Why are animal cells square and animal cells round
irina [24]
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.

Consider two transformers. Transformer A has 300 turns on its primary and 500 turns on its secondary. Transformer B has 250 turn
rusak2 [61]

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 N_p=300

Numb er of turns in secondary N_s=500

Now consider second transformer

Number of turns in primary N_p=250

Number of turns in secondary N_s=1000

Now it is given that same voltage of 50 volt is applied to primary of both the transformer.

For second transformer

\frac{N_p}{N_s}=\frac{V_p}{V_s}

\frac{250}{1000}=\frac{50}{V_s}

V_s=200volt

So secondary voltage on second transformer is 200 volt
