Answer:
C. 0 N
Explanation:
In the absence of external forces, a body in motion will stay in motion.
F = ma
F = 6.0(0) = 0
When the two forces are acting in the opposite direction, then the resultant of the two vectors will be at a minimum. The value of the force will be either 2 Newton or -2 newton.
<span>. It is the simplest
way to prove and explain the situation under which the resultant of the two
vectors will be at a minimum. The situation under which the resultant of the
two vectors will be maximum is when the two forces of 5N and 7n will act in the
same direction and create a combines force of 12N.</span>
Explanation:
Trees, because of their height, are natural lightning rods. Electricity seeks the path of least resistance, and the moisture inside a tree is a much better conductor than air. This means a tree provides the preferred path for lightning to reach the ground.
