Refrigerator prototypes ranking task

six new refrigerator prototypes are tested in the laboratory. for each refrigerator, the electrical power p needed for it to operate and the maximum heat energy that can be removed per second qc, max/δt from its interior are given.

part a

rank these refrigerators on the basis of their performance coefficient.

rank from largest to smallest. to rank items as equivalent, overlap them.

part b

thsee six refrigerators are placed in six identical sealed rooms. rank the refrigerators on the basis of the rate at which they raise the temperature of the room.

rank from largest to smallest. to rank items as equivalent, overlap them.

1) p= 750 w, qc, max/deltat= 1500 j/s

2) p= 400 w, qc, max/deltat= 1200 j/s

3) p= 500 w, qc, max/deltat= 2000 j/s

4) p= 250 w, qc, max/deltat= 1000 j/s

5) p= 500 w, qc, max/deltat= 1500 j/s

6) p= 1000 w, qc, max/deltat= 3000 j/s

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
