discount on the price of the second. Display each Car’s price again.
Answer:
Here is an example of a class called Car that includes three instance variables: model (type String), year (type String), and price (double). The class includes a constructor that initializes the three instance variables, as well as set and get methods for each instance variable:
Car.java:
public class Car {
private String model;
private String year;
private double price;
// Constructor
public Car(String model, String year, double price) {
this.model = model;
this.year = year;
if (price > 0) {
this.price = price;
}
}
// Set methods
public void setModel(String model) {
this.model = model;
}
public void setYear(String year) {
this.year = year;
}
public void setPrice(double price) {
if (price > 0) {
this.price = price;
}
}
// Get methods
public String getModel() {
return model;
}
public String getYear() {
return year;
}
public double getPrice() {
return price;
}
}

public class CarApplication {
public static void main(String[] args) {
Car car1 = new Car("Ford", "2020", 30000.0);
Car car2 = new Car("Toyota", "2019", 35000.0);
// Display the price of each car
System.out.println("Car 1: " + car1.getPrice());
System.out.println("Car 2: " + car2.getPrice());
// Apply a 5% discount on the price of car 1
car1.setPrice(car1.getPrice() * 0.95);
// Apply a 7% discount on the price of car 2
car2.setPrice(car2.getPrice() * 0.93);
// Display the price of each car again
System.out.println("Car 1: " + car1.getPrice());
System.out.println("Car 2: " + car2.getPrice());
}

A current is induced in a wire by moving the wire through a magnetic field. Which is one factor that affects the direction of the current?
the direction in which the wire moves
the thickness of the wire
the direction of the needle on an ammeter

Answer:
the direction in which the wire moves
One factor that affects the direction of the current is the direction in which the wire moves. Thus, an option first is correct.
What is a magnetic field?The area of space known as the magnetic field is where an item experiences the magnetic force when it is near a magnetic substance.
Numerous variables affect the direction of electric current flow in a conductor wire carrying electricity. Current will flow in the direction of a particular wire whether it is moving in or out.
This implies that altering the current's direction likewise alters the magnetic field's direction. Both sides of the magnet will be repelled by the magnetic field by bending away from the wire because the magnetic field produced by the current of electricity in the wire alters directions around the wire.
Therefore, a factor that affects the direction of the current is the direction in which the wire moves. Hence, an option first is correct.

Determine whether the statement is true or false. If f has an absolute minimum value at C, then f'(c) = 0. True False
The statement on the absolute minimum value is False.
Absolute Minima and Maxima:
We occasionally encounter operations with hills and valleys. Hill and valley points in polynomial functions typically have many locations. We are aware that these places, which can be categorized as maxima or minima, are the function's crucial points. The valley points are referred to as minimas and the hill points as maxima. We must determine the locations of the function's global maxima and global minima, which are known as the minimum and maximum values, respectively, due to the fact that there are several maxima and minima.
Critical Points:
When the derivative of a function f(x), for example, reaches 0, those locations are said to be its crucial points. Both maxima and minima are possible for these places. The second derivative test determines if a crucial point is a minima or maximum. Since the derivative of the function might occur more than once, several minima or maxima are possible.
Extrema Value Theorem:
Under specific circumstances, the extrema value theorem ensures that a function has both a maximum and a minimum. Although this theorem just states that the extreme points will occur, it does not specify where they will be. The theorem asserts,
If a function f(x) is continuous on a closed interval [a, b], then f(x) has both at least one maximum and minimum value on [a, b].

Examine the experience of shopping online vs shopping in traditional environment. Imagine that you have decided to purchase a digital camera or any other item of your choice, first shop for the camera in traditional manner.
Describe how you would do so (eg: how would you gather the necessary information, you would need to choose the particular item, what stores you would visit, how long it would take, price etc)
Next, shop for the item on the web or via a mobile app.
Compare and contrast your experiences, what were the advantages and disadvantages of each.
What would prefer and why?
Answer:
Explanation:
If I had to buy, let’s say an iPad, I would visit the official store. First of all, I would take a closer look at the product, revising it carefully, if it feels right and if it meets my needs. Then I would ask for the price if they have a discount or any sale upcoming or payment plan. If everything meets my requirements I would buy the item. On the other hand, if there weren’t any official stores around the place I live in, I would visit three different department stores, preferably where they have the product of my interest displayed, also I would ask about the price and/or payment plan or discounts and availability. I must mention that cost is an important aspect to make a decision on where to buy the item. All of this process would take about 1 or 2 days at most.
Advantages
-You can see, feel, check the product to dissipate any doubts, there are people willing to answer any question and help to make a better choice.
Get the product at the same moment you are paying for it and if you want to you can use/wear it immediately.
Disadvantages
If they are out of stock of the item of your interest, there is a chance you will have to wait a long time for it, although it could happen the store won’t have the product available again.
The offers are not as wide as on the web sites.
Shopping on the web or via a mobile app
It is almost the same as shopping in a traditional manner, the greater differences are that there are more virtual places/shops online to compare prices and availability and sometimes they have great offers, because of the competition. Generally, the items are cheaper than a department store.
This process could take about a week, especially if you are waiting for a specific offer.
Advantages
There are lots of options, lots of different online stores, that increase the chances to get a good offer or an item with better characteristics at the same price; if you don’t find availability in one web you can find it in another in no time.
There is no need to leave your house or put on pause your busy schedule, as you will receive the item at your door.
Disadvantages
You can’t check the product given they only display a few pictures of it and a brief description, there is no one to answer your doubts about the item, basically, the decision relies on your research and recommendations of the product.
After making your purchase, you will have to wait a few days to receive your item at home or the workplace. Sometimes happens the store confuses your order sending a different product or other with different characteristics, resulting in having to return the item and wait days to get what you order in the first place.
Explanation:
Which did I prefer and why?
Considering the advances in technology, I prefer to shop online, there I can find what I'm looking for and of course, they have a great offers, too. Besides, with day to day occupations I barely have time to go to a department store, so is easier to access using a computer or an app on the smartphone.

3. What abstraction does an OS provide for the disk space?
Abstraction refers to the process of removing elements of a code or program that are irrelevant or distract from more important elements.
What are the abstractions OS provides?By virtualizing the CPU, the operating system provides this abstraction. By running one process, then stopping it and starting another, and so on, the operating system can create the illusion of many virtual CPUs when there is only one physical CPU (or a few).A memory abstraction is a layer of abstraction between program execution and memory that provides a different "view" of a memory location depending on the execution context in which the memory access is performed.Many operating systems include a hardware abstraction layer, which eliminates the need to modify the OS kernel in order to run programs on computers with different hardware architectures. It is a device driver that allows programs to connect to hardware peripherals through a consistent interface.To learn more about abstraction refer to :
