asked • 12/22/20The Richter Scale reading of an earthquake is based on a logarithmic equation.
The Richter Scale reading of an earthquake is based on a logarithmic equation.
Suppose: R = log (A/A0)
where
A - the measure of the amplitude of the earthquake wave
A0 the amplitude of the smallest detectable wave (or standard wave).
An earthquake is measured with a wave amplitude A = 0.2397 while the smallest detectable wave A 0 is measured at 0.0001 cm. What is the magnitude of this earthquake using the Richter scale, to the nearest tenth?
PLEASE give answer and explain

Hello, nice to meet you
We know the formula R = log (A/A0)
log(0.2397/0.0001)=3.37966803 around neartest 10 is 3.4.
You need to plug into the formula given. They tell which one to plug to in that the basis of the log.

Log(A/A0) = log(0.2397/0.0001) = log(2397) = 3.379 ⇒ 3.4 Not much to explain. Plug in the variables and solve. Is there more to it that I don't know?12/22/20
