Answer:
8.6*10^5N
Explanation:
Pressure of the water = density of water * height of the water * acceleration due to gravity
Pressure of water = 1000*9.81*(2.5 + 8.50)
Pressure of the water = 107910 = 1.08*10^5
And Pressure = force / A
Force = Pressure * A(surface area of the container)
Force = 1.08*10^5 * 8 = 863280 = 8.6*10^5N
The 7.5 is a 100 times stronger than the 5.5 . The 100 comes from the increase in scale from 5.5 to 7.5 which is an increase of two so you multiply the strength of the weaker earthquake 10^7-5=10^2=100 and that gives you the strength of the stronger earthquake!
