What is the magnitude in the richer scale of an earthquake that released in 10¹⁶ joules of energy

E = 3.698761784x1016 ft lb. Thus, log10 E2 - log10 E1 = 1.5 and log10(E2/E1) = 1.5.

...

The Richter Scale.

Magnitude Released Energy (to the nearest integer)

5.5 4,466,835,921,510 J

6 25,118,864,315,096 J

6.5 141,253,754,462,275

7. 7 794,328,234,724,282Step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
