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 :
Transportation is the process of movement of water and minerals to all parts of the plant body. Plants have a specialized system that enables them to distribute water and nutrients throughout their body. They use several processes such as translocation, absorption, storage and utilization of water.
The water and minerals are transported in plants by two types of conducting tissues:
