A. deanna, who has a mass of 63 kg and who is about 5'10" tall, runs from the intersection at bluemont and manhattan avenue (where the bluemont hotel is), to the top of the hill on manhattan avenue (an elevation change of 120 feet) 1. what is the component of deanna's displacement that is parallel to gravity as she runs from the bottom to the top of the hill? state your answer in meters. 2. what is the magnitude of the force of gravity acting on deanna? 3. explain why the total work that gravity does on deanna is negative in this situation 4. what is the total work that gravity does on deanna in this situation? 5. how much work does deanna do against gravity as she runs up the hill? state your answer both in joules and in kilocalories 6. explain why the total work that gravity does on deanna is not affected by the shape of the hill 7. calculate the total increase in deanna's gravitational potential energy from running up the hill. show your reasoning. 8. deanna burns about 50 kilocalories as she runs up the hill. compare this value to the amount of work that deanna does against gravity. does the relations hip between these values make sense? explain

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
