Answer:

hi your question lacks the image and options here is the complete question

Study the images of two different fronts.

Cold

Warm

Item A

Item B

Based on arrow movement, why is the front shown in item A different from the front shown in item B?

A) Warm air rises above cold air in item A, while two air masses collide in item B.

B) Cold air mixes with warm air in item A, while two air masses barely move in item B.

C) Warm air is pushed upward near cold air in item A, while a boundary forms in item B.

D) Two air masses form a boundary in item A, while warm air rises above cold air in item B.

the answer is D

Explanation:

Two air masses form a boundary in item A while warm air rises above cold air in item B. this is because the two air masses form a boundary in Item A because the the air masses of the cold and warm air are equal hence the formation of the boundary been seen in item A.

In Item B it is seen that the warm air rises/moves above the cold air because air is lighter in the atmosphere when they are warmer than usual,leading to it rising above cold air when together in same environment.

Explain how QoS might be implemented

Artist 52 [7]

Answer:

The quality of service basically provide the sufficient quality in the IP network and it is also known as traffic shaping. As, it assign the priority to every device and the services in the network. It basically recognize the several types of the traffic moving in the network.

The implementation of quality of service is basically done in many network applications by reserve the bandwidth and specific path in the network system.

The various network device control the packet flow so that the network resources can easily accept packets in the network.

Write a Python function check_subset() that takes in two Python lists, representing sets of integers, A and B. Your function sho

wlad13 [49]

Answer:

def check_subset(l1, l2):
status = False
count = 0
if(len(l1) > len(l2)):
for x in l2:
for y in l1:
if x == y:
count += 1
if(count == len(l2)):
return True
else:
return False
else:
for x in l1:
for y in l2:
if x==y:
count += 1
if(count == len(l1)):
return True
else:
return False
print(check_subset([1,4,6], [1,2,3,4,5,6]))
print(check_subset([2,5,7,9,8], [7,8]))
print(check_subset([1, 5, 7], [1,4,6,78,12]))

Explanation:

The key idea of this solution is to create a count variable to track the number of the elements in a shorter list whose value can be found in another longer list.

Firstly, we need to check which list is shorter (Line 4). If the list 2 is shorter, we need to traverse through the list 2 in an outer loop (Line 5) and then create another inner loop to traverse through the longer list 1 (Line 6). If the current x value from list 2 is matched any value in list 1, increment the count variable by 1. After finishing the outer loop and inner loop, we shall be able to get the total count of elements in list 2 which can also be found in list 1. If the count is equal to the length of list 2, it means all elements in the list 2 are found in the list 1 and therefore it is a subset of list 1 and return true (Line 10-11) otherwise return false.

The similar process is applied to the situation where the list 1 is shorter than list 2 (Line 15-24)

If we test our function using three pairs of input lists (Line 26-28), we shall get the output as follows:

True

False

What is a massive, room-sized computer that process and store enormous amounts of bulk data and information?

kipiarov [429]

Answer:

Mainframe Computer

Explanation:

The Mainframe Computers are designed for bulk data processing with high speed and storing huge data that can't be performed by other regular PCs. They can run multiple instances of operating systems at the same time. They are used for application such as accounting, business transaction, information retrieval, airlines for the seat reservation and engineering computation.

Create an Automobile class for a dealership. Include fields for an ID number, make, model, color, year, vin number, miles per ga

aliya0001 [1]

Answer:

public class TestAutomobiles {

public static void main(String args[]) {

Automobile obj = new Automobile(1, "Wolkswagen", "Golf", 2007, "GR1GR", 20, 120, "Grey");

System.out.println("Initial Speed: " + obj.getSpeed());

System.out.println("Current Speed with acceleration 100: " + obj.accelerate(100));

System.out.println("Current Speed after using brake : " + obj.brake());

}

class Automobile {

private int idNumber, year, milesPerGallon, speed = 0;

private String model, vinNumber, make, color;

public void setIdNumber(int idNumber){

if (idNumber >= 0 && idNumber <= 9999)

this.idNumber = idNumber;

else this.idNumber = 0;

}

public void setModel(String model){

this.model = model;

}

public void setYear(int year){

if (year >= 2000 && year <= 2017)

this.idNumber = idNumber;

else this.year = 0;

}

public void setVinNumber(String vinNumber){

this.vinNumber = vinNumber;

}

public void setMilesPerGalon(int milesPerGallon){

if (milesPerGallon >= 10 && year <= 60)

this.milesPerGallon = milesPerGallon;

else this.milesPerGallon = 0;

}

public void setSpeed(int speed){

this.speed = speed;

}

public void setMake(String make){

this.make = make;

}

public void setColor(String color){

this.color = color;

}

public int getIdNumber(){return idNumber;}

public String getModel(){return model;}

public int getYear(){return year;}

public String getVinNumber(){return vinNumber;}

public int getMilesPerGallon(){return milesPerGallon;}

public int getSpeed(){return speed;}

public String getMake(){return make;}

public String getColor(){return color;}

public int accelerate() {

setSpeed(speed + 5);

return speed;

}

public int brake() {

setSpeed(speed - 5);

return speed;

}

public int accelerate(int s) {

setSpeed(speed + s);

return speed;

}

public int brake(int s) {

setSpeed(speed - s);

return speed;

}

public Automobile(int idNumber, String make, String model, int year, String vinNumber, int milesPerGallon, int speed, String color){

setIdNumber(idNumber);

setModel(model);

setYear(year);

setVinNumber(vinNumber);

setMilesPerGalon(milesPerGallon);

setSpeed(speed);

setMake(make);

setColor(color);

}

Explanation:

Required variables are declared as private members.

Their setters and getter are created.

Two accelearate and two break methods are created.

One constructor taking all variables as parameter is created.

In the main, I tested a few functions to check if they work properly.
