2.) It is well known that you can trap liquid in a drinking straw by placing the tip of your finger over the top while the straw is in the liquid and then lifting the straw out. The density of water is 1.0 g/cm3, and assume atmospheric pressure is 101.3 kPa. When the straw has been removed from the liquid (a) What is the net force on the cylinder of trapped liquid (treat al the liquid as one (b) Draw a free-body diagram on the cylinder of trapped liquid. What force keeps (c) Is the gas pressure inside the straw (between the liquid and your finger) greater (d) If your answer to part (c) was "greater or "less", how did the pressure in- (e) If the straw has a radius of 2.0mm, and you have trapped a column of water which object) the liquid from falling out of the straw? than, less tn, or eq to atmospheric pressure? Explain crease/decrease from atmospheric pressure? is 10 cm high, determine the gas pressure between the liquid and your finger. Give ar answer as a percentage of atmospheric pressure (i.e. P- × Pan.) =
