Question

On April 11, 2012, two earthquakes were measured off the northwest coast of Sumatra. The first had a magnitude of 8.6. The second had a magnitude of 8.2. By what approximate factor was the intensity of the first earthquake greater than the intensity of the second earthquake?

Answer 1

Answer:by a value of 0.4 it was greater. Hope it helps u , plsz let me k

Step-by-step explanation:

Answer 2

Concept:

Factor increase here means the multiplier. Eg, population increased by a factor of 10 in 5 year means the population now is 10 times the population of what it was 5 year ago.

Given:

First earthquake= 8.6

Second Earthquake= 8.2

Find:

Factor the intensity of first earthquake is greater than second.

Solution:

Let the factor be f.

$8.2*f= 8.6\\\\f=8.6/8.2\\\\f=1.0487$

The intensity of the First Earthquake was greater than the second by a factor of 1.0487
