The program should read in the students’ scores two quizzes, midterm and final and display the student’s records, which consists of all the above +final number and final letter grade. overall numeric grade is calculated as 50%-final exam, 25%-midterm and two quizzes together count for 25%. for letter grade 90-100 is a 80-89 is b 70-79 is c 60-69 is d and any grade < 60 is f grade when taking input, quiz grades are out of 10 points and midterm and final are out of 100 points. the driver program hw5 which should instantiate the student object and use the input method to take user input and output method to display records.

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
