Mathew, a farmer, cultivates monocultures of wheat. What negative effect will monoculture farming have on Mathew’s land? A. crop
Firdavs [7]

<u>Answer</u>:

Mathew, a farmer, cultivates monocultures of wheat. The negative effect that the monoculture farming have on Mathew’s land will be C. nutrients will not be recycled into the soil.

<u>Explanation</u>:

Monoculture farming is the practice of cultivating a single species of crop or plant at a time on farm. Growing the same crop again on the same land yearly destroys the nutrient of soil. It destroy the quality of soil and made farmers use more fertilizers.

The quality of the crop is degraded as it will not get the essential nutrients. But this practice is very popular as it increases the productivity of a particular species of crops. So by using this method, mathew will get these disadvantages.

Other options are incorrect as this practice will not cause water pollution. Neither it would produce greenhouse gases, nor it would decrease crop productivity.

La masa de un objeto en la tierra es de 100 kg.
andreev551 [17]

Answer:

a) 980 N

b) 100 kg

c)  163.33 N

Explanation:

a)

The weight of the object on Earth is the product of its mass times the acceleration due to gravity, that is:

W=m\,g=(100\,\,kg)\,g=(100\,\,kg)\,(9.8\,\,m/s^2)=980\,\,N

b)

The mass of the object on the moon, is exactly the same (100 kg) since mass is an inherited value of the object.

c)

Considering that the acceleration of gravity on the Moon is about 1/6 that we have on earth (g), then the weight of the object on the Moon becomes:

W=m\,\frac{g}{6} =\frac{980}{6}\,\,N=163.33\,\,N

What decibel reading corresponds to a pressure amplitude of 0.2 W/m^2?
horsena [70]

I  = pressure amplitude given = 0.2 W/m²

dB = decibel reading

decibel reading from the pressure amplitude is given as

dB = 10 log₁₀ (I/10⁻¹²)

inserting the values in the above equation

dB = 10 log₁₀ (0.2/10⁻¹²)

dB = 10 log₁₀ (2 x 10⁻¹/10⁻¹²)

dB = 10 log₁₀ (2 x 10⁻¹.10¹²)

dB = 10 log₁₀ (2 x 10¹²⁻¹)

dB = 10 log₁₀ (2 x 10¹¹)

dB = 113.01 db

hence the decibel reading comes out to be 113.01 db
