A lunar eclipse happens when Earth is between the Sun and the Moon, which is a true statement about them.
When there is a lunar eclipse, the moon moves into a position where it will be in the Earth's shadow and will not be visible. This means that because the Earth sits between the sun and the moon, a shadow forms, and when the moon moves behind the Earth, the Earth prevents the moon from receiving light from the sun. If the eclipse is a total lunar eclipse, the Moon will spend roughly two hours traveling through the umbra (region of total shadow) cast by Earth. When the Moon merely passes through a portion of Earth's umbra or penumbra, a partial eclipse of the Moon occurs.

Answer:
Binary systems are the easiest, where there are two stars in a solar system instead of one.
Explanation:
When there are two stars in a solar system, instead of one, the stars orbit each other. Astronomers can measure quite a bit of information about the movement of the stars. This includes how fast they travel around each other and how often they fully orbit each other. From this information, the mass can be calculated. Note that this information can then be used to estimate the masses of other stars that fit the same type of categories in solar systems with a single star.
I don’t understand what the question is? But if you are asking which is a better deal it’s Lucky. You save more money overall.
Hope this was helpful :)
The most sensible answer is to:
A) Report his findings.
As a scientist it is his job to conduct experiments based on hypothesis or theories and from this experiments, give a detailed description, explanation, and conclusion about the experiment. This is the reason scientists and doctors write articles about their research, to make the public aware of such discoveries so that future researchers don't have to spend time valuable time and further studies can be based on such experimental report.
D) Would also be correct 'If' the scientist didn't find the expected answer to his hypothesis. This would cause the scientist to perform further experiments to find a reasonable justification and give a conclusion about it. If by the end of his studies, the research concludes that his hypothesis is incorrect, he must change his hypothesis based on scientific truth.
Both B) and C) are the least likely answers because:
B) is an immature action to take, showing the scientists lack of control. Throwing away experiment notes is not the wisest move to take as these notes not only provide valuable information about the experiment but can actually prove to be important data, that if analysed well it could show the scientist his mistake/error, a new unobseved pattern or give him a new hypothesis or idea. Thus proving to be very valuable.
C) As a scientist, it is his right to be a very genuine about his work as he is given a credibility by science. Lie is one of the greatest sin to a scientist as it causes his credibility to collapse and even lose his title as a scientist.
Answer:
Explanation:
There are 6 hours between 9 am to 3 pm
So steps per hour = 3409.66 steps
