A 4x100 relay is where 4 people run 100 meters and a 4x400 relay is where 4 people run 400 meters
The acceleration would be 6m/sThis is because of the formula, "f/m=a" to find the acceleration; We would need to subtract the force of the friction which equals 1380, then divide that by the mass (which was 230) to get the answer 6
No they do not they just need to be in each other's magnetic field
That's ONLY true when the pendulum is hanging
in the center position and not moving.
