1. As you climb a mountain, your ears "pop" because of the changes in atmospheric pressure.
(a) In which direction does your eardrum move as you climb up? inward outward eardrum does not move Give your reasoning.
(b) In which direction does your eardrum move as you climb down? inward outward eardrum does not moveGive your reasoning.
2. A large closed tank is completely filled with water. A valve is then opened at the bottom of the tank and water begins to flow out. Whenthe water stops flowing, will the tank be completely empty, or will there still be a noticeable amount of water in it? tank will have a noticeable amount of water in it tank will be completely empty Explain your answer.
3. Could you use a straw to sip a drink on the moon?yes no not enough information to decideJustify your answer.
4. A scuba diver is below the surface of the water when a storm approaches, dropping the air pressure above the water. Would a sufficiently sensitive pressure gauge attached to his wrist register this drop in air pressure?yes, if the gauge was designed to measure gauge pressure yes, if the gauge was designed to measure absolute pressure yes, if the gauge was designed to measure partial pressure no, the gauge would not register this drop in air pressureGive your reasoning.
5. A steel beam is suspended completely under water by a cable that is attached to one end of the beam, so it hangs vertically. Another identical beam is also suspended completely under water, but by a cable that is attached to the center of the beam so it hangs horizontally. Which beam, if either, experiences the greater buoyant force? Neglect any change in water density with depth.both beams experience the same buoyant force the vertically suspended beam the horizontally suspended beam
Provide a reason for your answer.
6. A glass beaker, filled to the brim with water, is resting on a scale. A block is placed in the water, causing some of it to spill over. The water that spills is wiped away, and the beaker is still filled to the brim. How do the initial and final readings on the scale compare if the block is made from the following materials?
(a) woodinitial reading is greater than the final reading initial reading is lesser than the final reading initial reading is equal to the final reading
Explain your answer, using data from Table 11.1 and Archimedes' principle.
(b) ironinitial reading is greater than the final reading initial reading is lesser than the final reading initial reading is equal to the final readingExplain your answer, using data from Table 11.1 and Archimedes' principle.
7. On a distant planet the acceleration due to gravity is less than it is on earth. Would you float more easily in water on this planet than on earth?yes no floating on water on the planet would be the same as that on earthAccount for your answer.
8. Put an ice cube in a glass, and fill the glass to the brim with water. When the ice cube melts and the temperature of the water returns to its initial value, would the water level drop, remain the same, or rise (causing water to spill out)? water leve remains the same water level rises water level drops Explain what you would observe in terms of Archimedes' principle.
9. As a person dives toward the bottom of a swimming pool, the pressure increases noticeably. Does the buoyant force also increase? Neglect any change in water density with depth. yes no not enough information to decide Justify your answer.
10. Concept Simulationreviews the central idea in this question. The cross-sectional area of a stream of water becomes smaller as the water falls from a faucet. Account for this phenomenon in terms of the equation of continuity. What would you expect to happen to the cross-sectional area when the water is shot upward, as it is in a fountain? cross-sectional area remains the same cross-sectional area becomes larger cross-sectional area becomes smaller Explain.
11. Have you ever had a large truck pass you from the opposite direction on a narrow two-lane road? You probably noticed that your car was pulled toward the truck as it passed. What can you conclude about the speed of the air between your car and the truck compared to that on the opposite side of the car? the speed of the air between the car and the truck is lesser than that on the opposite side of the car the speed of the air between the car and the truck is greater than that on the opposite side of the car the speed of the air between the car and the truck is the same as that on the opposite side of the car Provide a reason for your answer.
12. Hold two sheets of paper by adjacent corners, so that they hang downward. They should be parallel and slightly separated, so that you can see the floor through the gap between them. Blow air strongly down through the gap. Do the sheets move further apart, or do they come closer together?Discuss what you observe in terms of Bernoulli's equation.
