A friend tells you he witnessed books and other objects falling off his bookcase during an earthquake. What was the magnitude of this earthquake but on the modified Mercalli scale?

This is a true statement  hope this : )

Iwould say this is falsedefinition: toward or near the equatorhope that : )

It should be a because the dilation changes the sides but not angles because in all shapes you have a certain degree number to add up to like for example a triangle is always 180 degrees
