Answer:
Explanation:
In an elliptical orbit , the angular momentum of the planet remains constant because velocity of planet makes a right angle to the direction to the star .
mvr = constant .
mv₁r₁ = mv₂r₂
v₁r₁ = v₂r₂
v₁ x 21 = 38 x 75
v₁ = 135.71 km/s .
Flowing water. As a turbine is creating energy, as is a generator and a reservoir just holds still water. Flowing water can be pumped through a turbine or hydro scheme and be turned into energy. Another thing, as it says potential, it’s referring to something that could be/isn’t yet
Answer:
Yes I think... But the joke is it is a walk then.
I would say the answer is B. That's what makes the most sense to me but I'm not certain.
