The initial results seemed promising, but the final effects were kind of disappointing.
In the given sentence above, the unnecessary qualifier that needs to be removed is "kind of". It is an informal expression which is usually used as meaningless fillers. So, the final sentence will be:
The initial results seemed promising, but the final effects were disappointing.
Answer:
C. They act up on two different bodies.
Explanation:
Newton's third law of motion states that for every action there is an equal and opposite reaction.
Action-reaction force pairs make it possible for fishes to swim, birds to fly, cars to move etc.
For example, while driving down the road, a firefly strikes the windshield of a car (Action) and makes a quite obvious mess in front of the face of the driver (Reaction) i.e the firefly hit the car and the car hits the firefly.
The ultimately implies that, in every interaction, there is a pair of forces acting on two different interacting objects or bodies.
Hence, the statement which is true about action and reaction forces with respect to Newton's third law of motion is that they act up on two different bodies.
In conclusion, action-reaction force pairs are characterized by the following statements;
I. They act up on two different bodies.
II. The forces are equal in magnitude but opposite in direction.
III. The forces are the same type such as magnetic force, contact force or gravitational force.
