Answer:
Explanation:
Given:
radius of capillary, 
angle of contact, 
density of water, 
surface tension of water, 
height, h = ?
We have the equation for the height of meniscus as:
No, the capillary action alone cannot be the mechanism of water transportation to the top of the trees. Transpiration also creates a suction pressure in the xylem complementary to the ascent of sap and cohesion of water being the other causes of movement of water up in the plants.
