Run the following program and take a screenshot of the result. Explain the relationship between the created processes. (Hint: if we draw an arrow that points from a process to its child process, what shape can we get?) #include #include #include int main (int argc, char argv[1) pid-t childpid = 0; int i, nbrofProcesses; if (argc2) /* Check for valid number of command-line arguments fprintf(stderr, "Usage: %s \n", argv [0]); return 1i /Convert character string to integer / nbrotProcesses = atoi (argv/ 1)) ; for i-l; i

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
