choose the correct answers in the given choices. 1. Two tall buildings are separated by a narrow alleyway. On a windy day,wind gusts move very quickly through the alley. If the buildings are notconstructed properly, which of the following could be a concern when thisoccurs?a. The buildings' windows could be blown outward into the alley because ofair pressure differences.b. The buildings' windows could be blown inward into the building becauseof air pressure differences.c. The buildings' windows could be blown outward into the alley because oftemperature differences.d. The buildings' windows could be blown inward into the building becauseof temperature differences.2. Why when you squeeze on a water hose the water squirts a greaterdistance?a. More water is released from the hose.b. By squeezing on the tube, you are decreasing the cross-sectional areareducing pressure but increasing the velocity of the water.c. Squeezing the hose increases the pressure, thereby increasing thevelocity of the water.d. Squeezing the hose transmits a force through the tube which increasesthe velocity of the water.3. Whicha. Bernoulli's principle can be derived from the principle of conservation ofenergy.b. For a fluid with zero viscosity, an increase in the speed of the fluid occurssimultaneously with a decrease in pressure or a decrease in the fluid'spotentialc.

Air flows faster over the top of the wing decreasing the air pressure.b. Aircraft's wing geometry has a large effect on the amount of lift.c. Newton's laws are typically preferred over the Bernoulli principle toexplaind. All of the above.statement(s)concerningliftis/aretrue.lift.5. Why is it that when you blow over a piece of paper it lifts up?a. Air moves faster over the top of the paper increasing the pressure.b. Air moves faster over the top of the paper reducing the pressure.c. There is an increase in moisture below the paper which lifts it up.d. All of the above.6. Why is the top of an airplane's wing curved?a. To create an area of low pressure above the wingb. To create an area of high pressure above the wingc. To create an equal pressure above and below the wingd. To make the wing look really cool7. According to Bernoulli's principle, when a fluid's pressure decreases, whathappens to the speed of the fluid?a. It stays the same.b. It decreases.c. It increases.d. None these are correct.8. Which of the following statements is not correct?a. The faster a fluid flows, the lesser the pressure it exerts.b. The faster a fluid flows, the greater the pressure it exerts. 7.

Bernoulli's equation can be derived from the conservation of:a. energyb. massc. volumed. pressure10. The statement, "In regions where fluid velocity is smaller, the pressure ishigher, and vice versa", is known as the principle ofa. Pascalb. Bernoullic. Torricellid. Archimedes11.A Styrofoam cylinder, filled with water, sits on a table. You then poke asmall hole through the side of the cylinder, 20 cm below the top of thewater surface.

A needle inserted into a vein during blood transfusion has a gaugepressure of 1,525PA. The density of blood is 1.06 x 103 kg/m3. What is theheight that a blood container is placed so that blood may just enter thevein?a. 0.24 mb. 0.14 mc. 1.4 md. 2.4 m15. Water flows through a pipe as shown below at a velocity of 0.20 m/s. Thediameter at point 1 is 0.5 m. At point 2, which is 3.5m higher than point1, the diameter is 0.30 m.
