College Physics Problem 1.34


(a) What fraction of Earth’s diameter is the greatest ocean depth?

(b) The greatest mountain height?


Solution:

Part a

The greatest ocean depth is 104 m, while the earth’s diameter is 107 m

\displaystyle \frac{10^4}{10^7}=\frac{1}{1000}

Part b

The highest mountain is also roughly 104 m.

\displaystyle \frac{10^4}{10^7}=\frac{1}{1000}
