Do exercises as follows:

a. Enter a whole number from keyboard, a while loop should calculate a sum of all numbers from one to that number that you entered
b. Enter a numeric score - grade of a test, your program should print a corresponding letter grade that matches the score.

For example, if you enter 89.3, the program should display "B", and if you enter 95.7, then the program displays "A"

Explanation:

The following Java code creates the MonetaryCoin class that extends the Coin class. It then creates three variables representing the MonetaryCoin object which are its value, weight, and coinYear. These are all passed as arguments to the constructor and saved as instance variables.

public class MonetaryCoin extends Coin {

   int value;

   float weight;

   int coinYear;

   public void MonetaryCoin(int value, float weight, int coinYear) {

       this.value = value;

       this.weight = weight;

       this.coinYear = coinYear;

   }

}

Answer:

The correction is as follows:

n = int(input("Please [tex]enter\ a[/tex] [tex]number\ between\ 1[/tex] and 100: "))

if n < 1 or n > 100:

   print("You [tex]have\ not[/tex] entered a [tex]number\ between\ 1[/tex] and 100.")

elif n % 2 == 0:

   print (n, "is even")

else:

   print (n, "is odd")

Power amplifier stages in a real circuit. Circuit diagram of a three stage practical audio power amplifier is shown in the figure below. Small signal transistor Q1 and its associated components form the voltage amplification stage.

Answer:

Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.

p {

background-color: rgb(255, 0, 0);

}

h1 {

background-color: rgb(0, 255, 0);

}

ol {

background-color: rgb(97,51,47);

}

</style>

Explanation:

Put this at the top of your code. It should target the paragraph tag, the header h1 tag, and the Ordered List (OL) tag individually and set their background colors respectively.
