Nutrients dissolved in water are carried to upper parts of plants by tiny tubes partly because of the capillary effect. determine how high the water solution will rise in a tree in a 0.0026-mm-diameter tube as a result of the capillary effect. treat the solution as water at 20°c with a contact angle of 26°. the surface tension of water at 20°c is σs = 0.073 n/m. take the density of water to be 1000 kg/m3.

Aparticle moves along a straight line such that its acceleration is a=(4t^2-2) m/s, where t is in seconds. when t = 0, the particle is located 2 m to the left of the origin, and when t = 2, it is 20 m to the left of the origin. determine the position of the particle when t=4s.
