Answer:

They two waves has the same amplitude and frequency but different wavelengths.

Explanation: comparing the wave equation above with the general wave equation

y(x,t) = Asin(2Πft + 2Πx/¶)

Let ¶ be the wavelength

A is the amplitude

f is the frequency

t is the time

They two waves has the same amplitude and frequency but different wavelengths.

kati45 [8]

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.
