Some jellyfish can eject stingers with remarkable force and speed. One species does this by building up a 15 MPa gauge pressure that pushes against the base of a 2.0-μm-diameter stylet, forcing it outward.
A. What force does the excess pressure exert on the stylet? and Units.
B. The mass set into motion is a tiny 1.0×10−12kg. What is the resulting acceleration? and Units.
