Introduction
|
Capillary Action
|
|
Peter has joined the Sandia
National Laboratory as an undergraduate research assistant through a
summer intership program. To let his interns better understand the
property of surface tension, the laboratory director decides to demonstrate
surface tension effects through capillary action. However, before starting,
he asks each intern what the height will be for two different radii.
