A drinking straw is placed in a glass of water. A student placestheir finger over the top opening of the straw and lifts the strawvertically a distance d with the water in thestraw staying in the straw. Refer to the figure. Point B is at thesurface of the water in the straw and point A is at the surface ofthe water in the glass.
A) Enter an expression for the difference inpressure ΔP = PB - PA betweenpoints B and A of the water, in terms of d, thedensity of the water, ρ, and the acceleration due togravity, g.
