Hello. I am doing a review sheet for my Pre-Calculus final and one of the questions has me stumped. I'm going through our notes and we never did a problem like this in class. Any help would be greatly appreciated. Thank you.
Find the Richter scale magnitude of an earthquake that releases energy of E= 1000 E_0 . Then find the energy released by an earthquake that measures 5.0 on the Richter scale given that that E_0= 10^{4.40}. Finally find the ratio in energy released between an Earthquake that measures 8.1 on the Richter scale and an aftershock measuring 5.4 on the scale. Use the formula R = 2/3 log E/Eo
A) R = 2, E = 7.94 x 10^{11} joules and the ratio E1/E2 = 10200/1
B) R = 2, E = 7.94 X 10^{10} joules and the ratio E1/E2 = 11200/1
C) R = 2, E = 7.94 X 10^{11} joules and the ratio E1/E2 = 11200/1
D) R = 3, E = 7.94 X 10^{11} joules and the ratio E1/E2 11200/1
E) R = 2, E= 5.94 X 10^{11} joules and the ratio E1/E2 = 11200/1
Which answer would be the correct one?
