Answer:
C
Explanation:
All Java objects have a toString() method, which is invoked when you try to print an object. The output will be some unreadable binary data because the toString method of the object has not explicitly define in our BankAccount class. To get a readable text as output, the toString method of our BankAccount class need to be over ride.
Adding the below snippet to the BankAccount class will yield a readable output.
@Override
public String toString() {
return nameOfField;
// nameOfField is the name of field defined in BankAccount class which is passed as parameter when creating an instance of the object.
}

A satisfactory radiograph of the abdomen was made at a 42-inch SID using 300 mA, 0.06-second exposure, and 80 kVp. If the distance is changed to 38 inches, what new exposure time would be required?
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

Member function definitions: ______________.a. Always require the binary scope operator (::)b. Require the binary scope operator only when being defined outside of the definition of their class c. Can use the binary scope operator anywhere, but become public functions d. Must use the binary scope operator in their function prototype
Answer:
Option (B) is the correct answer to the following questions.
Explanation:
The following option is correct because the binary scope operator is used to define the global variable only when the local variable has also the same name and we want to use global variable also or we also use scope operate when we do not want to use any function inside the class.
The following option (A) is wrong because we not always required binary scope operator and the option (C) is wrong because we cannot use the scope operator anywhere and the option (d) is already wrong because that binary scope operator would not be used in the function prototype.

This repeated behavior is just like an enemy that attacks a fort.
Optionally, using a key derivation function, the attacker can try to guess the key generally created from the password. This is known as an exhaustive key search.
Historically, it has been observed that computer processing speeds tend to double every two years. Which of the following best describes how technology companies can use this observation for planning purposes?
A. Technology companies can accurately predict the dates when new computing innovations will be available to use.B.Technology companies can plan to double the costs of new products each time advances in processing speed occur.C. Technology companies can set research and development goals based on anticipated processing speeds.D. Technology companies can spend less effort developing new processors because processing speed will always improve at the observed rate.
Answer:
Option C is correct.
Explanation:
This is what is called Moore's law, pronounced by Gordon Moore (Intel's CEO) in 1965. More precisely, it states that transistor count in processors doubles every 2 years. Not always this can translate to more processing power, because usually software can't keep up the pace with the raw power of new processors, and can't take full advantage of its speed.
Moore's law has had a positive effect on the market. Not only to the processor market but more so to the software market. The reason is that even though faster, multi-core processors are out there, the software was written to work with single-thread tech for a long time. Now, developers need to adjust their software to support multi-threading (split the program's functions across all processor cores) to increase performance and take advantage of the speed. This helps developers to create software that is up to the latest technologies and maximize efficiency.
The best choice is C. Technology companies can set research and development goals based on anticipated processing speeds. This approach allows them to align their innovation efforts with expected advancements, ensuring that their products remain competitive and relevant as processing speeds continue to increase.
Choice C is the most viable. By setting research and development goals based on anticipated processing speeds, technology companies can strategically allocate resources and prioritize projects that leverage expected advancements.
This approach enables them to stay ahead in innovation, design products that capitalize on increased processing power, and meet evolving market demands. It also helps in resource planning, allowing for the timely development of competitive products.
However, it's important to note that while the observation of doubling processing speeds every two years provides a general trend, it's not a rigid rule.
Actual progress may vary due to various factors. Thus, companies should adapt their plans accordingly, considering both the observed trend and specific technological developments in their respective fields.
This approach fosters agility and flexibility, essential qualities in the fast-paced technology industry.

Raul is setting up an Excel spreadsheet to track how many hours his employees work each day. For the first worker, he has inserted the formula "=(I3-H3)” into cell J3.
Raul needs to see a number of hours but instead he sees a decimal. He knows the employee worked more than 0.35 hours that day. What should Raul do to make J3 show a number of hours?
A. insert “*24” at the end of the formula
B. reformat J3 as a general number
C. insert “HOURS” after the equal sign in the formula
D. change the order of the cells referenced in the formula
Answer:
The key to solve this number time format in Excel lies in understanding the simple seconds, hour and day calculations together with cell referencing. Cell referencing stands for the cell names where we will be performing our formula.
Explanation:
Numbers in Excel comes in various format. One of the headache from it is Excel often recognize times (x) as a decimal even when we are talking about time or hour. The key to solve this number time format in Excel lies in understanding the simple seconds, hour and day calculations together with cell referencing. Cell referencing stands for the cell names where we will be performing our formula.
The formula that we need to put in to cell J3 should have an idea like this: = (Clocked out - Clocked in) x 24
You can just use a simple formula by applying subtraction operation using from your clocked out / time out to your clocked in / time in. The answer will be the difference of this two times then you should multiple it to 24 which stands for 24 hours in one day.
Another thing, you must use the INT function to make sure that our answers in excel will be rounded off to the nearest integer. We definitely don't want any decimals in any of our cells.
Therefore the formula should look like this in cell J3: = INT((I3-H3) *24).
Almost a similar idea can be applied if we want to solve for the MINUTES between two times. Instead of using 24, we must use 1440 instead. Now, why do we need to use 1440? 1440 stands for the total minutes that we have for a single day. (24 hours * 60 minutes = 1440 minutes)
Therefore the formula should look like this: = ((I3-H3)*1440).
Answer:
its b. reformat J3 as a general number
Explanation:
While working alone at their constant rates computer X can process 240 files in 4 hours, and comp Y 240 files in 8 hrs. If all files processed by these comp. are the same size how long would it take the two comp. working at the same time at their respective constant rates , to process a total of 240 files?
A. 2hrs
B. 2hrs 20 min
C. 2hrs 40 min
D. 6hrs
E. 6hrs 20 min
Answer:
2hrs 40 min
Explanation:
Answer: c) 2hrs 40 min
Explanation:
Rate of working of Computer X is = 240 files/ (4 × 60min)
= 1 file / min
Rate of working of Computer Y is = 240files/ (8×60min)
= 0.5 file/min
The combined rate for computer X & Y is = 1 + 0.5 = 1.5 file/ mins.
Therefore, time taken to process 240 files is = 240/1.5
= 160mins
= 2hrs 40mins

When typing text in a word processing program, you should only press ____ after a short line (like a title), at the end of a paragraph, and to leave a blank line between paragraphs.
Answer:
Enter
Explanation:
In a Microsoft word when we are typing text and want to go to next line just put the cursor at the end of line or line text and then press enter.It will leave a blank line between paragraphs.
In word processing programs like Microsoft Word, the Enter key should only be pressed to end a paragraph, after a title, or to add a blank line. For spacing after a period, one space is the current standard. Indents and line spacing can be adjusted using specific formatting options in the word processor.
Explanation:When typing text in a word processing program, you should only press Enter after a short line (like a title), at the end of a paragraph, and to leave a blank line between paragraphs. This is because most word processing software, including Microsoft Word, automatically wraps text to the next line as you type. To create necessary white space and make your document more readable, adjusting the spacing before and after paragraphs can be done in the Page Layout tab. Additionally, if you require indenting paragraphs, this can be performed using the Paragraph group of the Layout tab, which allows precise control over indents and spacing.
Regarding the space after a period, it is widely accepted now to use a single space after a period at the end of a sentence. This conforms to modern style guides, such as the APA style, which currently requires a single space after a period. Remember that the "rules" for spacing and formatting may change, so it's important to stay up to date with the style guide you are using.
For specialized formatting like creating an ellipsis, remember to include a space between each dot and ensure it does not wrap to the next line. Likewise, if an ellipsis is used at the end of a sentence, it will appear after the period with a space in between.
