The system of blocks has an acceleration in the left side. The force of friction opposing the motion of the 2kg block in the left side is ma+ force acting in the direction of friction =(2kg×3ms

)+2N=8N. Thus the force of friction acting between the two blocks is 8N.
Answer:
Diversity is about what makes each of us unique and includes our backgrounds, personality, life experiences and beliefs, all of the things that make us who we are. It is a combination of our differences that shape our view of the world, our perspective and our approach
