4.Consider the setup shown in the diagram (which is not drawn to scale).The long thin tubehas radiusr= 3.0 mm, and is inserted vertically into a wine barrel filled with water. Thebottom end of the tube is at the top of the water in the barrel.TheradiusRof the lid of the wine barrel is 240 mm. Water is added to thethin tube.Perhaps surprisingly, when the water column reaches aheight of 11 m, the barrel bursts.a)Find the pressure difference between the top of the water column11 mand the point where the tube enters the barrel, when the height of24 cmthe water column is 5.0 m.b)Find the mass of water in the tube when the height is 11 m.c)The next task is to explain why such a small amount of water cancause the barrel to burst.Describe what happens to the pressure ofthe water just under the lid as water is added to the tube.d)** Find the upward force exerted on the lid by the water in thebarrel just before the barrel bursts
