A. counter module
B. while loop
C. for loop
D. mean module
Answers
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is A: counter module.
Counter module in python or Python counter is a container that holds the count of each of the elements present in the container. It is a sub-class available in the dictionary class. Jamal can use this module in Python to write a program that will find the 10 most common words in Romeo and Juliet.
Other options are not correct because:
While loop: while loop only iterates its body until a specific condition is met. For loop is used to iterate to a pre-specified condition and iterate until the condition is reached. While the mean module of Python is used to calculate mean and average.

Answers
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer to this question is the Text box.
You can insert a text box as an object in your document, type text in it and you can format it in the same way you would do for other objects.
You can insert the text box using the Insert tab then under Shapes that you can find under the Illustrations group. You can then find Text Box under basic shapes.
While the other options are not correct because:
Formatting box allows you to format the object, text holder and typing box does not mean in this context because text holder is something that can hold the text such as shapes or text box, etc. but these terms are not used in word or in a document.
How did DDE devices have made our daily life easier?
Answers
Answer:
The answer to this question is given below in the explanation section.
Explanation:
DDE (direct data entry) devices are the devices that read data from a source and transfer it directly into the computer. Unlike, other input devices which require physical interaction which requires you to move physically or to do something for an output or feeding data into a computer.
The DDE devices require no hard work while taking input into the computer as compared to other input devices. These DDE devices made our life very easy. Because these devices take input accurately and there are no chances of human error.
The example of DDE devices are magnetic stripe reader, chip reader, Pin pads, optical mark reader, and barcode reader, etc.
These devices have brought great advantages to human life. Because by using these data entry devices, information can be put into very quickly, more accurate than typing and information of the whole page transferred .very quickly and accurately into the system. These devices are also more secure and can hold lots of data, and the data is protected with the PIN (personal identification number). These are also used in ATM machines, handheld, and entry doors.

Write a loop that sets newScores to oldScores shifted once left, with element 0 copied to the end. Ex: If oldScores
Answers
Answer:
Explanation:
The following is written in Java. It is a method/function that takes the oldScore as an int input. It turns it into a String, separates all the digits, puts them into an array. Then adds the first digit to the end and removes it from the beginning, thus shifting the entire score one to the left. Then it turns the String variable back into an Integer called finalScore and prints it out.
public static void newScore(int oldScore) {
ArrayList<Integer> newScore = new ArrayList<>();
String stringOldScore = String.valueOf(oldScore);
for (int x = 0; x < stringOldScore.length(); x++) {
newScore.add(Integer.parseInt(String.valueOf(stringOldScore.charAt(x))));
}
newScore.add(newScore.get(0));
newScore.remove(0);
String newScoreString = "";
for (int x:newScore) {
newScoreString += String.valueOf(x);
}
int finalScore = Integer.parseInt(newScoreString);
System.out.println(finalScore);
}

Your manager has tasked you with implementing security controls to mitigate IP spoofing attacks against your network. IP spoofing is a method of attack that involves sending packets to a target network while hiding the attacker's address using a false source address.
What method outlined would achieve anti-spoofing, to mitigate private IP spoofing attacks against your network?
Answers
Answer:
You can setup firewall rules with for example iptables on Linux. The rules should block source addresses of private IP ranges such as 192.168.*.* and 10.*. *. * etc. Check private IP ranges for full list.
It will however not guarantee prevention of IP spoofing in general as its not possible to prevent such attacks. Its the responsibility of ISPs. But the question asked for private IP spoofing and then the above works.

Write a program with 2 separate functions which compute the GCD (Greatest Common Denominator) and the LCM (Lowest Common Multiple) of two input integers.
Answers
Answer:
The program written in Python is as follows
def GCD(num1, num2):
small = num1
if num1 > num2:
small = num2
for i in range(1, small+1):
if((num1 % i == 0) and (num2 % i == 0)):
gcd = i
print("The GCD is "+ str(gcd))
def LCM(num1,num2):
big = num2
if num1 > num2:
big = num1
while(True):
if((big % num1 == 0) and (big % num2 == 0)):
lcm = big
break
big = big+1
print("The LCM is "+ str(lcm))
print("Enter two numbers: ")
num1 = int(input(": "))
num2 = int(input(": "))
GCD(num1, num2)
LCM(num1, num2)
Explanation:
This line defines the GCD function
def GCD(num1, num2):
This line initializes variable small to num1
small = num1
This line checks if num2 is less than num1, if yes: num2 is assigned to variable small
if num1 > num2:
small = num2
The following iteration determines the GCD of num1 and num2
for i in range(1, small+1):
if((num1 % i == 0) and (num2 % i == 0)):
gcd = i
This line prints the GCD
print("The GCD is "+ str(gcd))
This line defines the LCM function
def LCM(num1,num2):
This line initializes variable big to num2
big = num2
This line checks if num1 is greater than num2, if yes: num1 is assigned to variable big
if num1 > num2:
big = num1
The following iteration continues while the LCM has not been gotten.
while(True):
This if statement determines the LCM using modulo operator
if((big % num1 == 0) and (big % num2 == 0)):
lcm = big
break
big = big+1
This line prints the LCM of the two numbers
print("The LCM is "+ str(lcm))
The main starts here
This line prompts user for two numbers
print("Enter two numbers: ")
The next two lines get user inputs
num1 = int(input(": "))
num2 = int(input(": "))
This calls the GCD function
GCD(num1, num2)
This calls the LCM function
LCM(num1, num2)

a) 1
b) 2
c) 3
d) 4
Answers
Answer:
C = 3
Explanation:
The maximum number of physical memory accesses that may be caused by this single instruction is ; 3
This is because In the case of loading two values into R2 and R3 there is need for their memories to be accessed and after execution R1 value there will be a write back into memory hence another memory is also accessed and that makes the number of Physical memories accessed to be three(3) in Total

A scared kangaroo clears a fence that is 2.44 meters tall. What is the vertical component of the kangaroos velocity at take off ? If the horizontal component of the kangaroos velocity is 4.80 m per s at what angle did the kangaroo take off the ground? (hint: at its maximum height the kangaroos vertical velocity is 0)
Answers
Answer:
a) The vertical component of the kangaroo's velocity at take off is approximately 4.982 meters per second.
b) The angle at which the kangaroo took off the ground is approximately 46.066º.
Explanation:
a) According to the statement, the kangaroo has an initial horizontal velocity and jumps to overcome the fence until velocity becomes zero. If effects from non-conservative forces can be neglected, then we represent the situation of the kangaroo by Principle of Energy Conservation:
[tex]K_{1}+U_{g,1} = K_{2}+U_{g,2}[/tex] (Eq. 1)
Where:
[tex]K_{1}[/tex], [tex]K_{2}[/tex] - Initial and final translational kinetic energies, measured in joules.
[tex]U_{g,1}[/tex], [tex]U_{g,2}[/tex] - Initial and final gravitational potential energies, measured in joules.
By definitions of translational kinetic and potential gravitational energies, we expand and simplify the equation above:
[tex]\frac{1}{2}\cdot m\cdot [(v_{1,x}^{2}+v_{1,y}^{2})-(v_{2,x}^{2}+v_{2,y}^{2})] = m\cdot g \cdot (y_{2}-y_{1})[/tex]
[tex]\frac{1}{2}\cdot [(v_{1,x}^{2}+v_{1,y}^{2})-(v_{2,x}^{2}+v_{2,y}^{2})] = g \cdot (y_{2}-y_{1})[/tex] (Eq. 2)
Where:
[tex]m[/tex] - Mass of the kangaroo, measured in kilograms.
[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.
[tex]y_{1}[/tex], [tex]y_{2}[/tex] - Initial and final heights of the kangaroo above the ground, measured in meters.
[tex]v_{1,x}[/tex], [tex]v_{1,y}[/tex] - Vertical and horizontal initial velocities, measured in meters per second.
[tex]v_{2,x}[/tex], [tex]v_{2,y}[/tex] - Vertical and horizontal final velocities, measured in meters per second.
If we know that [tex]v_{1,x} = 4.80\,\frac{m}{s}[/tex], [tex]v_{2, x} = 0\,\frac{m}{s}[/tex], [tex]v_{2,y} = 0\,\frac{m}{s}[/tex], [tex]g = 9.807\,\frac{m}{s^{2}}[/tex] and [tex]y_{2}-y_{1} = 2.44\,m[/tex], then (Eq. 2) is reduced into this:
[tex]11.52+0.5\cdot v_{1,y}^{2}=23.929[/tex]
Lastly, we solve for [tex]v_{1,y}[/tex]:
[tex]0.5\cdot v_{1,y}^{2}=12.409[/tex]
[tex]v_{1,y}^{2} = 24.818[/tex]
[tex]v_{1,y} \approx 4.982\,\frac{m}{s}[/tex]
The vertical component of the kangaroo's velocity at take off is approximately 4.982 meters per second.
b) The angle at which the kangaroo took off the ground ([tex]\theta[/tex]), measured in sexagesimal degrees, is obtained by the following inverse trigonometric relation:
[tex]\theta =\tan^{-1}\left(\frac{v_{1,y}}{v_{1,x}} \right)[/tex] (Eq. 3)
[tex]\theta = \tan^{-1}\left(\frac{4.982\,\frac{m}{s} }{4.80\,\frac{m}{s} } \right)[/tex]
[tex]\theta \approx 46.066^{\circ}[/tex]
The angle at which the kangaroo took off the ground is approximately 46.066º.

Write a application that can determine if a 5 digit number you input is a palindrome. If the number is a palindrome then print "The number is a palindrome." If it is not then print "The number is NOT a palindrome"
Answers
Answer:
Written in Python:
num = int(input("Number: "))
strnum = str(num)
if len(strnum) !=5:
print("Length must be 5")
else:
if(strnum[::-1] == strnum):
print("The number is a palindrome.")
else:
print("The number is NOT palindrome.")
Explanation:
This prompts user for input
num = int(input("Number: "))
This converts user input to string
strnum = str(num)
This checks the length of the string
if len(strnum) !=5:
print("Length must be 5") If length is not 5, this prompt is printed
else:If otherwise
if(strnum[::-1] == strnum): The compares the string reversed with the original
print("The number is a palindrome.") If both are the same, this line is executed
else:
print("The number is NOT palindrome.") If otherwise, this line is executed

A flashlight bulb uses 2.4 W of power when the current in the bulb is 0.8 A. What is the voltage difference?
Answers
Answer:
3 Volts.
Explanation:
Answer:
3 Volts
Explanation:
Because Power = Voltage x Current, so if you substitute the values into the equation, it would be :
2.4 W = Voltage x 0.8 A
Then if you rearrange the equation, it would be :
2.4 W / 0.8 A = Voltage
Which is :
3 V = Voltage
