- (Electrical eng.) a. The voltage gain of an amplifier is given by this formula: voltagegain=[275 23 2 +0.5 f 2 ]n f is the frequency in Hz. n is the number of stages in the amplifier. Using this formula, write, compile, and run a C++ program to determine the value of the voltage gain for a four-stage amplifier operating at a frequency of 120 Hz. Your program should produce the following display: At a frequency of xxxxx hertz, the voltage gain is yyyyy Your program should replace xxxxx with the frequency and yyyyy with the voltage gain. b. Manually check the value your program produces. After verifying that your program is working correctly, modify it to determine the voltage gain of a 12-stage amplifier operating at a frequency of 9500 Hz.arrow_forward(b) The following equations are used to calculate the voltage and power of a load in an electric circuit: Voltage of a load, V = IR Power of a load, P = 1²R (i) Draw a flowchart of a program which allows user to input the current (I) and resistance (R) of a load. The program is required to provide selections for the user to calculate either the voltage (V) or power (P) of the load. The program should also output the message "Invalid Selection" if the user makes invalid choice. (ii) Based on the flowchart above, write a complete program in C.arrow_forward: Practical questiod 1. Write a C program for Arduino thar controls a set of two traffic lights A & B at a crossmadk. Assume that: When the traffic lighus (A) are green or amber, the traffic lights (B) are red. • When the traffic lights (B) are green or amber, the raffic lights (A) are red. Green lights must stay on for 15 seconds, amber lights for 5 seconds and red lights for 20 seconds. 2. Sketch the circuit diagram to wire the Arduina to the two traffic lights.

- Problem 4 - GGiven two points A(-4, –5) and B(4, 1) in XY coordinate system. 4a. Write Python code to calculate the distance between points A and B. 4b. Suppose that the line equation passing through points A and B is y = mx + b, where m is the slope and b is the y-intercept. Write the code to find the slope and the y-intercept of the line. 4c. Write a code to plot the graph of the line equation y = mx + b from part (4b) on the interval -4 < x < 4. Provide appropiate labels for both axes.arrow_forward(Geometry: area of a regular polygon) A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is n x s? Area 4 X tan Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area. Here is a sample run:arrow_forward(python) Speed of Sound is a constant 343 m/s Create a function that will return the Frequency Heard based on the above equation. The function should accept the following parameters: speed of sound, velocity of receiver, velocity of source and frequency of source. Make sure to prompt the user for the input data and call the function. Example Values/Results: Frequency of Source: 935 HzVelocity of receiver: 24 m/sVelocity of source 43 m/sHeard frequency is 888.977 Hzarrow_forward
- (C PROGRAMMING ONLY) 1. Leap Year Detectorby CodeChum Admin Let’s try to find out whether a year has 365 or 366 days. To do this, we need to create a leap year detector! Conditions for a leap year: 1.) year must be divisible by 4 and not divisible by 100 2.) If year is divisible by 100, it must be divisible by 400 for it to be a leap year. Instructions: You are provided with the isLeapYear() function which is already declared and defined for you.Your task is to ask the user for a year and then call the isLeapYear function to check whether the year is a leap year or not.Input 1. Year to be checked Output If a certain year is a leap year, print "<INSERT_YEAR_HERE> is a leap year"Otherwise, print "<INSERT_YEAR_HERE> is not a leap year" Enter year: 20202020 is a leap yeararrow_forward( C PROGRAMMING ONLY) 5. Simplicity is Beautyby CodeChum Admin In life, simplicity is beauty. Let's try creating something so simple. Let's create a function that accepts the address of an integer and prints n number of asterisks out of it. For example, if the value of the address passed is 5, then the output would be five asterisks in one line. Instructions: In the code editor, you are provided with a main() function that asks the user for an integer and passes the address of this integer to a function call of the simple() function.This simple() function hasn't been implemented yet so your task is just that, to implement it. This has the following description:Return type - voidName - simpleParameter - address of an integerDescription - prints a line of asterisksDO NOT EDIT THE MAIN FUNCTIONInput 1. An integer Output Enter·n:·5*****arrow_forwardProblem 4. (Regular Expressions-using Python re or Java regex) Write a regular expression for the following word patterns: 1. Word starts with a 'q'. Word has 'th'. 2. 3. Word has an 'q' or a 'Q'. 4. Word starts with an 'q' or an 'Q'. 5. Word has both 'o' and 'u' in it. 6. Word does not have an 'a'arrow_forward
- (PYTHON) Write a program with a function that takes a string; if the length of a string is even, the functionshould add an asterisk at the beginning of a string; else, the function should add asterisks at the end ofa string. The function, then, capitalizes all letters and returns the new string The program should let the user enter a string and pass it to the function.arrow_forwardCreate code for this. (C language only)arrow_forward(Prism Program) Write a program that can calculate the value of the surface area and volume of a Prism. The surface area of a rectangular prism is the total area of all six faces. When you have a cube, finding the area of one face allows you to find the total surface area of the solid very quickly, since it will be six times the area of one face. A = 2(width x length) + 2(length x height) + 2(height x width) Volume is the amount of 3-dimensional space an object occupies. Volume is measured in cubic units. To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism. Volume of rectangular prism = length x width x height The input and Output of your program is as follows: Prism Mania! Prism Result!
