Answer:
nothing
Explanation:If you ride a bike around the block and return to the exact point where you started, your displacement is zero.
By definition, displacement involves changing an object from its original position. No matter how far or for how long a body moves, if it returns to the position it started from, it has not been displaced at all. This means that the body has zero displacements.
It would be spectral class M

Answer:
Please see below as the answer is self-explanatory.
Explanation:
- If the potential at B is lower than A, and the potential at C is lower than B, this means that there is an electric field, directed from A to C.
- If a positively-charged particle is released at rest at point B, it will be accelerated by the electric field (which is a force per unit charge, so it produces an acceleration) in the same direction than the field (because it is a positive charge) towards point C.
