A. anything less than 3.0 magnitude on a richters scale usually can't be felt by humans but instruments can pick it up.
might be 140mph, so that is a guess that i just made so plz let me know if im wrong or correct
The answer is B
because if you compare a regular road and ice... ice is smoother and therefore has less friction
Both magnitude and DIRECTION
For example,
• 12m East
• -2 miles
•9 meter north
• 8 miles up
