Answer:
The answer to your question is letter B.
Explanation:
To answer this question, we must remember the third law of motion of Newton that states that For every action, there is an equal and opposite reaction.
Then, if the action force is 40 N to the right, the reaction force must be 40 N to the left.
Answer:
26.56°
Explanation:
given,
horizontal distance travel by the ant = 2 m
vertical distance travel by the ant = 1 m
angle of the ant above the initial point = ?
using trigonometric function

θ is the angle of the ant form initial position
h is the height on the wall
x is the horizontal distance covered by the ant



hence, the angle made by the ant from the initial position is equal to 26.56°
I think the 3rd one is the answer
