B. Greenhouse technology
Since the green house will help keep the pest and harmful conditions. The greenhouse will be able to control temperatures and will keep out harmful bugs. You/I will be able to provide the tree with the perfect sequence of growth.
An equation showing the relationship between the THREE forces is R -W +F= 0
<h3>What is moment of force?</h3>
The equal and opposite force acting at a point from the axis of rotation is called the moment of force.
M = F x r
Given is a wheelbarrow and stones with a total mass of 43 kg. The wheelbarrow is in equilibrium with two of the three forces acting on it
Taking moment about the wheel, we get
-43x 9.81 x 0.6 + F x 1.5 =0
F = 43 x 0.6/1.5
F = 168.732 N (upward force)
Summation of forces in y direction is zero.
R -W +F= 0
Where, R is the normal force, W is the Weight force and F is the applied force.
Thus, this is the equation representing all the three forces acting on wheelbarrow.

To solve this problem we will first apply the principle of energy conservation, for which the elastic potential energy must be the same as the elastic kinetic energy of the simple harmonic movement of the system.
From this conservation it will be possible to find in total terms the total displacement of the system and thus replace it in the given function to find the time.
The potential energy stored would be

The kinetic energy would be

Here,


Now assuming the planned conservation of energy







So now using the equation previously given to describe the motion of the particle we have to





Therefore the correct option is B.
