Conservation tillage practices help reduce soil erosion and maintain soil nutrient levels.
<u>Explanation:</u>
The approach that helps in the reduction of doing tillage practices and also reducing its frequency. this is done for obtaining certain benefits for both environment and economic. This mainly focuses on providing sustainability by leaving some plants remaining in the soil.
It aims in decreasing the emission of gases of greenhouse effects like carbon dioxide. Using these practices helps in reducing the erosion and runoffs. This will promote health of the soil because the nutrients are not take off form the soil due to soil erosion and runoffs.
Answer:
particles
Explanation:
in liquids, particle are close together
Answer:
a = 8.4 m / s²
Explanation:
The mean acceleration is defined by
a = (v_f- v₀) / (t_f - t₀)
where v are the final and initial velocities, respectively and t is the time interval
Let's apply this equation to our case
the final velocity is 99 m / s and the initial velocity is 57 m / s
a = (99 - 57) / (15 - 10)
a = 8.4 m / s²
This is true, The total energy when a body falls freely towards earth remains constant.
Answer:
Height of mirror 0.075 m
width of mirror 0.325 m
Explanation:
given data
wide = 1.3 m
high = 0.30 m
driver’s eyes = 0.50 m
rear window = 1.50 m
solution
we take here height / width of the mirror is
height / width = .................1
and
height /width of the window is
height /width = .................2
and
distance of eye / window by the mirror is
distance of eye / window = .................3
so here
θ = θi = θr ....................4
and tanθ for vertical is
tanθ =
tanθ = ....................5
so
h = ....................6
put here value and we get
h = 0.075 m
and
when we take here tanθ for horizontal than it will be
tanθ =
tanθ = .......................7
so
....................8
put here value and we get
w = 0.325 m
