for... D Question 13 2 pts An air-conditioner is used to maintain a constant temperature for a large medical specimen storeroom. Its average power consumption is rated at 215 W? How many giga-joules of energy does the air-conditioner use in one year (1 GJ = 109 J)? D Question 14 2 pts A 96.6 g toy car travels up a ramp to a step 0.182 m above its starting point. If its initial speed is 2.02 ms" and its final speed is 0.22 ms , how much work was done against friction? Please take the gravitational acceleration to be g = 9.80 m.s-2 and enter your answer in Joules. D Question 15 2 pts A 1,411 kg elevator car rises 38.4 m at constant speed. The car experiences some friction of 96 N as it moves. Calculate the work done by the elevator cable in this process. Please take the gravitational acceleration to be g = 9.80 m.s" and enter your answer as an absolute value in Joules
