Convergent evolution involves the independent evolution of similar traits in different species due to similar environmental pressures. The correct matches are:
Therefore, the correct option is (1): A-III, B-IV, C-II, D-I.
A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
