<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.

A toy airplane, flying in a horizontal, circular
Goshia [24]

Answer:

8.4 m/s

Explanation:

The toy completes 10 circle in 30 seconds. So its frequency of revolution is

f=\frac{10}{30 s}=0.33 Hz

The periof of revolution is the reciprocal of the frequency, so

T=\frac{1}{f}=\frac{1}{0.33 Hz}=3 s

The radius of the circular path is

r = 4.0 m

So the total distance covered by the toy in one circle is the length of the circumference:

2\pi r

And so the average speed is

v=\frac{2\pi r}{T}=\frac{2\pi (4.0 m)}{3 s}=8.4 m/s

The least count of stopwatch is 0.2s.The time of 20 oscillations of a pendulum was measured to be 25s.Find the percentage error
Svet_ta [14]

Answer:

0.8%

Explanation:

We are given;

Number of oscillations; n = 20

Time taken; t = 25 s

Formula for period of oscillation;

T = t/n = 25/20 = 1.25 s

We are told that the least count is 0.2 s. Thus, error is; ΔT = 0.2 s

percentage error in the measurement of time is given by;

(0.2/(20 × 1.25)) × 100% = 0.8%

The magnetic lines of force always travel from north to south true or false
kumpel [21]

Answer:

True

Explanation:

Magnetic field lines outside of a permanent magnet always run from the north magnetic pole to the south magnetic pole. Therefore, the magnetic field lines of the earth run from the southern geographic hemisphere towards the northern geographic hemisphere.
