(III) The Earth is not a uniform sphere, but has regions of varying density. Consider a simple model of the Earth divided into three regions-inner core, outer core, and man- tle. Each region is taken to have a unique constant density (the average density of that region in the real Earth): Region Radius (km) Density (kg/m³) Inner Core 0-1220 13,000 Outer Core 1220–3480 11,100 Mantle 3480–6380 4400 (a) Use this model to predict the average density of the entire Earth. (b) If the radius of the Earth is 6380 km and its mass is 5.98 × 1024 kg, determine the actual average density of the Earth and compare it (as a percent difference) with the one you determined in (a).

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 0.00360 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)"

Determine the thickness of a hollow aluminum sphere with a mass of o.35g and has an outer radius of o.50 cm if the density of the aluminum is 2700kg/m^3.
In NCAA softball, the softball is a sphere with a circumference between 11.88 and 12.13 inches [in] and a mass between 177 and 198 grams [g). You find a ball and determine the mass is 180 grams [g] and the specific gravity is 0.32. While this specific gravity seems low for a solid, the ball is not made of a completely solid material but is instead filled with a sponge-like substance. Determine the radius of the ball you found and report the value in units of inches [in]. Click the icon to view the table of common derived units in the SI system.
