8) Better utilization of hybrid seeds.

9) A shorter growing season and more effective use of the land.

10) More precise harvest date prediction.

Explanation:

Plants are grown using the indirect seedling technique known as transplantation. This process involves growing seeds into seedlings inside nurseries, a controlled environment, and then transferring those seedlings to a field.

The seeds are not exposed to the risk of direct seedling damage from birds, rats, snails, and other biotic and abiotic stressors, which is one of the many benefits of this method.

Since the primary plant and the weeds are not the same age, there is a less crop-weed competition using this technique.

With this technique, even alien plants have time to adapt and flourish in their new environment.

There are many reasons. The easiest solution is because the rain that we remember acidic has a low pH; it has a better amount of hydrogen ions.

Acid rain manipulation implies three adjustments a notably extra complicated and cumbersome regulatory program beneath the Clean Air Act, new emission manipulation prices for initial rollback requirements and next offsets, and on account of these, new impediments to utility and commercial plant creation, expansion, and modernization.

The Acid Rain application (ARP) has brought widespread discounts in sulfur dioxide (SO2) and nitrogen oxide (NOX) emissions from fossil fuel-fired strength flora, full-size environmental and human fitness blessings, and a ways lower-than-anticipated prices.

The ratio of their amplitudes is 3.

The relation between energy and amplitude is as follows:

[tex]E_{1} = \frac{1}{2} KA_{1} ^{2}[/tex]

The distance traveled by the object from its initial position is 384 cm.

Distance is the sum of an object's movements, regardless of direction. Without respect to the object's starting or finishing positions, distance can be defined as the amount of space it has traveled.

An object is moving in a straight path.

The speed of the object from its initial position is 12.8 cm/s.

The object is moving for 05 minutes.

Then, t = 0.5 min = 0.5 × 60 = 30 seconds.

Now, the speed of an object is the distance of the object per unit time.

Therefore,

s = d / t

d = s × t

d = ( 12.8 cm/s ) × ( 30 s )

d = 384 cm

Hence, the object's position from its initial position is 384 cm.

(a) The position-time equations for fishing boat is x = 3.4t + 40.8

(b) The time taken for the speedboat to catch up with the fishing boat is 7.1 seconds.

The position-time equations for fishing boat will be obtained by applying the principle of relative velocity as follows;

Let the time when the speedboat catches up = t

let the total time spent by fishing boat = t + 12

x = 3.4(t + 12)

x = 3.4t + 40.8

fishing boat is moving at a constant speed = 3.4 m/s

speed boat started moving 12 seconds later,

distance between the boats = 3.4 m/s  x 12 s = 40.8 m

v = u + at

v = 2.8 + 1.7t

set up the following equation to determine the time when the two boats meet.

vt - x = 40.8

t(2.8 + 1.7t) -  (3.4t + 40.8) = 40.8

2.8t + 1.7t² - 3.4t - 40.8 = 40.8

1.7t² - 0.6t  - 81.6 = 0

solve the quadratic equation using formula method as shown below;

a = 1.7, b = -0.6, c = -81.6

In order to not to sink in snow they Wear shoes with a much larger area on the bottom to increase the surface area of their feet in contact with the snow

The size of the snow shoes prevents them from sinking into the snow. They have a big surface. since the relationship between surface area and pressure is inverse. Therefore, when the surface area is big, less pressure will be placed on the ground by the shoes.

In comparison to the bottoms of shoes alone, the snowshoes have a larger contact surface with the snow. Because they cover a larger surface area than would be the case if he were wearing only shoes, they lessen the pressure that the person's weight puts on the snow. will not become as firmly embedded in the snow as a result

If we try to walk on snow, our feet will sink in the snow because our feet has less surface area.

We know that lesser the surface area the more is the pressure on the surface. If we put on skies, we can move over the snow easily because skies have larger surface area and hence decrease the pressure on the snow.

The skateboarder will travel a distance of 9.19 m

We know that,

a = ( v - u ) / t

Δv = ( v + u ) / 2 ( If acceleration is constant )

Δv = d / t

where,

a = Acceleration

v= Final velocity

u = Initial velocity

t = Time taken

d = Displacement

Δv = Average velocity

Given that,

u = 1.8 m / s

a = 1.5 m / s²

t = 2.5 s

a = ( v - u ) / t

1.5 = ( v - 1.8 ) / 2.5

v = 3.75 + 1.8

v = 5.55 m / s

Δv = ( 5.55 + 1.8 ) / 2

Δv  = 3.675 m / s

d = Δv * t = 3.675 * 2.5

The size, pace, and volume of material transported by a moving lahar can constantly alter as it rushes downstream. It resembles a swirling slurry of wet concrete.

The melting of snow and ice as well as the ingestion of river or lake water by the moving slurry may both add to its water consumption.
