- My professor gave me 5 multiple choice answers for this problem. Does any of these fit the answer that you provided? a. v = 1.4 v0 b. v = v0 c. v = 0.87 v0 d. v = 0.71 v0 e. v = 0.50 v01. An ice cube is placed in a microwave oven. Suppose the over delivers 105 W of power to the ice cube and that it takes 32.200J to melt it. How long does it take for the ice cube to melt? Explain and draws.1.15 When a car has a dead battery, it can often be started by connecting the battery from another car across its terminals. The positive terminals are connected together as are the negative terminals. The connec- Si tion is illustrated in Fig. P1.15. Assume the current i in Fig. P1.15 is measured and found to be 40 A. a) Which car has the dead battery? b) If this connection is maintained for 1.5 min, how much energy is transferred to the dead battery?
