Students have asked these similar questions
the Mariana trench is the deepest known point on earth.
with a depth of 10984m.
what is the depth pressure at the bottom of the trench if the mass density of salt water is 1030kg/m^3

A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You pull out your old geology text and look up gold in the mineral table and read that its density is 19.3 g/cm3. You measure the cube and find that it is 3cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?

- Water flows through a venturi meter. At the constricted section where the area is 24cm2, the pressure is 10.2 N/cm2 , and at the section where the area is 64cm2, the pressure is 18.0 N/cm2 . Determine the rate of flow.arrow_forwardOceans cover 71% of the surface of the Earth, and have an average depth of 3700 m. The planet has an average radius of 6370 km, so that the oceans form a very thin layer overall! The deepest known part of the ocean is the Mariana Trench, north of Papua New Guinea and east of the Phillipines, with a depth of almost 11000 m. If Mount Everest was placed at the bottom of the Mariana Trench, it would still be submerged by more than 2000 m! Estimate the volume of water contained in all of the oceans on Earth, and give the result in SI units. Be sure to state your assumptions with your calculation.

- Many of the cities in Holland are below sea level, and the sea is held back by a series of levies, called dikes. A story tells of a young Dutch boy named Hans Brinker, who was walking home along the dikes from school one day, and saw a small leak. He realized this was a real problem, so he stuck his thumb in the hole and cried for help. Imagine that the hole is 10.0 feet (3.08 meters) beneath the level of the sea beyond. How much pressure is being exerted at the hole? Hans’ thumb has a surface area of 0.895 square centimeters (Think: How many square centimeters in a square meter?). How much force does he feel on his thumb? Do you think that is a reasonable amount of force for a child to balance? Normally, to find the total pressure exerted, we’d have to add atmospheric pressure to the pressure exerted by the seawater. Why do we not have to worry about that here? *Problems involving the buoyant force are Newton’s Second Law problems, and should be solved with the same process!*arrow_forwardThe density of air near earth's surface is 1'3 kg/m and the atmospheric pressure is 10 x 10 N/m?. If the atmosphere had uniform density, same as that observed at the surface of the earth, what would be the height of the atmosphere to exert the same pressure ? 2arrow_forwardQ2. To illustrate the tremendous pressure that exists deep underground where granite bodies are emplaced, answer the following question. Stone Mountain granite in Georgia has an area of 4.1 square kilometers and was emplaced 16 km deep. If we assume that Stone Mountain granite is present in an area that has more or less a rectangular shape with dimensions of 1 km by 4.1 km and that it was buried under 16 km of metamorphic rock material with a density of 2.6 g/cm³. We can calculate the weight of metamorphic rock over the Stone Mountain granite when it was emplaced and before erosion removed that material. First, we need the volume of the metamorphic rock that existed over Stone Mountain. The volume of a rectangular prism that represents the metamorphic rock over Stone Mountain is length x width x height. In our case: 1 km x 4.1 km x 16 km= 65.6 km³ Now we can use the relationship: Density x Volume= Mass However, we need to change our density units from 2.6 g/cm3 to kg/km3, and then we…arrow_forward
