Final answer:
In this case, the Richter scale reading of the second earthquake can be calculated using logarithms which is 9.5.
Step-by-step explanation:
The Richter scale is a logarithmic scale used to quantify the energy produced by an earthquake. The numbers on the Richter scale represent the amplitude of seismic waves, which is directly related to the energy released by the earthquake.
In this question, we are given that one earthquake has a Richter scale reading of 6.5. The second earthquake is stated to be 10000 times as strong as the first one.
Since the Richter scale is logarithmic, we can use logarithms to calculate the Richter scale reading of the second earthquake.
Let's denote the Richter scale reading of the second earthquake as x. We know that the second earthquake is 10000 times as strong as the first one, so we can set up the equation 10^(x-6.5) = 10000.
Solving this equation, we find x = 9.5. Therefore, the Richter scale reading of the second earthquake is 9.5.
