9. ssm When a .22-caliber rifle is fired, the expanding gas from the burn-ing gunpowder creates a pressure behind the bullet. This pressure causesthe force that pushes the bullet through the barrel. The barrel has alength of 0.61 m and an opening whose radius is 2.8 × 10-³ m. A bullet(mass = 2.6 X 10-³ kg) has a speed of 370 m/s after passing through thisbarrel. Ignore friction and determine the average pressure of the expand-ing gas.

Given data The length of the barrel is s=0.61 m The radius is r=2.8×10-3 m The mass of the bullet is…

A metallic container of fixed volume of 2.5103 m3 immersed in a large tank of temperature 27 contains two compartments separated by a freely movable wall. Initially, the wall is kept in place by a stopper so that there are 0.02 mol of the nitrogen gas on one side and 0.03 mol of the oxygen gas on the other side, each occupying half the volume. When the stopper is removed, the wall moves and comes to a final position. The movement of the wall is controlled so that the wall moves in infinitesimal quasi-static steps. (a) Find the final volumes of the two sides assuming the ideal gas behavior for the two gases. (b) How much work does each gas do on the other? (c) What is the change in the internal energy of each gas? (d) Find the amount of heat that enters or leaves each gas.
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 0.557 m and an opening whose radius is 2.94 x 10-3 m. A bullet (mass = 2.6 x 10-3 kg) has a speed of 467 m/s after passing through this barrel. Ignore friction and determine the average pressure of the expanding gas.

There are two important isotopes of uranium- 235 U and 238 U; these isotopes are nearly identical chemically but have different atomic masses. Only 235 U is very useful in nuclear reactors. One of the techniques for separating them (gas diffusion) is based on the different average velocities Vrms of uranium hexafluoride gas. UF6. (a) The molecular masses for 235 U UF6 and 238 U UF6 are 349.0 g/mol and 352.0 g/mol, respectively. What is the ratio of their average velocities?
Cephalopods, such as octopi and squids, can use a form of jet propulsion to move quickly through the water. This technique of locomotion is useful in providing short bursts of speed to catch prey and to avoid predators, and it gives them the title of fastest marine invertebrates. Oxygenated water is taken in by the cephalopod and then expelled by muscular contraction through an opening called the hyponome. Assume a 5.0 kg squid draws in 0.44 kg of water and then quickly (in 0.12 s) expels this water at a speed of 10.1 m/s. What is the recoil speed of the squid just after the water is expelled?

Boston molasses disaster. On January 15, 1919, a vat of molas- ses in Boston's North End burst. A wave of molasses with height 10 m sped through the streets at 16 m/s (about 35 mi/h), killing 21 people and resulting in great property damage . The vat was 15 m high, 27 m in diameter, and held 2.3 x 10° U.S. gal of molasses. In the vat's hasty construction, its soundness had been tested only with water 0.150 m deep. What was the pressure on its wall at the base (a) during the test and (b) when filled with molas- ses with density 1.42 x 10³ kg/m³?
