Unfortunately, this test will not be able to receive a prize:
Too many missing explanations. More than 10 explanations simply repeat the correct answer. E.g. #q7, #q11, #q13 etc.
The original verdict was confirmed to be correct.
In addition to the above issues:
Too many missing explanations. More than 10 explanations simply repeat the correct answer. E.g.: #q5, #q7, #q9, #q11, #q13, #q14, #q21, #q23, #q25, #q26, #q30.
And if what I am saying is wrong, please give us explanations for some of the questions you have pointed out. So I can be convinced. Thank you
There's just question 23 with which I disagree: Gravity is simply a force which causes two bodies with mass to attract each other. "Height above the ground" is not the determining factor, rather it is the mass of the two objects as well as their distance (reflected in the formula for gravity F=G*m1*m2/r², where r is the distance and m is the respective mass). So the answer "The force of attraction between two objects" should not be incorrect and the other answer should be removed.
The answer which has been marked as correct, "The force of attraction between two objects because of its height above the ground" only makes sense when there is a "height" and a "ground" to go off on. To give an example, gravity also acts as a (really tiny) force between two atoms[3], yet the terms "height" and "ground" don't make any sense here - what exactly is the "ground" of an atom? (See also: The Cavendish experiment[4]).
To recap, the provided answer is only correct for a certain subset of gravitational attractions which the question did not specify (not a big deal), and the answer "The force of attraction between two objects" should definitely not be incorrect as it is a commonly used definition for gravity[2][5][6][7] (a pretty big deal).
