The magnitude, M, of an earthquake is defined to be M = log StartFraction I Over S EndFraction, where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a “standard” earthquake, which is barely detectable. What is the magnitude of an earthquake that is 35 times more intense than a standard earthquake? Use a calculator. Round your answer to the nearest tenth.
Answers
Given : The magnitude, M, of an earthquake is defined to be M = log ( I/S) . earthquake is 35 times more intense than a standard earthquake
To find : magnitude of an earthquake
Solution:
The magnitude, M, of an earthquake = log( I/S)
I = Intensity of earth Quake
S = intensity of standard Earth Quake
earthquake is 35 times more intense than a standard earthquake
=> I = 35S
=> The magnitude, M, of an earthquake = log( 35S/S)
= log 35
= 1.544
Magnitude of Earth Quake = 1.5

Answer:
the answer is 1.5
Step-by-step explanation:
i just did this problem and assumed that since we didn't get the number for S, we would only have to find the log of 35. after plugging log35 into a calculator, the answer rounds to 1.5! hope this helps
