the magnitude, m, of an earthquake is defined to be $m = log\frac{i}{s}$, 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.\n-1.5\n-0.5\n1.5\n3.6
Answer
Explanation:
Step1: Definir valores de I y S
Dado que el terremoto es 35 veces más intenso que el estándar, entonces $I = 35S$.
Step2: Sustituir en la fórmula
Sustituimos $I = 35S$ en la fórmula $M=\log\frac{I}{S}$. Tenemos $M=\log\frac{35S}{S}$.
Step3: Simplificar la expresión
$\frac{35S}{S}=35$, así que $M = \log(35)$.
Step4: Calcular el logaritmo
Usando una calculadora, $\log(35)\approx1.544$.
Step5: Redondear
Redondeando a la décima más cercana, $M\approx1.5$.
Answer:
1.5
