Answer:
the new exposure time would be 0.049 seconds
Step-by-step answer:
Given that:
Distance 1 = D1 = 42 inch
Current = 300 mA
Time 1 = T1 = 0.06 seconds
Max voltage = 80 kVp
Distance 2 = D2 = 38 inches
Time 2 = T2 = ?
Inverse square law states that:
The intensity of radiation becomes weaker as it spreads out from the source since the same about of radiation becomes spread over a larger area. The intensity is inversely proportional to the distance from the source.
Mathematically,
I1/ I2 = D1^2/ D2^2 ------------ eq1
Intensity 1 = I1 = Current * time = 300 * 0.06 = 18 mAs
Let Intensity 2 as I2
Putting values in eq1
18/ I2 = (42)^2/(38)^2
By simplifying:
18/ I 2 = 1764/1444
By cross multiplying we get:
1764 * I2 = 25,992
Dividing both sides by 1764 we get:
Intensity 2 = I2 = 14.7 mAs
Now we will find exposure time.
We know that:
Intensity = Current * Time
As Intensity 2 = 14.7 , Current = 300 mA and time is T2
So by putting values:
14.7 = 300 * T2
By simplifying,
T2 = 0.049 seconds
So the new exposure time required would be 0.049

What kind of attack allows for the construction of LDAP statements based on user input statements, which can then be used to access the LDAP database or modify the database's information?
Answer:
LDAP injection
Explanation:
LDAP injection is a kind of assault on a web application where hackers place code in a client input field with the aim of gaining unauthorized access in to the system or retrieve information.
At the point when a web application doesn't satisfactorily sanitize client provided input, hackers might have the option to change the construction of a LDAP statement which will run with similar permissions that executed the command.
Suppose you wish to write a method that returns the sum of the elements in partially filled array. Which is the best choice for a method header? Group of answer choices public int sum() public int sum(int[] values, int currSize) public int sum(int[] values) public int sum(int[] values, int size, int currSize)
Answer:
The Method header to this question is "int sum(int[] values, int currSize)".
Explanation:
According to the question, It is defined that choose the correct option which creates a method header sum and returns the sum of the array element. In given options, we choose option second because in this option method return type is int and use an integer variable that is "currSize" which calculate the sum and return its value and other option are not correct that can be described as:
In the first option, we create a method but we do not pass any parameter so it will not calculate the sum of array elements. In the third option, we create a method but we pass only one parameter that is an array. So, it will not calculate the sum of array elements correctly. In the fourth option, In this method, we pass three parameters that are "values, size and currSize" in which the size parameter not use.That's why the answer to this question is option second which is "int sum(int[] values, int currSize)".

To output the contents of a fully-filled two-dimensional array using pseudocode, write out the elements in the columns within a row, before moving to the next row, using a ________ loop within another.
A. DOWHILE
B. REPEAT UNTIL
C. DO
D. None of the other answers are correct
Answer:
B.
Explanation:
Based on the information provided within the question it can be said that the loop that should be used is a repeat until loop. This is because this loop will continue cycling until a certain condition is met. In this situation, the loop breakout condition would be the output of the final element in the last column and row of the two-dimensional array.
Final answer:
To output the contents of a fully-filled two-dimensional array using pseudocode, you can use a nested FOR loop. The outer loop will iterate over the rows of the array, while the inner loop will iterate over the columns within each row.
Explanation:
To output the contents of a fully-filled two-dimensional array using pseudocode, you can use a nested FOR loop. The outer loop will iterate over the rows of the array, while the inner loop will iterate over the columns within each row. Here's an example:
FOR row = 1 TO number_of_rows
FOR column = 1 TO number_of_columns
OUTPUT array[row][column]
END FOR
END FOR
In this pseudocode, number_of_rows and number_of_columns represent the dimensions of the array. The OUTPUT statement is used to display the value of each element in the array.

Which statement about muzzleloaders is true? All muzzleloaders are rifles. All muzzleloaders have only one barrel. Muzzleloaders are safer and easier to use than modern firearms. Muzzleloaders are early firearms that are loaded from the open end.
Answer:
Muzzleloaders are early firearms that are loaded from the open end
Explanation:
A muzzleloader is any firearm into which the projectile and usually the propellant charge is loaded from the muzzle of the gun.
This is distinct from the more popular modern designs of breech-loading firearms.
Thus, muzzleloaders are early firearms that are loaded from the open end.
Early firearms that loaded with an open end were known as muzzleloaders.
Guns known as muzzleloaders are loaded by placing the bullet and propellant (such as black powder) into the open end of the weapon's barrel. Contrast this with contemporary firearms, which use cartridge-based gunpowder. Prior to the development of breech-loaded firearms, muzzleloaders had a long history and were frequently used. The most prevalent muzzleloaders are the single-barreled models, most often employed for target shooting and hunting. But double-barreled and even multi-barreled muzzleloaders are also available.
Therefore, the correct option is D.

Answer:
distributed
Explanation:
According to my expertise in information technology, it seems that the type of database being described is a distributed database. Like mentioned in the question this is a database that works by saving information in data centers from various locations and information is processed through multiple database node. This allows information to be more secured, faster, and also acts as a fail-safe in case of any malfunction where data may otherwise be lost.
A distributed database allows for data storage across numerous machines globally, synchronized for consistent data, using a database management system to handle the datasets and a relational database management system to manage the data without reorganizing tables.
Explanation:A distributed database makes it possible to store information across millions of machines in hundreds of data centers around the globe, with special time-keeping tools to synchronize the data and ensure the data are always consistent. Such databases utilize a database management system (DBMS) to create, store, maintain, manipulate, and retrieve large datasets distributed over multiple files and locations. Additionally, a relational database management system (RDBMS) is often employed in distributed databases to manage the data efficiently without the need for reorganizing the tables.
Relational databases
are characterized by their use of tables to organize data, which are related through primary and foreign keys. This structure effectively supports operations like updating, expanding, and deleting data, and allows for quick data manipulation and enhanced data accuracy through automated rules. Today's digital databases, supported by advanced DBMS and RDBMS technologies, are central to the Information Age, far surpassing the traditional filing cabinet by enabling the storage of vast amounts of data on networks and the Internet.

OR
NOR
IFTRUE
IFERROR
Answer:
The answer is "IF and IFERROR".
Explanation:
The conditional logic function is used in excel that use to generate a conditional equation. It is normal to use for many tasks to check whether facts are true or false and to make logical distinctions between words.
This function considers IF and IFTRUE as a conditional logic function. and others are not correct that can be defined as:
The NOR and OR is used as a boolean operator functions in excel that return true or false value only.IFTRUE and WHEN is used in programming language. It used as a macro and condition operator.Condition statements are “IF, IFTRUE, IFERROR".
Explanation:
In programming languages “IF <Conditon>’” is used. Normally if condition means, if given condition is true either single statement or multiple statement are executed.
With “IF <Conditon>” has “ELSE” or “ELSEIF <Conditonn>”, Else path execution of “IF <CONDITON>” is false.
Same “ELSEIF <CONDITION>” is executed if “IF CONDITON” is false.
“OR and NOR” is logical operations, “When” is only on sql query mostly.

How are 8-position, 8-contact (8P8C) modular connectors pinned to unshielded twisted-pair (UTP) cable, which is used for connecting computers and broadband modems to a local area network (LAN)?
An unshielded cable are twisted pair is used to connect modem in telecommunication industry to connect computer through telephone cable, Ethernet cables it is called as UTP cables.
Explanation:
These UTP cables are twisted cables where conducted are used in form of single circuit.
These types of UTP cables used to connect modem to establish connection to other networks for internet or connecting to other side computer or desktop or laptops.
UTP cables uses rj-45 or rj-11 or rs232 or rs 499. Normally rs-45 with cat 5e cable is used to connect LAN. Rj-11 is used to connect to modem for dial purpose.
If we use ip networks RJ-45 will do both.
Final answer:
8P8C modular connectors, often called RJ45, are pinned to UTP cables using either T568A or T568B standards, with T568B being the most common in the US for LAN connections. Both cable ends must be pinned identically for proper functionality, and the twisted pair design helps reduce electromagnetic interference.
Explanation:
The 8-position, 8-contact (8P8C) modular connectors, commonly known as RJ45 connectors, are typically pinned to unshielded twisted-pair (UTP) cables according to the T568A or T568B standards. The difference between these two standards is the position of the orange and green wire pairs. The pinning for T568B, the most common standard in the US for connecting computers and broadband modems to a LAN, is as follows:
Pin 1 - White/OrangePin 2 - OrangePin 3 - White/GreenPin 4 - BluePin 5 - White/BluePin 6 - GreenPin 7 - White/BrownPin 8 - BrownIt's important to ensure that both ends of the UTP cable are pinned in the same way to function correctly. The primary purpose of using the 8P8C connector with UTP cable is for data transmission while maintaining the integrity of the signal through the twisted pairs which minimize electromagnetic interference.

In what programming language?
Explanation:
A(n) _____ is someone who uncovers computer weaknesses and reveals them to manufacturers or system owners, without exploiting these vulnerabilities.A. corporate spyB. ethical cyber criminalC. hacktivistD. white hat hackerE. data harvester
Answer: white hat hacker
Explanation:
Like other forms of hacker, white hat hackers also have wide range of knowledge of breaking into systems, overriding firewalls, bypassing security protocols and can also do all other things hackers do. But what differentiates white hat hackers is the motive behind what they do, in that they carry out all this test not for their personal gain but for the benefit of the owners and also with the approval of the owners. Because after carrying out tests on the ways of exploiting the loop holes in the system they reveal it to the manufacturer or system owners for correction.
Write a function called check_nums that takes a list as its parameter, and contains a while loop that only stops once the element of the list is the number 7. What is returned is a list of all of the numbers up until it reaches 7.
Answer:
Following are the program in the Python Programming Language:
def check_nums(length): #define function
my_lst=[] #set list type variable
n=0 #set integer type variable
while(length[n] != 7): #set the while loop
my_lst.append(length[n]) #append liat in my_lst
n+=1 #increament in n
if(len(length)==n): #set if condition
break #break the loop
return my_lst #return the list
l=[4,6,2,55,16,7,81] #set list variable and assign list init
print(check_nums(l)) #call and print the function
Output:
[4, 6, 2, 55, 16]
Explanation:
Here, we define a function "check_nums()" and pass an argument in its parentheses inside the function,
we set list data type variable "my_lst" and integer type variable "n"we set while loop and pass the condition is the variable "length[n]" is not equal to the 7 then, the value of "length[n] " is appends to the variable "my_lst" and increment in the variable "n" by 1.we set if condition and check when the length of the variable "length" is equal to the variable "n" then, break the loop and return the value of "my_lst".Finally, set the list type variable "l" and assign the list of numeric value in it then, call and print the function "check_nums"
In this exercise, using the knowledge of computational language in python, we have that this code will be written as:
The code is in the attached image.
We can write the python as:
def check_nums(length):
my_lst=[]
n=0
while(length[n] != 7):
my_lst.append(length[n])
n+=1
if(len(length)==n):
break
return my_lst
l=[4,6,2,55,16,7,81]
print(check_nums(l))
