1. a solution is dripped into an initially empty test tube at a rate q; = q;(t) [mm³/s]. as for the geometry of the test tube, its bot-tom portion is

a half-sphere with radius R[mm], which is connected to a cylinder of height L [mm] (top portion). h(t) [mm] in the test(a) (4 points) write a dynamic model for the liquid level h =tube. it should take the form of a piece wise differential equation in h. The density of the liquid, p [g/mm³], is constant. (b) (1 point) if q; is nonzero and constant (not changing with time), then will the liquidlevel h(t) increase faster when h(t) < R or when h(t) > R?
