Answer:

A. simple to construct and easy to repair

Explanation:

A dynamic microphone works on the principle of electromagnetic principle. A diaphragm is attached to a coil of wire which helps in producing sound. Responding to the sound waves, the coil of the wire is vibrated by the diaphragm.  A magnetic field is created by the magnet which is present inside the coil of wire. The electrical signal is generated in response to the motion of the coil. The speed of the motion produces the amount of the current.

Since the construction of a dynamic microphone is easier as compared to any other microphone, John is likely to opt to build one.

One lap around a standard high-school running track is exactly 0.25 miles. Write a program that takes a number of miles as input
salantis [7]

Answer:

import java.util.Scanner;

public class Miles {

public static void main(String[] args) {

   //initialization

       double Number_Miles;

       //print the message

       System.out.print("Enter the number of miles: ");

       Scanner scn1 = new Scanner(System.in);

       

       Number_Miles = scn1.nextDouble();  //read the input from user

       //calculate the laps

       double yourValue = Number_Miles/0.25;

       //display the output on the screen

       System.out.printf("%.2f", yourValue);

     

}

}  

Explanation:

First import the library Scanner than create the class and define the main function. In the main function, declare the variables.

print the message on the screen and then store the value enter by the user into the variable.

Scanner is a class that is used for reading the output. So, we make the object of the class Scanner and then object call the function nextDouble() which reads the input and store in the variable.

After that, calculate the number of laps by dividing the number of miles with the given one lap running track value (0.25 miles).

Number\,of\,laps = \frac{Number\,of\,miles}{0.25}

the output is stored in the variable.

After that, print the value on the screen with 2 digits after the decimal point.

we can use "%.2f" in the printing function in java.

like System.out.printf("%.2f", output);

kherson [118]

Answer:

// here is code in c.

#include <stdio.h>

// main function

int main()

{

// variable to store year

int year;

printf("enter year:");

// read the year

scanf("%d",&year);

// if year>=2101

if(year>=2101)

{

printf("Distant future");

}

//if year in 2001-2100

else if(year>=2001&&year<=2100)

{

   printf("21st century");

}

//if year in 19011-2000

else if(year>=1901&&year<=2000)

{

  printf("20th century");

}

// if year<=1900

else if(year<=1900)

{

  printf("Long ago");  

}

return 0;

}

Explanation:

Read the year from user.After this, check if year is greater or equal to 2101 then print "Distant future".If year is in between 2001-2100 then print "21st century".If year is in between 1901-2000 then print "20th century".Else if year is less or equal to 1900 then print "Long ago".

Output:

enter year:2018
