Why would you want to hyperlink objects into your own Google Slides presentation? (Select all that apply.) Select All Correct Responses For extending the learning experience for students. To make sure the presentation is linear So students can use the Slides for review and can go to additional resources outside of the presentation. To make the presentation more graphically appealing
The correct answers are A. For extending the learning experience for students. C. So students can use the Slides for review and can go to additional resources outside of the presentation. D. To make the presentation more graphically appealing
Explanation:
The use of hyperlink objects in presentations means objects such as images, texts, or icons are associated with links or websites students can easily access by clicking on the specific image or element. This might be used in educational contexts to allow students to have a complete learning experience by providing alternative and external sources outside the presentation. For example, if the topic is space hyperlinks to NASA website can be included. This means, hyperlink objects extend learning experiences and provide additional resources (Option A and D).
Besides this, this resource can make a presentation more appealing as links to images, videos, and other visually interesting resources can be included (Option D). However, it also breaks the linearity of the presentation as students will need to move to other websites as they go through the presentation.

Consider the following code snippet: int score = 0; double price = 100; if (score > 0 && price < 200 && price / score > 10) { System.out.println("buy"); } Which of the following statements is true on the basis of this code snippet? The output is buy. The code snippet compiles and runs, but there is no output. The code snippet doesn't compile. The code snippet causes a divide-by-zero error.
Answer:
The code snippet compiles and runs, but there is no output.
Explanation:
The condition is
score > 0 && price < 200 && price / score > 10score = 0
price = 100
[(0) > 0] and [(100) < 200] and [100)/(0) > 10]
false and ........
Since the first condition is false, the program will not validate the other conditions because the conditional "and" is false when at least one of the conditions is false
If the primary voltage of a transformer is 230V and the primary coil is 80. Calculate the secondary voltage when the secondary turn is 160. *Ans 460 volts*
Answer:
[tex]V_{out} = 460[/tex]
Explanation:
From your question, you already posted the answer
However, I'll give the steps to get the answer
Given
[tex]Primary\ Voltage = 230V[/tex]
[tex]Primary\ Coil = 80[/tex]
[tex]Secondary\ Coil = 160[/tex]
Required
Secondary Voltage
The relationship between the primary voltage, secondary voltage, turns of primary coil and secondary coil is as follows;
[tex]\frac{V_{out}}{V_{in}} = \frac{N_{s}}{N_{p}}[/tex]
Where
[tex]V_{in} = Primary\ Voltage = 230V[/tex]
[tex]V_{out} = Secondary\ Voltage = ??[/tex]
[tex]N_{p} = Primary\ Coil = 80[/tex]
[tex]N_{s} = Secondary\ Coil = 160[/tex]
Substitute these values in the formula above;
[tex]\frac{V_{out}}{V_{in}} = \frac{N_{s}}{N_{p}}[/tex]
becomes
[tex]\frac{V_{out}}{230} = \frac{160}{80}[/tex]
[tex]\frac{V_{out}}{230} = 2[/tex]
Multiply both sides by 230
[tex]230 * \frac{V_{out}}{230} = 2 * 230[/tex]
[tex]V_{out} = 2 * 230[/tex]
[tex]V_{out} = 460[/tex]
Hence, the secondary voltage is 460 Volts
Answer:
460 volts

An array of int named a that contains exactly five elements has already been declared and initialized. In addition, an int variable j has also been declared and initialized to a value somewhere between 0 and 3. Write a single statement that assigns a new
Answer:
a[j] = 2 * a[j+1];
Explanation:
The complete statement is to Write a single statement that assigns a new value to the element of the array indexed by j. This new value should be equal to twice the value stored in the next element of the array.
So lets say a is an array of type int which is already declared and initialized.
int a[] = {};
declare an int variable j as int j;
The element of array a indexed by j can be represented as a[j] This means the j-th index of array a
The value to be assigned to a[j] is 2 * a[j+1]; with an assignment operator "= " between a[j] and 2 * a[j+1]; in order to assign 2 * a[j+1]; to a[j]
According to the requirement this new value should be twice the value stored in next element of array. The next element of array is represented by a[j+1] which means j+1 index of array a. This means the element at j+1 index that comes after the element at j-th index a[j].
Value should be twice the value stored in next element of array means multiply the 2 with the next element of array i.e. a[j+1]
Now assign this new value 2 * a[j+1]; to a[j].

Booting
Explanation:
Booting is the start up sequence a computer conducts when it is being turned on. The booting is done by the operating system. The booting process is usually started when a hardware on the computer is pressed or by a software command. For a windows computer, the BIOS is used to start the booting sequence. These boot sequence is called boot order or BIOS boot sequence.
A user is having a difficult time printing certain types of documents to her laser printer. When she sends complex, mult-page, multi-color PDF files to the printer, it refuses to print. What is most likely the solution
Answer:
Add RAM to the printer
Explanation:
Adding RAM to the printers gives the following advantages:
printer prints the documents faster with reduced print time. printer prints complex multi page, multi-color documents especially PDF files.Print server sends the job according to the capacity of the printer so when the RAM is added the print server can send more jobs and the printing process becomes faster and printer will not refuse to print large documents. As a result printer can accept more print jobs.It is also beneficial when the documents or files to be printed are of high resolution or are heavy files.What is the features of Mark 1
Answer:
Okay:
Mark I was enourmous in size, measuring 8 feet high, 51 feet long and three feet deep. It weighed 5 tons, used 530 miles of wire and 730,000 separate parts. The operation of these parts was powered and synchronized by a long horizontal rotating shaft. A four horsepower engine drives the mechanical parts.
Harvard Mark I, an early protocomputer, built during World War II in the United States. While Vannevar Bush was working on analog computing at the Massachusetts Institute of Technology (MIT), across town Harvard University professor Howard Aiken was working with digital devices for calculation. He had begun to realize in hardware something like the 19th-century English inventor Charles Babbage’s Analytical Engine, which he had read about. Starting in 1937, Aiken laid out detailed plans for a series of four calculating machines of increasing sophistication, based on different technologies, from the largely mechanical Mark I to the electronic Mark IV.

write down a description of how a magnetic had drive works
Answer:
This is how a magnetic hard drive works
Explanation:
The hard drive contains a spinning platter with a thin magnetic coating. A "head" moves over the platter, writing 0's and 1's as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0's and 1's.

What visual practice provides more information about logical relations when creating an ERD
Answer:
Logical Data Model
Explanation:
An Entity Relationship Diagram (ERD) is a model or a diagram designed to reveal the relationship between various entities such as people, places, objects, and so on within an institution. Entity relationship diagram is also known as Entity relationship model. This model is used to design relational database by various sectors such as education, engineering, business, etc.
ERD is designed using conceptual data model, logical data model, and physical data model.
The visual practice or model that gives more insight into the logical relations among the entity is the logical data model.
The logical data model is used to illustrate more detailed operational and relational data among the entities. It is more detailed than the conceptual data.
So, the correct answer is logical data model.
What are limitations of AI
Explanation:
Limitations of artificial intelligence. One of the main barriers to implementing AI is the availability of data. Data is often siloed or inconsistent and of poor quality, all of which presents challenges for businesses looking to create value from AI at scale.
Answer:
Risks and limitations of artificial intelligence in business
Businesses are increasingly looking for ways to put artificial intelligence (AI) technologies to work to improve their productivity, profitability and business results.
However, while there are many business benefits of artificial intelligence, there are also certain barriers and disadvantages to keep in mind.
Limitations of artificial intelligence
One of the main barriers to implementing AI is the availability of data. Data is often siloed or inconsistent and of poor quality, all of which presents challenges for businesses looking to create value from AI at scale. To overcome this, you should have a clear strategy from the outset for sourcing the data that your AI will require.
Another key roadblock to AI adoption is the skills shortage and the availability of technical staff with the experience and training necessary to effectively deploy and operate AI solutions. Research suggests experienced data scientists are in short supply as are other specialised data professionals skilled in machine learning, training good models, etc.
Cost is another key consideration with procuring AI technologies. Businesses that lack in-house skills or are unfamiliar with AI often have to outsource, which is where challenges of cost and maintenance come in. Due to their complex nature, smart technologies can be expensive and you can incur further costs for repair and ongoing maintenance. The computational cost for training data models etc can also be an additional expense.
Software programs need regular upgrading to adapt to the changing business environment and, in case of breakdown, present a risk of losing code or important data. Restoring this is often time-consuming and costly. However, this risk is no greater with AI than with other software development. Provided that the system is designed well and that those procuring AI understand their requirements and options, these risks can be mitigated.
See also Industry 4.0 challenges and risks.
Other AI limitations relate to:
implementation times, which may be lengthy depending on what you are trying to implement
integration challenges and lack of understanding of the state-of-the-art systems
usability and interoperability with other systems and platforms
If you're deciding whether to take on AI-driven technology, you should also consider:
customer privacy
potential lack of transparency
technological complexity
If you're considering writing a tender document to procure AI, you can seek help from the Northern Ireland Artificial Intelligence Collaborative Network(link is external).
AI and ethical concerns
With the rapid development of AI, a number of ethical issues have cropped up. These include:
the potential of automation technology to give rise to job losses
the need to redeploy or retrain employees to keep them in jobs
fair distribution of wealth created by machines
the effect of machine interaction on human behaviour and attention
the need to address algorithmic bias originating from human bias in the data
the security of AI systems (eg autonomous weapons) that can potentially cause damage
the need to mitigate against unintended consequences, as smart machines are thought to learn and develop independently
While you can't ignore these risks, it is worth keeping in mind that advances in AI can - for the most part - create better business and better lives for everyone. If implemented responsibly, artificial intelligence has immense and beneficial potential.
Draw a truth table & logic circuit corresponding to the following logic statement
X = 1 if ( ( M is 1 OR N is 1 ) AND ( M is 1 AND N is 1 ) ) OR ( O is NOT 1 )
Answer:
The truth table, as well as the logic circuit of the given statement, is attached below.
Explanation:
Logical gates seem to be the essential building blocks of just about any computerized signal. It becomes a digital device with one or even more inputs and therefore only single output. The arrangement among outputs and inputs would be focused on this kind of logic. Upon that basis, logic gates were already called as AND, NOT, OR gate, etc.

int var;
var = -1;
var = var - 1;
var = var - var;
Answer:
The value of var is 0
Explanation:
Given:
The code snippet above
Required
Find the value of var after program execution
This line declares var as type integer
int var;
This line initializes var to -1
var = -1;
This line subtracts 1 from var; var - 1 = -1 -1 = -2
var = var - 1;
At this stage the value of var is -2
This line subtracts the value of var from var; i.e. -2 - (-2) = -2 + 2 = 0
var = var - var;
At this stage, the value of var is 0
