Question

(iv) Which part of the leaf carries out this process?
​

Answer 1

Here the Concept of Relative Velocity and Relative Acceleration as well as Third Equation of Motion has been used. We see that we are given the velocities and acceleration of both girl and boy. Even its given the distance between the boy and the girl. And we need to find the time taken by boy to reach the nearest position of catch the girl. Here we shall take the nearest position as where the boy catches girl. Firstly we shall find the relative velocities of boy and girl. Then we shall find relative acceleration and then using these, we can find the time taken.

Answer 2

Explanation:

photosynthesis, sugar and oxygen are produced from the carbon dioxide and water. Oxygen passes out of the leaf through the open stomata. The sugar enters the phloem and then travels throughout the plant.

Hope its help.
