Answer:
Because plant means a life. Plants need foods and energy as same as human. So for a plant mostly need sun light and water.
They need water because water is collected through root of the plant and absorbed from the soil.
They need sun light because do the process of photosynthesis and plants need other gasses well as water and sun light for live and survive.

I'll answer since there are no answers to refer to. A jovian planet is pretty much a planet that doesn't have a solid surface. It's a planet made up primarily of gases hydrogen, nitrogen, helium, methane and so on
To solve this problem it is necessary to apply the kinematic equations of motion (vertical in this case) as well as the momentum conservation equations.
For conservation of the moment we have to
Where
Mass of each object
Initial velocity of arrow
= Final Velocity
Time in flight for arrow-apple combination is
Where,
h = Max height
g = Gravitational acceleration
Now after the impact arrow-apple combination have horizontal velocity V and it is
From the previous definition we have that the value of time would be,
Assuming the son's height is 1.85m, then we should
Applying again the conservation equation we can obtain the value of the apple mass as:
Therefore the mass of the apple was 140.7g
Well if the wire has an insane length or is made out of a high resistance material. But, you're probably looking for a resistor : R = U / I ; R = 20V / 0.25A
The answer:
we can use newton's second law for finding the value of acceleration
that is F=MxA
M the mass
A is the acceleration
F= P-Fk, Fk= -Mgcosθμ and P=Mgsinθ
μ is the coefficient of friction
The value of μ can be found with the above condition
(<span>pulled up a 28 ° rough ramp at constant speed)
</span>this implies the acceleration is equal to zero
100N - mgsin(28°) -mgcos(28°)μ<span> = 0 , from where </span>
μ= [100N - mgsin(28°)] / mgcos(28°)
μ=0.2
and then,
F=MxA= Mgsinθ -Mgcosθμ finally A=gsin28° -gcos28° x0.2 =2.6m/s²
