Answer:
The correct answer is letter b. less than
Explanation:
In the attached schematic figure, the lens (lens) is initially adjusted for a given distance from the object. If the object gets closer, the image loses its sharpness. To recover it, the lens settles down, increasing convergence, that is, decreasing the focal length.
If a group of scientists have access to one data, from the data they can draw conclusions either through mathematics or just thought experiments.
Those thought experiments is different for any scientist, no one thinks the same especially when the topic is difficult.
For example when talking about parallel universes, scientists have come up with the weirdest examples of a multiverse. Some thinking of a brane universe, while others say that its a landscape universe, quilted universe. All of their 'evidence' seems correct but they have opposite meanings.
A weird analogy is 'religion'. All the religions seem to have 'evidences' (hardly) that attract people towards it, they all make sense but that doesn't mean that their evidence is right.

Now if they're trying to break down the data using maths, there could be a great uncertainty and measurement error that if done enough could change the whole idea behind the data.
Interesting question, I can babble for days for this but lets keep it as that
Answer: D. 0.57
Explanation:
The formula to calculate the eccentricity 
of an ellipse is (assuming the moon's orbit in the shape of an ellipse):
Where:
is the apoapsis (the longest distance between the moon and its planet)
is the periapsis (the shortest distance between the moon and its planet)
Then:
This is the moon's orbital eccentricity
Answer:
direct current
Explanation:
it has a direct path to go down to reach the specific point
Average velocity is given by the ratio of total displacement /total time taken in order to do that
thus it will be
30.5-50.0/3 = 6.5 m/s
