Answer:
The intensity of the first earthquake is 6.31 times the second one
Step-by-step explanation:
The given formulae is M=log(
)
Here for both the earthquakes the value of S is same.
Let the Intensity of the first earthquake be I1 and the second be I2.
Given M1=7.5
M2=6.7
Now M1=log(
)------1
M2=log(
)-----2
Now subtract 1 and 2 we get
M1-M2=log(
)
I1/I2=
I1=I2(
I1=I2*6.31
Assuming the missing parenthesis is at the end the simplified answer should be k-8
Answer:
Step-by-step explanation:
<u>Use the area equation:</u>
<u>Substitute values:</u>
- A = 1/2* 1 2/3 * 1 = 1/2*5/3 = 5/6 km²
P < or = 7.
P could be 7, 6, 5, 4, 3, 2, 1, or zero.
