I know one answer is an observer on earth sees a lunar eclipse
Answer:
The person must be located in the Equator Line. The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Explanation:
Physically speaking, the centripetal acceleration (
), measured in meters per square second, experienced by a person is defined by the following expression:
(1)
Where:
- Angular speed of the Earth, measured in radians per second.
- Distance perpendicular to the rotation axis, measured in meters.
Since rotation axis passes through poles and distance described above is directly proportional to centripetal acceleration. The person must be located in the Equator Line, which is equivalent to the radius of the planet.
In addition, the angular speed of the Earth can be calculated in terms of its period (
), measured in seconds:
(2)
If we know that 
and 
, then the maximum centripetal acceleration experienced by a person is:
The maximum centripetal acceleration experienced by a person is 0.0337 meters per square second.
Answer:
It would be (a)
Explanation:
A theory is something that can be proved through rigorous and repeated experimentation, while choice (b) sounds tempting i believe it fails at the fact that it says that a theory is an "agreement", sure an agreement could be reached by while trained scientists but that does not necessarily mean that what the scientists agree upon is rigorously tested and repeatable, and so therefore cannot be assumed
That is what I think
Hope this helps :)
