Correct answer choices are :

A) Humus

E) Manure

D) Nitrogen


Explanation:


Soil fertility leads to the capability of a soil to support agricultural plant growth, i.e. to produce plant environment and occur in continued and steady yields of high quality. A fertile soil will include all the important nutrients for basic plant nourishment, as well as other nutrients required in smaller amounts.

<h3><u>Answer;</u></h3>
  • <em>Humus</em>
  • <em>Manure</em>
  • <em>Nitrogen</em>
<h3><u>Explanation;</u></h3>
  • <em><u>Soil fertility is a characteristic of soil</u></em> that refers to the capability of soil to maintain and provide a suitable habitat for growth of agricultural crops, thus resulting to continuous productivity.
  • <em><u>The fertility of soil</u></em> may be influenced or enhanced by various factors which includes, <u><em>the soil structure, organic matter, soil pH, and water retention among other factors. </em></u>
  • <em><u>Humus, nitrogen, and manure </u></em>are among the factors that boosts or improves soil fertility, and thus enhances growth and sustainability of agricultural crops by the soil.

dybincka [34]

Answer:

544.65 ohm and 179.84 ohm

Explanation:

Hello

Let

Resistor 1 (R1) and Resistor 2 (R2)

in series R_{eq} =R1+R2      

in parallel

\frac{1}{R_{eqp} } =\frac{1}{R1} +\frac{1}{R2}\\\\R1=R_{eqs} -R2\\\\R1 =724.5-R2 (equation 1)\\ R_{eqp}}=\frac{R1*R2}{R1+R2}\\\\\ 135.2 = \frac{R1*R2}{R1+R2}(equation 2)\\\\\\\\replacing 1 in \ 2\\\\probema data

135.2=\frac{(724.5-R2)(R2)}{724.5-R2+R2} }\\135.2=\frac{(-R_{2} ^{2}+724.5R2) }{724.5}\\ 135.2*724.5=-R_{2} ^{2}+724.5R_{2}\\\\R_{2} ^{2} -724.5R_{2}  +97952.4 =0\\R_{2} =\frac{724.5 \±\sqrt{(-724.5^{2})-4(1)(97952.4) } }{2(1)}\\R_{2} =\frac{724.5\±\sqrt{(133092.25) } }{2(1)}\\\\R_{2} =\frac{724.5+364.81810}{2} \\R_{2} =544.65 ohm\\\\R_{2} =\frac{724.5-364.81810}{2} =179.84 ohm\\\\

let R2=544.65 and replace in equation 1

R1=724.5-544.65

R1=179.85

so, the resistors are 544.65 ohm and 179.84 ohm

A spaceship travels toward the Earth at a speed of 0.97c. The occupants of the ship are standing with their torsos parallel to t
Ket [755]

Answer:

Explanation:

We shall apply length contraction einstein's relativistic formula to calculate the length observed by observer on the earth . For the observer , increased length will be observed for an observer on the earth

L=\frac{.5}{\sqrt{1-(\frac{.97c}{c})^2 } }

L=\frac{.5}{.24}

L= 2.05

The length will appear to be 2.05 m . and width will appear to be .5 m  to the observer on the spaceship. . It is so because it is length which is moving parallel to the direction of travel. Width will remain unchanged.
