- Make a plot of pressure vs altitude for a hydrostatic, isothermal atmosphere on Earth, assuming a surface pressure of 1 atm.V A solid brass (bulk modulus 6.7 x 1010 N/m²) sphere is subjected to a pressure of 1.0 x 105 Pa due to the earth's atmosphere. On Venus the pressure due to the atmosphere is 9.0 x 106 Pa. By what fraction Ar/ro (including the algebraic sign) does the radius of the sphere change when it is exposed to the Venusian atmosphere? Assume that the change in radius is very small relative to the initial radius. Number i UnitsHumans 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 0.00360 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 a pressure on his back equal to atmospheric pressure (roughly 101325 Pa)? sheets of paper required:
- In the Challenger Deep of the Marianas Trench, the depth of seawater is 10.9 km and the pressure is 1.16×108Pa (about 1.15×103atm). (a) If a cubic meter of water is taken from the surface to this depth, what is the change in its volume? (Normal atmospheric pressure is about 1.0×105Pa. Assume that k for seawater is the same as the freshwater value given in Table) (b) What is the density of seawater at this depth? (At the surface, seawater has a density of 1.03×103kg/m)"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.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:

Provide your answer in lbs with 2 decimals.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
