Answer:
Distance travelled is 7 meters and the displacement is 3 meters
Earthquakes and volcanoes most commonly occur around plate boundaries because of the movement from the plate boundaries. The interactions between the plates by moving under, upon, or sliding against other boundaries may cause earthquakes and volcanoes.
Answer: B, C, A
Explanation:
Electrostatic force F = kq²/d²
Let the force on A be Fa, and B be Fb and C be Fc.
For Fa, distance between A and B is d, and distance between A and C is 2d
For Fb, distance between B and A is d, and distance between B and C is d
For Fc, distance between C and B is d, and distance between C and A is 2d
Also, the charge of each charge affects the sign of the force.
