You are A. You are sitting near at the edge of a merry-go-round, a distancefrom the center If the merry-go-round is spinning clockwise at a constant rate, determine the magnitude and direction of the acceleration from your perspective of an actually stationary object (⃗⃗=0)at the 3 other “corners” of the merry-go-round. That is, if you are at the south end, a stationary object at the west, east, and north ends of the merry go round, same distance from the center as you, .You can describe the direction in any way you wish, but you must be specific. Angles or slopes are required, if necessary! Please note, ⃗⃗⁄is not obvious in this problem and must be found. This is based on your perception, so it must include the rotating reference frame, using the equation on the previous page. Note: Your reference rotates with the merry-go-round. Express the answer in your reference frame. Also note: The equations require you to find your true acceleration, ⃗. You are traveling in a circular path at constant speed, so your acceleration should be easy to find based on stuff we’ve already learned.

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
