Well, I'm not sure right now that it actually does.
But if it does, that's because the sun is about 400 times
FARTHER from the Earth than the moon is.
The correct answer is
B. Interference
D I think I really don’t know
Answer: It remains the same
Explanation:
The Conservation of Momentum principle establishes that the initial momentum must be equal to the final momentum :
(1)
In the case of the train, its initial momentum is:
(2)
Where is the mass of the train and is the initial velocity of the train
And, its final momentum is:
(3)
Where:
since we are told the mass of the train is doubled
since we are told the velocity of the train goes to half
Hence:
(4)
(5)
(6)
This means the momentum of the train remains the same.
It will accelerate at 6.2 m/s/s west.
