D.multiple. because you always have to double check to see if its true or not. Majority rule.
A falling object (directly downward) is slowed down by air resistance. In turn it would take longer to fall.
Answer:
v₂ = 63.62 m / s
Explanation:
For this exercise in fluid mechanics we will use Bernoulli's equation
P₁ + ρ g v₁² + ρ g y₁ = P₂ + ρ g v₂² + ρ g y₂
where the subscript 1 refers to the inside of the wing and the subscript 2 to the top of the wing.
We will assume that the distance between the two parts is small, so y₁ = y₂
P₁-P₂ = ρ g (v₂² - v₁²)
pressure is defined by
P = F / A
we substitute
ΔF / A = ρ g (v₂² - v₁²)
v₂² = 
suppose that the area of the wing is A = 1 m²
we substitute
v₂² = 
v₂² = 79.10 + 3969
v₂ = √4048.1
v₂ = 63.62 m / s
Answer: D
<u></u>
X: positive
Y: negative
Explanation:
It's either A or D and I chose A and got it wrong.
Explanation:
Continental rifts and mid-ocean ridges are both features of a divergent plate margin.
In both cases plates are moving away from one another. Therefore they are creating new land masses.
- A continental drift like the east African rift valley is where a continent begins to pull apart or diverges.
- A mid-ocean ridge is divergent margin in the ocean.
They are different in that, continental rift occurs within the continental plate that are on land.
But:
Mid-ocean ridges are in the oceanic crust in the ocean . They form the largest physiographic structure on the earth surface called the mid-ocean ridge.
