Major
an earthquake registered 7.4 on the richter scale. if the reference intensity of this quake was 2.0 × 10^11, what was its intensity?

The correct answer would be: C. 5.02 x 10^18

Here's how you solve it!

Since the earthquake registered is 7.4 on the scale let it represent RS=7.4

The reference intensity is 2.0 x 10^11 so let it represent RI= 2.0 x 10^11

Now you need to use the formula.

Then we need to plug in the values for the formula

x x

x

Hope this helps! :3

a = 11 : 4

b = 38

c = 1 for every 6
