Step 1. Redo the Practice Set Redo all questions, but this time give yourself as much time as you need, and feel free to consult any resources or other people you need for help. Make sure at the end that you truly understand at least one approach correctly answering all of the questions 1. Josh builds three pendulum clocks. One is for keeping time on Mercury, one is for keeping time Earth, and the other is for keeping time on Jupiter. The accelerations due to gravity on these planets are gy = 3.7m/s?, ge =9.8m/s?, and g; = 23.1m/s\" respectively. The clocks are designed to tick once per second on the surface of their respective planets, so despite differences in gravitational acceleration, they all keep time identically (i.e. if they were to start in sync, they would remain in sync). In each of the following answer choices, there is a diagram showing the length of the pendulum for each clock. Lengths are all to scale which means the relative lengths of the pendulums are correct in each diagram. Which diagram correctly depicts the lengths of the pendulums? Fill in the circle next to only one answer choice. Mercury Earth Jupiter Mercury Earth Jupiter O O Mercury Earth Jupiter Mercury Earth Jupiter O J @/ 2. The following are descriptions of three heat pumps A, B, and C operating as heaters. Heat Pump A. Over the course of running for a day, the pump consumes 2kWh of work and outputs 4 kWh of heat. Heat Pump B. Over the course of running for an hour, the pump consumes 500 Wh of work and it absorbs 0.25kWh of heat from the \"cold\" region. Heat Pump C. The heat pump is heating a house. As it runs, it extracts heat from cold ground outside (this is called a ground-source heat pump) and pumps heat into the air in the house. The temperature in the ground outside is 10F below the freezing point of water, and the temperature inside the house is 71F. The pump is running at 10% if its maximum coefficient of performance. Which of the following answer choices gives the correct ranking of the heaters from lowest to highest coefficient of performance? Fill in the bubble gorresponding to your answer.
