Unformatted text preview: 1. Wanda watches the fish in her fish tank and notices that the angel fish like to feed at the water’s surface, while the catfish feed 0.300 m below at the bottom of the tank. If the average density of the water in the tank is 1000. kg/m3, what is the pressure on the catfish? 2. Phyllis is being fed intravenously in her hospital bed from a bottle 0.400 m above her arm that contains a nutrient solution whose density is 1025 kg/m3. What is the pressure of the fluid that is going into Phyllis’ arm? 3. Palmer drops an ice cube into his glass of water. The ice, whose density is 917 kg/m3, has dimensions of 0.030 m x 0.020 m x 0.020 m, as shown in the diagram. What is the buoyant force acting on the ice? 4. Every Sunday morning, Dad takes the family trash to the trash compactor in the basement. When he presses the button on the front of the compactor, a force of 350 N pushes down on the 1.3-cm2 input piston, causing a force of 22,076 N to crush the trash. What is the area of the output piston that crushes the trash?...
