(II) At depths of 2000 m in the sea, the pressure is about200 times atmospheric pressure (1 atm = 1.0 x 105 Nm2)By what percentage does the interior space of an ironbathysphere’s volume change at this depth?
(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).
(C) At which depth of an ocean the pressure is be 9.3x10' Pa, when the density of water is 1x10 kg/m³ and pa- 1.01x10 Pa.

Take of the oil to be 900 kg/m3 and its viscosity to be 100(N/m2) s (or 1.00 Pa s).
