A glass bottle of soda is sealed with a screw cap. The absolute pressure of the carbon dioxide inside the bottle is 1.85 x 105 Pa. Assuming that the top and bottom surfaces of the cap each have an area of 3.70 10-4 m2, obtain the magnitude of the force that the screw thread exerts on the cap in order to keep it on the bottle. The air pressure outside the bottle is one atmosphere.
A spring is stretched between two posts. When a pulse is produced at one end of the spring, it makes 4 back-and-forth trips along the spring in 3.4 s. If the pulse has a propagation speed of 12 m/s, how far apart are the posts?
