Question

richter defined the magnitude of an earthquake to be $m = log\frac{i}{s}$ where $i$ is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and $s$ is the intensity of a \standard\ earthquake, which is barely detectable. the magnitude of a standard earthquake is $m=log\frac{s}{s}=square$

Explanation:

Step1: Simplify the fraction

For the expression $\log\frac{S}{S}$, since $\frac{S}{S} = 1$ (any non - zero number divided by itself is 1).

Step2: Evaluate the logarithm

We know that the logarithm base 10 of 1, $\log(1)=0$ because $10^{0}=1$.

Answer:

0
