Answer:
The correct answer is True.
Explanation:
The electromagnetic spectrum consists of various waves. The Radio waves are categorized to be at the low-frequency end of this spectrum.
Radio Waves have multiple communication uses. Some of them are television and radio broadcasting, communications, and satellite transmissions.
Radio waves are not harmful to biotic life when absorbed by living matter and their transmission is unimpeded by air. Their transmission can also be absorbed, deflected, reflected, refracted, or diffracted by air molecules and the earth's surface.

Write the field for the table "BOOK" with its field type and also write the primary key for the table.
Answer:
Fields are the components that provide structure for a table. Fields in a table store the same category of data in the same data type. For example, if you have a NAME field in a table of customers, the entries for this field are all customer names and are stored as text.
A primary key is a field or set of fields with values that are unique throughout a table. Values of the key can be used to refer to entire records, because each record has a different value for the key. Each table can only have one
primary key.
The primary key of this table is the ISBN, which uniquely identifies a book. The title column relates to the book; this is the title of the book. Each row of this table is about one book.

Convert the algebraic expression below to C++ statement Do not use the pow function. Ans = 5x^2 + 15k + y^-2
Answer:
The C++ statement for the given algebraic expression 5x^2 + 15k + y^-2 is ( ( 5 * ( x * x ) ) + ( 15 * k ) + ( 1 / ( y * y ) ).
Explanation:
To convert the given algebraic expression 5x^2 + 15k + y^-2 into the C++ statement without using the pow function is:
In the given algebraic expression, there are three expressions combined using the + operator.
The first algebraic expression is 5x^2.
Here, x has a power of 2, and 5 is multiplied by the result of x^2. x having the power of 2 means x is multiplied itself twice. The C++ statement for this algebraic expression is (5 * ( x * x)).
The second algebraic expression is 15k.
Here, 15 is multiplied by k. The C++ statement for this algebraic expression is (15 * k).
The third algebraic expression is y^-2.
Here, x has a power of -2. it means [tex]1/y^{2}[/tex]. The C++ statement for this algebraic expression is (1/ (y * y).
The combination of all the three C++ statement is (5 * ( x * x)) + (15 * k) + (1/ (y * y).

A company has recently adopted a hybrid cloud architecture and is planning to migrate a database hosted on-premises to AWS. The database currently has over 50 TB of consumer data, handles highly transactional (OLTP) workloads, and is expected to grow. The Solutions Architect should ensure that the database is ACID-compliant and can handle complex queries of the application.
Which type of database service should the Architect use?
A. Amazon Redshift
B. Amazon DynamoDB
C. Amazon Aurora
D. Amazon RDS
Answer: Amazon Aurora
Explanation:
Amazon Aurora is a fully managed service which is vital in saving time through the automation of time consuming tasks like recovery, backup, provisioning, patching, repair, and failure detection.
Amazon Aurora also allows the encryption of databases through the use of keys that are managed through the AWS Key Management Service. Therefore, based on the information given the question, type of database service that the Architect should use is Amazon Aurora.

A regional bank implemented an automated solution to streamline their operations for receiving and processing checks/cheques
A regional bank implemented an automated solution to streamline its operations for receiving and processing checks/cheques. They would like to further enhance the solution to recognize signs of potential check fraud and alert their security teams accordingly.
Which technology could be combined with the current solution to do this?
Answer:
Machine learning
Explanation:
The technology that could be used in combining with the current solution to do this is known as MACHINE LEARNING
Given that Machine Learning is a form of Artificial Intelligence, which is designed to possess the ability to act or mimic human beings and their functional characteristics to solve human problems.
Hence, because the regional bank prefers to streamline their processes of receiving and carrying out checks/cheques while also enhancing the solution to recognize signs of potential check fraud, then the technology they could use is called MACHINE LEARNING.
This is because Machine Learning will operate like humans to solve human problems efficiently.

Two devices used by the supermarket point-of-sale (POS) terminal are a bar code reader and a keyboard. Name two other input/output devices used at the POS and give a use for each device.
Answer:
1. Receipt printer
Use of receipt printer:
i. They are used to print customer transaction receipts for proof.
2. Touch screen monitor
Use of touch screen monitor:
i. Allow record of when, where, price, and other important information about the sale conducted.
Explanation:
A Point of sale (POS) terminal takes record of transactions at the point where a product is purchased or a service is rendered. A barcode reader is a price scanner that is an input device used in a point-of-sale (POS) terminal. The keyboard is also an input device. The receipt printer is an output device since it converts information into a readable format. While only a touch screen monitor among the other devices mentioned above is an input and output device, because of its touch panel and its ability to display information.
is solar energy reliable and powerful enough to be used in home or business
Answer:
It all depends on what you are prepared to spend and what sort of system you install. I have both grid tie and stand alone systems installed at my home, and both work really well, although we initially had some inverter problems with the grid tie system until we decided to only use top shelf gear.
We have 6.6 kW grid tie system on the roof of the house which supplies around 3 times our requirements, and a 1.5 kW stand alone system that supplies the backyard workshop and pool pump. The grid tie system cost around $6500 to install, and the small stand alone system cost $4500 although this was designed and built by myself, so a purchased system may well be more (batteries are still expensive, but this price is coming down).
In the current configuration (top tier panels, Fronius grid tie inverter and Victron stand alone inverter and charge regulator), we have had no failures in several years, and power bills are something that happen to other people.
My advice is look at what your requirements are, then double that when you spec out your system and don’t go for the cheapest price. Buy your components based on the quality and reputation of the manufacturer, it will be expensive, but you will save money in the long run. A good manufacturer will guarantee their products for at least 12 years and you should expect to get at least 20 years of life out of them.
Explanation:
Solar energy is more than enough for any business or home, but if you want to know if it is cost effective, you need to run the numbers. It does have to be grid-tied though to provide electricity at night or when cloudy for multiple days. In most cases, batteries are not cost-effective at this time.
