I to have no clue as well
Plant cells are not necessarily square, but they due tend to have distinct edges and be kind of rectangular. This structure is caused by the cell wall which is very rigid and therefore forces the cell to have a more defined shape. However, animal cells do not have a cell wall but only the plasma membrane. Which is is why it's round.
Answer: here you go i have to put 20 letters in so just ignore this and look at the link.
Mass - the answer is mass. Since I need to write a bit more, the answers are not density, weight, gravity, size or anything like that!
Answer:
Secondary voltage on second transformer is 200 volt.
Explanation:
It is given two transformer
Let us consider first transformer.
Number of turns in primary 
Numb er of turns in secondary 
Now consider second transformer
Number of turns in primary 
Number of turns in secondary 
Now it is given that same voltage of 50 volt is applied to primary of both the transformer.
For second transformer



So secondary voltage on second transformer is 200 volt
