You are a passenger on a spacecraft. For your survival and comfort, theinterior contains air just like that at the surface of the Earth. The craftis coasting through a very empty region of space. That is, a nearlyperfect vacuum exists just outside the wall. Suddenly, a meteoroidpokes a hole, about the size of a large coin, right through the wall nextto your seat. (a) What happens? (b) Is there anything you can or shoulddo about it?

The hole is created by meteoroid when spacecraft was passing through nearly vacuum region of space,…

A lost shipping container is found resting on the ocean floor and completely submerged. The container is 6.3 m long, 2.9 m wide, and 2.9 m high. Salvage experts attach a spherical balloon to the top of the container and inflate it with air pumped down from the surface. When the balloon's radius is 1.6 m, the shipping container just begins to rise towards the surface. What is the mass of the container? Ignore the mass of the balloon and the air within it. Do not neglect the buoyant force exerted on the shipping container by the water. The density of seawater is 1025 kg/m³. Number i Units
NASA is designing a mission to explore Titan, the largest moon of Saturn. Titan has numerous hydrocarbon lakes containing a mix of liquid methane and liquid ethane in unknown proportions. As part of the mission, a small submersible vehicle will explore Kraken Mare, the largest of these lakes. Assuming the maximum depth of Kraken Mare is less than 450 meters [m], how much total pressure units of in atmospheres [atm] must the submersible be designed to withstand? Assume the surface pressure on Titan is 146 kilopascals [kPa], the surface temperature is 93 kelvins [K], and the gravity is 1.35 meters per second squared m/s2. The specific gravity of liquid methane is 0.415 and the specific gravity of liquid ethane is 0.546.

Your dorm has an amateur hour every Friday night. Since you have a tremendous lung capacity, you challenge everyone to a lung capacity competition which is conducted by blowing air through one straw which in turn pulls water up through another straw, as shown in the figure. The straws are identical and have a diameter of 0.58 cm, you are able to exhale 1.4 liters of air through the horizontal straw in as little as 2 seconds, and the density of air is 1.29 kg/m³. Determine the following. (a) speed of the air as it travels through the horizontal straw m/s (b) height to which water rises in the vertical straw cm
Humans evolved in Earth's atmosphere, therefore the pressures interior to the body are relatively close to atmospheric pressure. Because the differences between internal body pressures and atmospheric pressure are so small, individuals have a difficult time gauging the magnitude of atmospheric pressure. Suppose an individual is lying on his stomach with sheets of paper stacked on his back. If each sheet of paper has a mass of 0.00380 kg and is the standard letter size of 8.5 in by 11 in (0.216 m by 0.279 m), how many sheets must be stacked to produce pressure on his back equal to atmospheric pressure (roughly 101325 Pa)? sheets of paper required:
You are with an excursion party on an exploration of the surface of Mars. You find a small lake of water of that 1.76 m. Assume the density of the freshwater is unchanged on Mars. You measure the absolute pressure at the bottom of the lake to be one 161,800 Pa. What is the absolute pressure (in atm) at the surface of the lake. Assume the value of G on Mars is 3.72 m/s^2

AP-1 A 155 kg chunk of iron is floating in a large container of mercury. The densities of iron and mercury are 7,850 kg/m³ and 13,600 kg/m³, respectively. (a) What % of the iron chunk's volume is submerged below the surface of the mercury? (b) What force would need to be applied to the iron chunk to completely submerge it?
A 0.504 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plunger. The cylinder comes to rest some distance above the plunger. The plastic tube has an inner radius of 5.88 mm and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal cylinder by a factor of 3.03, what is the initial acceleration a of the metal cylinder? Assume the pressure outside of the tube is 1.00 atm and that the top of the tube is open to the air.
A 0.458 kg metal cylinder is placed inside the top of a plastic tube, the lower end of which is sealed off by an adjustable plunger. The cylinder comes to rest some distance above the plunger. The plastic tube has an inner radius of 6.90 mm and is frictionless. Neither the plunger nor the metal cylinder allow any air to flow around them. If the plunger is suddenly pushed upwards, increasing the pressure between the plunger and the metal cylinder by a factor of 2.07, what is the initial acceleration a of the metal cylinder? Assume the pressure outside of the tube is 1.00 atm and that the top of the tube is open to the air. a = m/s?
