ii.
To solve: The formed logarithmic equation to find the released energy.
USA:
GREECE:
JAPAN:
Given:
The Richter magnitudes are
Concept Used:
Calculation:
According to the problem statement, following equation has been formed:
Now solve equation (i) to obtain the energy released in the USA.
Thus,
Similarly, solve equation (ii) to obtain the energy released in the GREECE.
Thus,
And finally, solve the equation (iii) to obtain the energy released in JAPAN.
Thus,
Conclusion:
The energy released in USA, GREECE and JAPAN is
