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?b. The mass set into motion is a tiny 1.0 × 10-12 kg. What is the resulting acceleration?

Pressure cookers have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). How much force (in N) must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 23.0 cm in diameter and the gauge pressure inside is 3.50 atm? Neglect the weight of the lid. N
Pressure cookers use water at very high pressures to cook food very quickly. They have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). a. How much force, in newtons, must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 27.5 cm in diameter and the gauge pressure inside is 0.95 atm? Neglect the weight of the lid.

Three liquids that will not mix are poured into a cylindrical container. The volumes and densities of the liquids are 0.45 L, 2.6 g/cm³; 0.20 L, 1.0 g/cm³; and 0.40 L, 0.65 g/cm³. What is the force on the bottom of the container due to these liquids? One liter = 1 L = 1000 cm³. (Ignore the contribution due to the atmosphere.) N
