- (a) What fraction of Earth's diameter is the greatest ocean depth? (b) The greatest mountain height?Earth’s atmosphere is in hydrostatic equilibrium. What this means is that the pressure at any point in the atmosphere must be high enough to support the weight of air above it. How would you expect the pressure on Mt. Everest to differ from the pressure in your classroom? Explain why.1. The volume of a rock is found to be 0.00015 m3. If the rock’s specific gravity is 2.60, what is its weight? 2. If a liquid has a specific gravity of 1.7, what is the density in slugs per cubic feet? What is the specific weight in pounds-force per cubic feet? The Answer should be like this (1.2 and 102)
- 1. What is the relationship between density, specific gravity, mass, and volume? 2. What is the relationship between pressure to area and force? 3. What is the relationship of pressure to fluid density and depth?A semi sphere bowl with a radius of 2.6cm and mass of 70g is placed like a boat in a swimming pool. Loaded with 1 peso pennies. If the mass and the volume of one peso penny is 6.1 g and 0.30cm^3. How many one peso pennies can be placed in the bowl without sinking?Oceans 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. Oceans
