By using formula given above, M= log(w/w_0), we can find
10^M= w/w_0, it means 10^M.w_0,= w
but M=6.5, so 10^6.5=3162277,66
the seismic waves of the Caracas earthquake were 3162277,66 times more powerful of the standard seismic waves
My calculator shows that
(2.1)/(1.488) = 1.41129
which is approximate. If you want the result to two decimal places, then it would be 1.41 and not 1.40
Try 1.41 and it should work out, assuming your teacher wants two decimal places.
Do you know what you need to do to solve this problem?
D. (I used 3.14 as pi so my answer was a little off so I just went with the one closest to my answer)
