Answer: <em>Mountains </em>can alter wind flow and create a rain shadow effect.
Explanation:
Rain shadow effects :An area having less precipitation of less rain fall due to the effect of the topographic (physical features of that area ) barriers( to prevent the movement) like mountain or mountains range.
Sides of mountain:
- Windward side: Area or side where high rainfall occurs. Wind prevailing loose their moisture on this side which leads to high rainfall on this side.
- Leeward side : Area or side where low rainfall occurs.

Answer:
a) a = 3.72 m / s², b) a = -18.75 m / s²
Explanation:
a) Let's use kinematics to find the acceleration before the collision
v = v₀ + at
as part of rest the v₀ = 0
a = v / t
Let's reduce the magnitudes to the SI system
v = 115 km / h (1000 m / 1km) (1h / 3600s)
v = 31.94 m / s
v₂ = 60 km / h = 16.66 m / s
l
et's calculate
a = 31.94 / 8.58
a = 3.72 m / s²
b) For the operational average during the collision let's use the relationship between momentum and momentum
I = Δp
F Δt = m v_f - m v₀
F =
F = m [16.66 - 31.94] / 0.815
F = m (-18.75)
Having the force let's use Newton's second law
F = m a
-18.75 m = m a
a = -18.75 m / s²
Answer:
-0.912 m/s
Explanation:
When the package is thrown out, momentum is conserved. The total momentum after is the same as the total momentum before, which is 0, since the boat was initially at rest.
where are the mass of the child, the boat and the package, respectively.
are the velocity of the package and the boat after throwing.
