Course information (derived classes) define a course base class with attributes number and title. define a print_info() method that displays the course number and title. also define a derived class offeredcourse with the additional attributes instructor_name, term, and class_time. ex: if the input is: ece287digital systems designece387embedded systems designmark pattersonfall 2018wf: 2-3: 30 pm the output is: course information: course number: ece287course title: digital systems designcourse information: course number: ece387course title: embedded systems designinstructor name: mark pattersonterm: fall 2018class time: wf: 2-3: 30 pm

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
