PHYSICS 6B Ch.13 Worksheet Solutions www.clas.ucsb.edu/staff/vince/ 1) The Titanic was found in 1985 lying at the bottom of the North Atlantic at a depth of 4 kilometers. What is the pressure at this depth? (assume standard atmospheric pressure and that the density of seawater is 1025 kg/m 3 ) P 0 =1.1·10 5 Pa; P total =4.01·10 7 Pa 2) One day while swimming below the surface of the ocean, you let out a small bubble of air from your mouth. As the bubble rises toward the surface, does its diameter (a) increase (b) decrease or (c) stay the same? Pressure decreases as the bubble rises, allowing the bubble to expand. 3) A flask of water (not completely full) rests on a scale. If you dip your finger into the water, without touching the flask, does the reading on the scale (a) increase (b) decrease, or (c) stay the same? One way to think about this one: consider the depth of the water it rises when you put your finger in. So the pressure at the bottom of the flask is larger than before. This pressure is pushing down on the scale, making the
