Aglass bottle of soda is sealed with a screw cap. the
absolute pressure of the carbon dioxide inside the bottle
is1.80*105 pa. assuming that the top and bottomsurfaces
of the cap each have an area of 4.10*10-4m2,
obtain the magnitude of the force that the screwthread exerts on
the cap in order to keep it on the bottle. the air pressure outside
the bottle is one atmosphere.
