The answer is 45 degrees. I am not doing a field experiment for you that involves a cannon and a day's work, for 5 points.
Answer:
2.75 N
Explanation:
Given that,
Box A has a mass 21.0 kg and box B has a mass 8.0 kg.
A horizontal force of 100N is exerted on box A.
Let a be the acceleration of the system. Using second law of motion,

Now applying Newton's second law to box B. So,

So, 2.75 N is the force that box A exerts on box B.
Typically , atom gain or lose electrons to achieve A stable electron configuration
The formation of an ionic bond involves : Transfer of electrons
In the formation of ionic bond, the electron is closer to being stolen , not shared
