Imagine an ideal (Carnot) refrigerator that keeps soda bottles chilled to a temperature of about 280 KK. The refrigerator is located in a hot room with a temperature of about 300 KK. Because of the imperfect insulation, 5.00 JJ of heat is absorbed by the refrigerator each hour. How much electrical energy EEE must be used by the refrigerator to maintain the temperature of 280 KK inside for one hour?

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
