2. The following formula models the Richter scale which describes the magnitude, M, of an earthquake with amplitude A where k is a predetermined constant. M = log(1) a. What is the base of the log in this formula? b. Change this formula to exponential form c. Use the above information to explain why a 7.0 earthquake has ten times the amplitude of a 6.0 earthquake d. What would M be if A k? What would that mean in real...
