Question

All forces must have

and
OA) power, energy
OB) power, a direction
O a magnitude; energy
OD) a magnitude, a direction

Answer 1

All forces must have a magnitude and a direction.

Step-by-step explanation:

If object A uses a force on object B, formerly object B must use a force of similar magnitude and opposing direction behind on object A.This law describes a certain proportion in nature: forces perpetually happen in pairs, and one group cannot use a force on different without enduring a force itself.

Sometimes lead to this law loosely as action-reaction, where the force exercised is the action and the force experienced as a result is the reaction. An example, rockets move forward by expelling gas backward at high velocity.
