Give a brief account of counter current mechanism!!​

The countercurrent mechanism helps to concentrate the filtrate which occurs in the loop of Henle and vasa recta in the medulla region of the kidney. The flow of fluids in opposite directions is maintained by their flow in the two loops- ascending and descending limbs of the loop of Henle and vasa recta.

t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanatio

explanation:

newton's third law, for every action there is an equal and opposite reaction.
