How much greater is the shaking produced by a magnitude 8 earthquake than a magnitude 5 earthquake using the richter scale?
a. 10,000 times greater
b. 100 times greater
c. 3,000 times greater
d. 1,000 times greater

The shaking produced by a magnitude 8 earthquake is 3000 times greater than a magnitude 5 earthquake using a Richter scale. The answer is letter C. As the number in the Richter scale increases, the magnitude of earthquake also increases.

Unless the ring by design will have restriction for any outward expansion. The hole will get larger / bigger as you heat this up. The more you heat an object the more it expands, thus the larger the hole gets. The only case is when outward expansion is restricted, the expansion will be inward as it is the only direction the ring can expand to.
