Answer :
To solve this problem, we need to start with the given formula for the Richter scale magnitude:
[tex]\[ M = \log \left(\frac{I}{I_0}\right) \][/tex]
Here:
- [tex]\( M \)[/tex] is the Richter scale magnitude.
- [tex]\( I \)[/tex] represents the intensity of the earthquake we need to find.
- [tex]\( I_0 \)[/tex] is the intensity of the reference earthquake.
In this problem, we are given:
- The magnitude [tex]\( M \)[/tex] is 4.8.
- The intensity of the reference earthquake [tex]\( I_0 \)[/tex] is 1.
Now, substitute the given values into the formula:
[tex]\[ 4.8 = \log \left(\frac{I}{1}\right) \][/tex]
Since dividing by 1 does not change the value of [tex]\( I \)[/tex]:
[tex]\[ 4.8 = \log (I) \][/tex]
Therefore, the equation that can be used to find the intensity [tex]\( I \)[/tex] of the earthquake is:
[tex]\[ 4.8 = \log (I) \][/tex]
This matches option C.
So, the correct answer is:
[tex]\[ \boxed{C} \][/tex]
[tex]\[ M = \log \left(\frac{I}{I_0}\right) \][/tex]
Here:
- [tex]\( M \)[/tex] is the Richter scale magnitude.
- [tex]\( I \)[/tex] represents the intensity of the earthquake we need to find.
- [tex]\( I_0 \)[/tex] is the intensity of the reference earthquake.
In this problem, we are given:
- The magnitude [tex]\( M \)[/tex] is 4.8.
- The intensity of the reference earthquake [tex]\( I_0 \)[/tex] is 1.
Now, substitute the given values into the formula:
[tex]\[ 4.8 = \log \left(\frac{I}{1}\right) \][/tex]
Since dividing by 1 does not change the value of [tex]\( I \)[/tex]:
[tex]\[ 4.8 = \log (I) \][/tex]
Therefore, the equation that can be used to find the intensity [tex]\( I \)[/tex] of the earthquake is:
[tex]\[ 4.8 = \log (I) \][/tex]
This matches option C.
So, the correct answer is:
[tex]\[ \boxed{C} \][/tex]
