Answer:
Newton's second law of motion states that the acceleration of a system is directly proportional to and in the same direction as the net external force acting on the system, and inversely proportional to its mass. If the only force acting on an object is due to gravity, the object is in free fall.
The x component of the force is 8.4N * cos(31°) = 7.2N (2 s.f.)
A series circuit is a closed circuit in whicj the current flows through one path.
