Answer:
7.9982
Step-by-step explanation:
-The function for an earthquake's magnitude is given by R = 0.67log(0.37E) + 1.46
-E is energy in kwh.
#For 15,500,000,000 kilowatt hours the magnitude would be:
[tex]R = 0.67\ log(0.37E) + 1.46,\ \ E=15,500,000,000 \ kwh\\\\\therefore R=0.67 \ log(0.37\times 15,500,000,000)+1.46\\\\\\=7.9982[/tex]
Hence, the earthquakes magnitude is 7.9982
