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 :
It is the release of a relatively large amount of energy in cells by the breakdown of food substances in the presence of oxygen:
Glucose + Oxygen → Carbon Dioxide + Water.
