Answer:

A)Area = 200cm^{2}

B) Pressure = 0.115 N/cm^{2}

Explanation:

Assuming that the brick is flat on the floor with its largest face towards the floor and not on its side, then we can calculate the area of that face by multiplying the length by the width like so...

Area = length * width

Area = 20cm * 10cm

Area = 200cm^{2}

The formula for calculating pressure is force divided by area. Therefore, since we just finished calculating the area and the force is given to us in the question (23N) we can simply plug in these values and solve for the pressure.

Pressure = Force / Area

Pressure = 23N / 200cm^{2}

Pressure = 0.115 N/cm^{2}

Answer:

Base band : A list of radio frequencies

PRI : The chip that controls the radio frequency waves within a device

PRL: The connection between a mobile device and radio tower

Explanation:

Base-band is the range or band of frequencies. It contains a number of between upper and lower limit of the frequency. For example if the range of transmission of the signal is 2khz to 3khz. The frequencies between this range are called base band.

PRI is the chip that is used to control the different frequencies received at the device. This chip control the radio frequencies that are allowed to the devices. It is the short form of primary rate interface.

PRL is the list named as Preferred Roaming List. It has stored the information of the mobile devices that are connected to the mobile phone. This list is used while communicating between mobile device and tower.

TASK: Write a static method called repeatString that takes as input a String parameter word followed by an int parameter num. It
leva [86]

Answer:

Follows are the method definition to this question:

public static String repeatString(String word, int num)//defining a String method repeatString that takes two parameters

{

   String Val= "";//defining String variable Val

   for(int x = 0;x<num;x++)//defining for loop to calculate number of string

   {

       Val=Val+word;//hold calculated value in Val

   }

   return Val;//return Val value

}

Explanation:

Follows are the full code to this question:

import java.util.*;//import package for user input

public class Main//defining class Main

{

   public static String repeatString(String word, int num)//defining a String method repeatString that takes two parameters

{

   String Val= "";//defining String variable Val

   for(int x = 0;x<num;x++)//defining for loop to calculate number of string

   {

       Val=Val+word;//hold calculated value in Val

   }

   return Val;//return Val value

}

public static void main(String[] ar)//defining main method

{

   int num;//defining integer variable

   String word; //defining String variable

   Scanner on=new Scanner(System.in);//creating Scanner class Object

   System.out.print("Enter numeric value: ");//print message

   num=on.nextInt();//input value

   System.out.print("Enter String value: ");//print message

   word=on.next();//input value

   System.out.print(repeatString(word,num));//call method and print its return value

}

}

Output:

Enter numeric value: 3

Enter String value: data

datadatadata

Description:

Inside the main class,  a static string method "repeatString" is defined that accepts two parameters "word and num", in which one is a string and one is an integer.

Inside the method, the string variable "Val" is defined, which uses the "for" loop to calculate the number of string and store its value in the variable.

In the main class, the above two variables are defined, that uses the Scanner class object for input the value and pass into the method and print its value.

Which is a type of intellectual property law? Select 4 options.
sukhopar [10]

TRADE SECRETS

Trade secrets refer to specific, private information that is important to a business because it gives the business a competitive advantage in its marketplace. If a trade secret is acquired by another company, it could harm the original holder.

Examples of trade secrets include recipes for certain foods and beverages (like Mrs. Fields’ cookies or Sprite), new inventions, software, processes, and even different marketing strategies.  

When a person or business holds a trade secret protection, others cannot copy or steal the idea. In order to establish information as a “trade secret,” and to incur the legal protections associated with trade secrets, businesses must actively behave in a manner that demonstrates their desire to protect the information.

Trade secrets are protected without official registration; however, an owner of a trade secret whose rights are breached–i.e. someone steals their trade secret–may ask a court to ask against that individual and prevent them from using the trade secret.

PATENTS

As defined by the U.S. Patent and Trademark Office (USPTO), a patent is a type of limited-duration protection that can be used to protect inventions (or discoveries) that are new, non-obvious, and useful, such a new process, machine, article of manufacture, or composition of matter.

When a property owner holds a patent, others are prevented, under law, from offering for sale, making, or using the product.

COPYRIGHTS

Copyrights and patents are not the same things, although they are often confused. A copyright is a type of intellectual property protection that protects original works of authorship, which might include literary works, music, art, and more. Today, copyrights also protect computer software and architecture.

Copyright protections are automatic; once you create something, it is yours. However, if your rights under copyright protections are infringed and you wish to file a lawsuit, then registration of your copyright will be necessary.

TRADEMARKS

Finally, the fourth type of intellectual property protection is a trademark protection. Remember, patents are used to protect inventions and discoveries and copyrights are used to protect expressions of ideas and creations, like art and writing.

Trademarks, then, refer to phrases, words, or symbols that distinguish the source of a product or services of one party from another. For example, the Nike symbol–which nearly all could easily recognize and identify–is a type of trademark.

While patents and copyrights can expire, trademark rights come from the use of the trademark, and therefore can be held indefinitely. Like a copyright, registration of a trademark is not required, but registering can offer additional advantages.

program that reads numbers from scanf (keyboard) and then sums them, stopping when 0 has been entered. Construct three versions
Alex17521 [72]

Answer:

Explanation:

I'm going to write three examples in C language:

int main() {

   int n, i, sum = 0;

   printf("Enter the number: ");

   scanf("%d", &n);

   for (i = 1; i <= n; ++i) {

       sum += i;

   }

   printf("Sum = %d", sum);

   return 0;

}

int main() {

   int n, i, sum = 0;

   printf("Enter a number: ");

   scanf("%d", &n);

   i = 1;

   while (i <= n) {

       sum += i;

       ++i;

   }

   printf("Sum = %d", sum);

   return 0;

}

int main() {

   int n, i, sum = 0;

   do {

       printf("Enter a number: ");

       scanf("%d", &n);

   } while (n <= 0);

   for (i = 1; i <= n; ++i) {

       sum += i;

   }

   printf("Sum = %d", sum);

   return 0;

}
