Long wavelength corresponds to having lower frequency
We can solve the problem by requiring the equilibrium of the forces and the equilibrium of torques.
1) Equilibrium of forces:
where
is the weight of the person
is the weight of the scaffold
Re-arranging, we can write the equation as
(1)
2) Equilibrium of torques:
where 3 m and 2 m are the distances of the forces from the center of mass of the scaffold.
Using
and replacing T1 with (1), we find
from which we find
And then, substituting T2 into (1), we find
a. use increased crop diversity and fewer off the farm resources in order to reduce pressure on resources
Explanation:
A farmer using sustainable agricultural practices will use increased crop diversity and fewer off the farm resources in order to reduce dependency on other resources.
The major goal of sustainable agriculture is to cultivate plants and groom livestock in the best way that won't alter the environment.
- This usually entail the cultivation of different crops.
- Diversity of crops provides the means to sustain and retain soil fertility naturally without having to add fertilizers.
- In animal husbandry, some of wastes are used on farm and the excesses from the farm are used to feed livestock.
- Sustainable agriculture is a practice of self-reliant agriculture without infringing on the environment.

Answer:
a. A uniform disk of radius and mass .
Explanation:
The moment of inertia I of an object depends on a chosen axis and the mass of the object. Given the axis through the point, the inertia will be drawn from the uniform disc having a radius and the mass.
.
Work is closely related to energy. The work-energy principle states that an increase in the kinetic energy of a rigid body is caused by an equal amount of positive work.
So they are both closely related to each other.
