When a.22-caliber rifle is fired, the expanding gas from the burning gunpowder creates a pressure behind the bullet. This pressure causes the force that pushes the bullet through the barrel. Suppose the barrel has a length of 0.699 m and an opening whose radius is 2.65 x 103 m. A bullet (mass = 2.6 x 10³ kg) has a speed of 428 m/s after passing through this barrel. Ignore friction and determine the average pressure of the expanding gas. Number Units

An aquatic organism needs to be neutrally buoyant to stay at a constant depth. Fish accomplish this with an internal swim bladder they can fill with air that they take in from the water through their gills. One complication is that the pressure in the swim bladder matches that of the surrounding water, but the water pressure changes with depth. Because the volume of a gas is inversely proportional to pressure (as you may already know if you have studied the ideal-gas law), the volume of air in a fish's swim bladder decreases with depth unless the fish actively adds more air.
If you blow a thin stream of air with a speed of 7.2 m/s out of your mouth, what is the overpressure in your mouth? Assume that the speed of the air in your mouth is (nearly) zero.
A cylinderis fitted with a piston beneath which is a spring, as in the attachment. The cylinder is open to the air at the top. The sprink constant is 4300 N/m. The piston has negligible mass and a radius of 0.032. When the air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress? How much work does the atmospheric pressure do in compressing the spring.

You have a tube where water enters at a velocity of 10.0 m/s, ascends 5.0 m, and then exits. The pressure pushes the water in at 250 kPa, and is measured come out at 150 kPa. The outcoming water is, faster than the incoming water. slower than the incoming water. the same speed as the incoming water.
