(Hydraulics) a. Write, compile, and run a C++ program to calculate the horizontal force exerted on the T-connector pipe shown in Figure 2.16 when the mass flow rate is 1.5 kg/s, and the fluid’s velocity entering the T-connector is 3 m/s. The formula for determining this force is as follows: Fh=MfvFhisthehorizontalforce(N).Mfisthemassflowrate( kg/s).visthevelocity( m/s)ofthefluidenteringthepipe. Your program should produce the following display (replacing the xxxx with the actual force value your program calculates): The horizontal force, in Newtons, is xxxx b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to calculate the force exerted when the mass flow rate is 2.3 kg/s, and the velocity of the fluid entering the pipe is 4.25 m/s.
(General math) If a 20-foot ladder is placed on the side of a building at an 85-degree angle, as shown in Figure 3.11, the height at which the ladder touches the building can be calculated as height=20sin85. Calculate this height by hand, and then write, compile, and run a C++ program that determines and displays the value of the height. After verifying that your program works correctly, use it to determine the height of a 25-foot ladder placed at an angle of 85 degrees.
(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.
Numerical analysis) Given a number, n, and an approximation for its square root, a closer approximation of the actual square root can be found by using this formula: newapproximation=(n/previousapproximation)+previousapproximation2 Using this information, write a C++ program that prompts the user for a number and an initial guess at its square root. Using this input data, your program should calculate an approximation of the square root that’s accurate to 0.00001. (Hint: Stop the loop when the difference between the two approximations is less than 0.00001.)

Use C++ programming language Write a program , that finds solution (roots) of quadratic equation, allow user to input as much as function they need , terminate program , when user inputted N = No. You need to test if function has two real solution, one real solution or imaginary solution. You must use functions to find roots.
(Electrical eng.) The amplification of electronic circuits is measured in units of decibels, which is calculated as the following: 10LOG(Po/Pi) Po is the power of the output signal, and Pi is the power of the input signal. Using this formula, write, compile, and run a C++ program to calculate and display the decibel amplification, in which the output power is 50 times the input power. Verify your program’s result by doing a hand calculation. After verifying that your program is working correctly, use it to determine the amplification of a circuit, where output power is 4.639 watts and input power is 1 watt.
