Higher Power Efficiency and Eliminates Risk of Compressor Breakdown
Answer:
Say the full question I can't understand what it is
The answer is C I just took this quiz.
Each point in the chain supports the weight of all the mass below it.
At the bottom end of the chain, the weight is (175 x 9.8) = 1,715 N .
At the top of the chain, the weight is (175 + 12) x (9.8) = 1,833 N .
The tension in the chain varies linearly from 1,715N at the bottom
to 1,833N at the top.
That is not true.
<span>According
to the law of conservation of mass, in a chemical reaction, the mass of
the reactants will always be the same as the mass of the products.</span>
