**Step-by-Step Solution:** 1. **Understanding Inertia**: Inertia is the property of an object to remain at rest or in uniform motion unless acted upon by an external force. In this case, the fruits hanging from the branches of a tree have inertia and tend to stay at rest. 2. **Initial State**: When the fruits are hanging on the branches, both the fruits and the tree are at rest. The fruits are attached to the tree by weak connections. 3. **Applying Force**: When people shake the branches of the tree, they apply a force to the tree. This force causes the tree to move in the direction of the shake. ...

In fruit trees a disease 'exanthema' is caused by the deficiency of :

A fruit which is at 20 m above a lake suddenly detaches from the tree.A fish inside the lake , in the line of fall of fruit,is looking at fruit when fruit is at 12.8 m above the water surface.Speed of fruit as observed by fish (μ_(water)=4/3 and g=10m/s^2)

In nature, the failure of structural members usually result from large torque because of twisting or bending rather than due to tensile or compressive strains. This process of structural breakdown is called buckling and in cases of tall cylindrical structures like trees, the torque is caused by its own weight bending the structure. Thus, the vertical through the centre of gravity does not fall within the base. The elastic torque caused because of this bending about the central axis of the tree is given by (Ypir^(4))/(4R) . Y is the Young's modulus, r is the radius of the trunk and R is the radius of curvature of the bent surface along the height of the tree containing the centre of gravity (the neutral surface). Estimate the critical height of a tree for a given radius of the trunk.
