Answer:
mass = float(input("Mass: "))
velocity = float(input("Velocity: "))
momentum = mass * velocity
print("The object's momentum is ", momentum)
Explanation:
*The code is in Python.
Ask the user to enter the mass and velocity. Since both of the values could be decimal numbers, cast them as float
Calculate the momentum using given information, multiply mass by velocity
Print the momentum as example output

Answer:
The SANS Top 20 Critical Security Controls For Effective Cyber Defense
Explanation:
Password/PIN Policy
Developing a password and personal identification number policy helps ensure employees are creating their login or access credentials in a secure manner. Common guidance is to not use birthdays, names, or other information that is easily attainable.
Device Controls
Proper methods of access to computers, tablets, and smartphones should be established to control access to information. Methods can include access card readers, passwords, and PINs.
Devices should be locked when the user steps away. Access cards should be removed, and passwords and PINs should not be written down or stored where they might be accessed.
Assess whether employees should be allowed to bring and access their own devices in the workplace or during business hours. Personal devices have the potential to distract employees from their duties, as well as create accidental breaches of information security.
As you design policies for personal device use, take employee welfare into consideration. Families and loved ones need contact with employees if there is a situation at home that requires their attention. This may mean providing a way for families to get messages to their loved ones.
Procedures for reporting loss and damage of business-related devices should be developed. You may want to include investigation methods to determine fault and the extent of information loss.
Internet/Web Usage
Internet access in the workplace should be restricted to business needs only. Not only does personal web use tie up resources, but it also introduces the risks of viruses and can give hackers access to information.
Email should be conducted through business email servers and clients only unless your business is built around a model that doesn't allow for it.
Many scams and attempts to infiltrate businesses are initiated through email. Guidance for dealing with links, apparent phishing attempts, or emails from unknown sources is recommended.
Develop agreements with employees that will minimize the risk of workplace information exposure through social media or other personal networking sites, unless it is business-related.
Encryption and Physical Security
You may want to develop encryption procedures for your information. If your business has information such as client credit card numbers stored in a database, encrypting the files adds an extra measure of protection.
Key and key card control procedures such as key issue logs or separate keys for different areas can help control access to information storage areas.
If identification is needed, develop a method of issuing, logging, displaying, and periodically inspecting identification.
Establish a visitor procedure. Visitor check-in, access badges, and logs will keep unnecessary visitations in check.
Security Policy Reporting Requirements
Employees need to understand what they need to report, how they need to report it, and who to report it to. Clear instructions should be published. Training should be implemented into the policy and be conducted to ensure all employees understand reporting procedures.
Empower Your Team
One key to creating effective policies is to make sure that the policies are clear, easy to comply with, and realistic. Policies that are overly complicated or controlling will encourage people to bypass the system. If you communicate the need for information security and empower your employees to act if they discover a security issue, you will develop a secure environment where information is safe.

Write a method that evaluates to true or false depending on whether a box completely fits inside another:
public boolean nests( Box outsideBox )
This is potentially a difficult method, since the box may fit or not fit depending on how it is rotated. To simplify the method, write it so that it returns true if the two boxes nest without considering rotations (so height is compared to height, length compared to length, and so on.)
Answer:
box outside box
Explanation:
It is used to display a window with many options, or buttons, in Easy GUI. It can be used in situations when it is necessary to determine which option is the first selection because it returns 1 for buttons with index 0 and 0 for buttons with other indexes.
What public boolean nests contain box outside box?One of the built-in data types in Python is the Boolean type. It serves as a representation of an expression's truth value. For instance, the statement 0 == 1 is False while the statement 1 = 2 is True.
To write effective Python code, one must have a solid understanding of how Python's Boolean values operate.
A boolean value describes the checked attribute. Whenever it is present, it indicates that a checkbox next to an input> element should be selected (checked) before the page loads.
Therefore, The checked attribute can be applied to both checkbox and radio input types. Additionally, JavaScript can be used to modify the checked attribute after the page has loaded.

Answer:
An array.
Explanation:
An array can be defined as a structure that organizes data in a list that is commonly 1-dimensional or 2-dimensional.
Simply stated, an array refers to a set of memory locations (data structure) that comprises of a group of elements with each memory location sharing the same name. Therefore, the elements contained in array are all of the same data type e.g strings or integers.
Basically, in computer programming, arrays are typically used by software developers to organize data, in order to search or sort them.
Binary search is an efficient algorithm used to find an item from a sorted list of items by using the run-time complexity of Ο(log n), where n is total number of elements. Binary search applies the principles of divide and conquer.
In order to do a binary search on an array, the array must first be sorted in an ascending order.
Hence, array elements are mainly stored in contiguous memory locations on computer.
g n this program, you will prompt the user for three numbers. You need to check and make sure that all numbers are equal to or greater than 0 (can use an if or if/else statement for this). You will then multiply the last two digits together, and add the result to the first number. The program should then start over, once again asking for another three numbers. This program should loop indefinitely in this way. If the user enters a number lower than 0, remind the user that they need to enter a number greater than or equal to 0 and loop the program again.
Answer:
In Python:
loop = True
while(loop):
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
result = nm2 * nm3 + nm1
print("Result: "+str(result))
loop = True
else:
print("All inputs must be greater than or equal to 0")
loop = True
Explanation:
First, we set the loop to True (a boolean variable)
loop = True
This while loop iterates, indefinitely
while(loop):
The next three lines prompt user for three numbers
nm1 = float(input("Number 1: "))
nm2 = float(input("Number 2: "))
nm3 = float(input("Number 3: "))
The following if condition checks if all of the numbers are greater than or equal to 0
if (nm1 >= 0 and nm2 >= 0 and nm3 >= 0):
If yes, the result is calculated
result = nm2 * nm3 + nm1
... and printed
print("Result: "+str(result))
The loop is then set to true
loop = True
else:
If otherwise, the user is prompted to enter valid inputs
print("All inputs must be greater than or equal to 0")
The loop is then set to true
loop = True
We have looked at several basic design tools, such as hierarchy charts, flowcharts, and pseudocode. Each of these tools provide a different view of the design as they work together to define the program. Explain the unique role that each design tool provides (concepts and/or information) to the design of the program.
Answer:
Answered below
Explanation:
Pseudocode is a language that program designers use to write the logic of the program or algorithms, which can later be implemented using any programming language of choice. It helps programmers focus on the logic of the program and not syntax.
Flowcharts are used to represent the flow of an algorithm, diagrammatically. It shows the sequence and steps an algorithm takes.
Hierarchy charts give a bird-eye view of the components of a program, from its modules, to classes to methods etc.

According to the vulnerability assessment methodology, vulnerabilities are determined by which 2 factors?
Answer:
3 and 60!
Explanation:
Consider the definition of the Person class below. The class uses the instance variable adult to indicate whether a person is an adult or not.
public class Person
{
private String name;
private int age;
private boolean adult;
public Person (String n, int a)
{
name = n;
age = a;
if (age >= 18)
{
adult = true;
}
else
{
adult = false;
}
}
}
Which of the following statements will create a Person object that represents an adult person?
a. Person p = new Person ("Homer", "adult");
b. Person p = new Person ("Homer", 23);
c. Person p = new Person ("Homer", "23");
d. Person p = new Person ("Homer", true);
e. Person p = new Person ("Homer", 17);
Answer:
b. Person p = new Person ("Homer", 23);
Explanation:
The statement that will create an object that represents an adult person would be the following
Person p = new Person ("Homer", 23);
This statement creates a Person object by called the Person class and saving it into a variable called p. The Person method is called in this object and passed a string that represents the adult's name and the age of the adult. Since the age is greater than 18, the method will return that adult = true.
The other options are either not passing the correct second argument (needs to be an int) or is passing an int that is lower than 18 meaning that the method will state that the individual is not an adult.
In this programming assignment, you will write a simple program in C that outputs one string. This assignment is mainly to help you get accustomed to submitting your programming assignments here in zyBooks. Write a C program using vim that does the following. Ask for an integer input from the user. Do not print any prompt for input. If the number is divisible by 3, print the message CS If the number is divisible by 5, print the message 1714 If the number is divisible by both 3
Answer:
In C:
#include <stdio.h>
int main() {
int mynum;
scanf("%d", &mynum);
if(mynum%3 == 0 && mynum%5 != 0){
printf("CS"); }
else if(mynum%5 == 0 && mynum%3 != 0){
printf("1714"); }
else if(mynum%3 == 0 && mynum%5 == 0){
printf("CS1714"); }
else {
printf("ERROR"); }
return 0;
}
Explanation:
This declares mynum as integer
int mynum;
This gets user input
scanf("%d", &mynum);
This condition checks if mynum is divided by 3. It prints CS, if true
if(mynum%3 == 0 && mynum%5 != 0){
printf("CS"); }
This condition checks if mynum is divided by 5. It prints 1714, if true
else if(mynum%5 == 0 && mynum%3 != 0){
printf("1714"); }
This condition checks if mynum is divided by 3 and 5. It prints CS1714, if true
else if(mynum%3 == 0 && mynum%5 == 0){
printf("CS1714"); }
This condition checks if num cannot be divided by 3 and 5. It prints ERROR, if true
else {
printf("ERROR"); }

What is the relationship between an object and class in an OOP program?
The object contains classes.
The object and class are the same thing.
The object is used to create a class.
The object in a program is called a class.
Answer:
D. The object in a program is called a class.
Explanation:
Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995. Java was designed by a software engineer called James Gosling and it is originally owned by Oracle.
In object-oriented programming (OOP) language, an object class represents the superclass of every other classes when using a programming language such as Java. The superclass is more or less like a general class in an inheritance hierarchy. Thus, a subclass can inherit the variables or methods of the superclass.
Basically, all instance variables that have been used or declared in any superclass would be present in its subclass object.
Hence, the relationship between an object and class in an OOP program is that the object in a program is called a class.
For example, if you declare a class named dog, the objects would include barking, color, size, breed, age, etc. because they are an instance of a class and as such would execute a method defined in the class.
Write a program that prompts the user to enter a fraction in the following format (x/y). You may assume that the user will input numbers and a slash, but your program should deal with spaces. Use String methods to parse out the numerator and denominator (e.g. indexOf(), trim(), substring() etc.) Once you have the numerator and denominator, your program will determine whether the number is a proper fraction or an improper fraction. If it is a proper fraction, display the number. If not, reduce it to a mixed fraction or to an integer (see sample output below).
Answer:
fraction = input("enter fraction x/y: ")
if len(fraction) == 3:
if fraction[1] == "/":
try:
num = int(fraction[0])
den = int(fraction[2])
if num < den:
print(f"{num}/{den} is a proper fraction")
else:
if num% den == 0
print(f"{num}/{den} is an improper fraction and can be reduced to {num/den}")
else:
print(f"{num}/{den} is an improper fraction and can be reduced to {num//den} + {num - (den * (num//den))}/{den}")
except ValueError:
print("numerator and denominator must be integer numbers")
Explanation:
The try and except statement of the python program is used to catch value error of the input fraction of values that are not number digits. The program converts the numerator and denominator string values to integers and checks for the larger value of both.
The program prints the fraction as a proper fraction if the numerator is lesser and improper if not.
The Clean Air Act Amendments of 1990 prohibit service-related releases of all ____________. A) GasB) OzoneC) MercuryD) Refrigerants
Answer:
D. Refrigerants
Explanation:
In the United States of America, the agency which was established by US Congress and saddled with the responsibility of overseeing all aspects of pollution, environmental clean up, pesticide use, contamination, and hazardous waste spills is the Environmental Protection Agency (EPA). Also, EPA research solutions, policy development, and enforcement of regulations through the resource Conservation and Recovery Act .
The Clean Air Act Amendments of 1990 prohibit service-related releases of all refrigerants such as R-12 and R-134a. This ban became effective on the 1st of January, 1993.
Refrigerants refers to any chemical substance that undergoes a phase change (liquid and gas) so as to enable the cooling and freezing of materials. They are typically used in air conditioners, refrigerators, water dispensers, etc.

Explanation:
Write a function called is_present that takes in two parameters: an integer and a list of integers (NOTE that the first parameter should be the integer and the second parameter should be the list) and returns True if the integer is present in the list and returns False if the integer is not present in the list. You can pick everything about the parameter name and how you write the body of the function, but it must be called is_present. The code challenge will call your is_present function with many inputs and check that it behaves correctly on all of them. The code to read in the inputs from the user and to print the output is already written in the backend. Your task is to only write the is_present function.
Answer:
The function in python is as follows
def is_present(num,list):
stat = False
if num in list:
stat = True
return bool(stat)
Explanation:
This defines the function
def is_present(num,list):
This initializes a boolean variable to false
stat = False
If the integer number is present in the list
if num in list:
This boolean variable is updated to true
stat = True
This returns true or false
return bool(stat)

You've created a new programming language, and now you've decided to add hashmap support to it. Actually you are quite disappointed that in common programming languages it's impossible to add a number to all hashmap keys, or all its values. So you've decided to take matters into your own hands and implement your own hashmap in your new language that has the following operations:
insert x y - insert an object with key x and value y.
get x - return the value of an object with key x.
addToKey x - add x to all keys in map.
addToValue y - add y to all values in map.
To test out your new hashmap, you have a list of queries in the form of two arrays: queryTypes contains the names of the methods to be called (eg: insert, get, etc), and queries contains the arguments for those methods (the x and y values).
Your task is to implement this hashmap, apply the given queries, and to find the sum of all the results for get operations.
Example
For queryType = ["insert", "insert", "addToValue", "addToKey", "get"] and query = [[1, 2], [2, 3], [2], [1], [3]], the output should be hashMap(queryType, query) = 5.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 2, 2: 3}
3 query: {1: 4, 2: 5}
4 query: {2: 4, 3: 5}
5 query: answer is 5
The result of the last get query for 3 is 5 in the resulting hashmap.
For queryType = ["insert", "addToValue", "get", "insert", "addToKey", "addToValue", "get"] and query = [[1, 2], [2], [1], [2, 3], [1], [-1], [3]], the output should be hashMap(queryType, query) = 6.
The hashmap looks like this after each query:
1 query: {1: 2}
2 query: {1: 4}
3 query: answer is 4
4 query: {1: 4, 2: 3}
5 query: {2: 4, 3: 3}
6 query: {2: 3, 3: 2}
7 query: answer is 2
The sum of the results for all the get queries is equal to 4 + 2 = 6.

magine that you are designing an application where you need to perform the operations Insert, DeleteMaximum, and Delete Minimum. For this application, the cost of inserting is not important, because itcan be done off-line prior to startup of the time-critical section, but the performance of the two deletionoperations are critical. Repeated deletions of either kind must work as fast as possible. Suggest a datastructure that can support this application, and justify your suggestion. What is the time complexity foreach of the three key operations
Answer:
Use the stack data structure with both best-case and worst-case time complexity of O(1) for insertion and deletion of elements.
Explanation:
The stack data structure is used in programs to hold data for which the last data in the stack is always popped out first when retrieving the data sequentially, that it, first-in, last-out.
The elements in the stack are located in an index location, which means that they can be retrieved directly by choice with constant time complexity of 1 or O(1) for best and worst-case.
So inserting, and deleting the minimum and maximum elements in the stack data structure executes at a speed of the constant 1 (big-O notation, O(1) ).

Explanation:
#Answer is written in Python programming language
#Get inputs
radius = float(input("Enter radius in inches: "))
height = float(input("Enter height in feet: "))
#Convert height in feet to height in inches
height_in_inches = height * 12
#calculate volume in cubic inches
volume = 3.14 * (radius**2) * height_to_inches
#convert volume in cubic inches to volume in gallons
volume_in_gallons = volume * 0.00433
#output result
