Figure 13-42 shows, not to scale, a cross section through the interior of Earth. Rather than being uniform throughout, Earth is divided into three zones: an outer crust, a mantle, and an inner core. The dimensions of these zones and the masses contained within them are shown on the figure. Earth has a total mass of 5.98 × 10 24 kg and a radius of 6370 km. Ignore rotation and assume that Earth is spherical, (a) Calculate a g at the surface. (b) Suppose that a bore hole (the Mohole) is driven to the crust-mantle interface at a depth of 25.0 km; what would be the value of a g at the bottom of the hole? (c) Suppose that Earth were a uniform sphere with the same total mass and size. What would be the value of a g at a depth of 25.0 km? (Precise measurements of a g are sensitive probes of the interior structure of Earth, although results can be clouded by local variations in mass distribution.) Figure 13-42 Problem 27.

Using the metric (top) scale only, what units are being used for the long lines
with the numbers? Hint: Remember that 2.54 cm = 1 in.
2.
What are the units of the small lines?
3. How many decimal places should be recorded using this tool?
4. What is the length of the red line? Note: Make sure to use the correct units
and decimal places.
5. Now observe your ruler. What metric units are used on your ruler?
6. How many decimal places should you record when using your ruler?
