The energy magnitude M of an earthquake can be modeled by the equation M=(2/3)log E - 9.9, where E is the amount of energy released. What is the magnitude of an earthquake with an energy release of 7.079 X 10^26? Round your answer to the nearest whole number.

magnitude of an earthquake with an energy release of 7.079 X 10^26 =8

Step-by-step explanation:

Given that the magnitude M of an earthquake can be expressed by the equation

M=(2/3)log E - 9.9

Given that Energy release , E=7.079 X 10^26

Magnotude , M=(2/3)log E - 9.9

=2/3 log7.079 X 10^26 -9.9

2/3 x 2.8499719  -9.9

17.8999813 -9.9

=7.9999

rounded to 8 magnitude

i dont know

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
