Problem 9: A drinking straw is placed in a glass of water. A student places their finger over the top opening of the straw and lifts the straw vertically a distance d with the water in the straw staying in the straw. Refer to the figure. Point B is at the surface of the water in the straw and point A is at the surface of the water in the glass. A 1) Enter an expression for the difference in pressure AP= PB-PA between points B and A of the water, in terms of d, the density of the water, Q, and the acceleration due to gravity. g.
