a. Water has many unique properties. What are adhesive forces and cohesive forces in water? How does the polarity of a water molecule affect the formationion of water droplets?b. Write one or two sentences that summarize Pascal’s principle. (1 point)c. A force of 12,000 N is exerted on a piston that has an area of 0.020 m2. What is the area of a second piston that exerts a force of 24,000 N? d. Describe an object that floats and an object that sinks by relating each one’s density to the density of the fluid. e. A cannon is recovered from a shipwreck. What happens to the buoyant force on the cannon as it is lifted out of the water? Explain your reasoning. (f. An object sinks in both water and oil. Oil is less dense than water. Compare the buoyant force acting on the object in each liquid, then compare the volume of each liquid that is displaced. g. Use the flow rate equation to help explain how the motion of a whitewater raft changes as the river channel becomes narrower. (1 point)
