Question

Earthquake measured 4.9 on the Richter scale. Determine approximately how many times strong the wave amplitude

Answer 1

Answer:

$a=15849*a_{o}$

Step-by-step explanation:

The Richter scale is a logarithmic scale

$\log_{10}\left( \frac{a}{a_{o}} \right)=4.9\\\left( \frac{a}{a_{o}} \right)=10^{4.9}\\\left( \frac{a}{a_{o}} \right)=10^{4.9}\\\left( \frac{a}{a_{o}} \right)=15,849\\{a}=15,849*{a_{o}}$
